Colour cast and darkening on import

I've just imported photographs taken with a new camera (Canon 7D). The photos look fine at first, whilst rendering the preview and the histogram is "calculating ...", but then change, becoming darker, with an orange cast. This is not happening to all the photos, but all were taken in the same lighting, with flash. I've seen this happen with importing photographs from other Canon cameras (300D, 400D), but never to such an extent.
I'm using LR2 V2.6 RC (625842).
Computer is a MacBook Pro, Intel Core Duo. Screen is calibrated regularly.

A few things I might want to add/comment on the different posts:

... Colour profiles are specific to a device, and are such things as ACR 4, Camera Landscape, or however they are named for your particular camera. The colour space that Lightroom uses is a special version of Kodak ProPhoto RGB (called Mellisa, named after its developer). When you export an image you must give it a space (usually sRGB) . You would attach a profile for a specific device (such as a printer profile). Your monitor should also have its own profile (set by the device and software you use for calibration).
I don't quite agree:
What you refer to as Colour profiles are called Camera (Calibration) Profiles (ACR 4, Camera Landscape etc.)
Color profiles (also known as ICC profiles) are used to describe the relation of data in the so called profile connection space (PCS) to either a specific device's color space or another specific color space (e.g. ProPhoto RGB, sRGB, ...)

If you set the camera to, say, vivid, LR shoud respect that WHEN RENDERING. It shouldn't mess with the raw data. It would just be the first few lines of the devolop history. If you want LR to not do that, set the camera to its defaults, or fix it in develop later. It's still 100% under your control.
Agree, that this would need an ideal world where the camera manufacturers documented their formats.
If LR would have to respect a specific camera setting when rendering, it would have to implement/reengineer all possible presets (Picture Styles, Picture Controls, ....) for all manufacturers and all models of cameras. Presently, Adobe only provides several camera profiles for Canon and Nikon.

Raw is raw. White balance, color saturation, contrast, and sharpness settings, etc., do not change the raw data at all, other than coming along for the ride as metadata. IMHO, programs like LR should respect those metadatal values when rendering.
LR does respect the white balance setting active at the time of the shot and adapt it to its rendering. Other settings, like saturation, contrast, sharpness etc. do not have an effect on LRs rendering.

Colour Casts in Prints From Aperture

Hello,
I have read reams of material on calibration and profiling -- probably too much, because I'm more confused than I
was when I started.
This is my set up:
Nikon D300.
Mac Pro + GeForce 7300GT + Mac Cinema Display (20 inch).
Photoshop CS3 + Apple Aperture (2.1)
HP Photosmart 8250 (with HP cartridges)
This is my general workflow:
Pictures imported from camera into Aperture. Best shots are roundtripped to Photoshop, tweaked and then
re-imported back into Aperture as 16bit tiffs. A lot of these .tiffs are exported from CS3 in Lab Color Mode (I
don't know if this makes any difference -- I'm clutching at straws!)
This is my problem:
A3 prints of my shots done by a local photography shop look amazing. The colours match the colours I see on my
monitor. They're crisp and bright and everything I could wish for.
However I have tried printing A4 prints locally (from Aperture) on my printer and there are different coloured
casts that ruin the pictures.
I have tried different Aperture device profiles... including the System Managed profile & the profile for the HP
photo paper that I use and the shots have either a strong yellow cast or a strong pink cast depending upon the
profile I use.
My set-up hasn't been calibrated, and -- at this point in time -- I can't afford a calibrating device... can
anyone make any suggestions as to how I can get better results printing at home through Aperture, please?
Thank you very much!
Adam

I no longer get a colour cast.
I started with 1.5 and had some books printed these were fine. My old Canon 965i was used for printing and I got some casts adn I decided to get the B9180. Just before this I switched to Aperture 2 and now 2.1. Immediately I had colour casts and through this forum I found that I was not alone. The general view at that time was that it was a calibration issue but enough people who knew what they were talking about disproved that. The various options were to print through IPhoto, PS, PSE or some other external soutce. We all to a greater or less degree had some success.
During this time 2.1.1 came out and HP appeared to offer an updated driver.
In my case I re-installed everything, including the printer Firmware and carefully read everything that everybody had to say on the subject, thus in ColrSync I made sure that I had the same paper specified, that I specified it in soft proofing and that I specified it in the print menu and I variously set my Gamma between 1.05 and 1.2. I no longer have the cast but usualyl I have to do some tweaking and use a few sheets. Mostly this is with adjusting the Gamma.
I cannot understand teh attitude of Apple on this topic and some others whereby they have professionals dependent on their product andthey do not, as I woudl expect in a customer support oriented organisation, even acknowledge teh problem, let alone give out any information. I would be happer (if I was a pro) if I heard comforting words like 'We know about this, it seems to be caused by xxx and we are working on a solution but in the meantime try bbbb.'
The principle, in my view, should be 'You be the photographer, we will provide the tools.'

Colour Cast in Adobe products

Hi all.
I am sure someone out there can help me. I have installed CS, CS2 and now LR2.3, and every time I install an Adobe product, I struggle against reddish or orangish colour casts in my images. The same images opened in a variety of other progams do not show this colour cast.
The following link shows an NEF image converted to greyscale in LR 2.3. If I keep it as a colour image and completely desaturate it, it has the same colour.
Can anyone explain the colour cast, and how to ger rid of it. If you look at the thumbnails, you will see ther predominately warm cast they all have.
Here is the link:

Thanks in advance.

It may have been your Corel software rather than a wrong monitor profile from the manufacturer that caused your issue, Johnny. I had a similar problem when LR1 came out and it was caused by a color management profile that loaded into Windows at bootup that I had completely forgotten was installed when I first installed Corel software, and it messed LR's color up.
But I found the software eyeball calibration programs including PS Gamma to be inadequate. I mean, try it, sure, but if your results are still disappointing, especially when you try to match what you see on your monitor to what you get from a printer, do yourself a favor and get a hardware calibrator. You can spend hundreds of dollars for them, and I'm sure in many cases the expensive ones are worth every penny, just as you can justify expensive monitors and printers too for critical photo work, but my budget is much more modest. Still I found the hardware Spyder2 Express (currently $62 on amazon) color and gamma monitor calibrator to be an excellent value and
way more effective matching monitor to printer output in Lighhtroom than the do-it-yourself free online and built-in software calibrators. I saved more in photo ink and paper in not having to redo print jobs with different settings to get printed photos to look right than I spent for the Spyder2.
Not everybody likes them, as you'll see in Amazon reviews. You have to read S2E's readme file and follow the directions to the letter, with absolutely no shortcuts, to get good results with these, including being careful before calibrating to restore monitor defaults and set a 6500K color temperature, and have the monitor warmed up for one hour and the colorimeter warmed up for five minutes, and the room darkened with no light hitting the monitor as you calibrate; don't just try to use a hardware calibrator out of the box or follow a quick-and-dirty plug-and-pray approach as it would seem you could do, or they will disappoint, too, in my experience. Because I have a consumer-priced LCD monitor, and they are
not good on color and gamma accuracy as a rule, I do still sometimes have to make minor adjustments to monitor settings after calibrating or minor changes to printer settings to match print to monitor, but it's much closer using hardware calibration than not.

Why do my black and white prints have a colour cast?

I've been trying to print some old black and white photos that I've scanned into iPhoto. Last year this worked fine, but now all the prints have a pinkish-brown colour cast. As a check, I opened the same photos in Preview and printed from there and they all printed perfectly, so the problem is in iPhoto. I've been through all the colour-related options in the iPhoto print menu but to no avail - no setting makes any difference, not even ticking the greyscale printing option. Does anyone have any ideas? I'm using iPhoto 09.

A good general step for strange issues is to renew the iPhoto preference file - quit iPhoto and go to "your user name" ==> library ==> preferences ==> com.apple.iPhoto.plist and trash it - launch iPhoto which creates a fresh new default preference file and reset any personal preferences you have changed and if you have moved the iPhoto library repoint to it. This may help
This does not affect your photos or any database information (keywords, faces, places, ratings, etc) in any way - they are stored in the iPhoto library - the iPhoto preference file simply controls how iPhoto works - which is why renewing it is a good first step.

As RAW images import into LR I watch as they post but then they seem to update and darken. Help!

I'm shooting in RAW on a Sony a900 and the images look fine on the back of the camera. When I import the raw images to LR, as I watch them come in they look fine, but once all of them get into the library I watch as something seems to update and darken all of them. I have the imports set as default settings. It's taking a lot more time for post-processing and driving me crazy. Anyone got some insight on a setting to change to fix it?
Thanks!

I use a mac ios and shoot raw in a cannon 5d mark ii and shortly upon import of my images lightroom darkens and changes my images. This has happened before but not every time. The strange part is my last shoot had the same camera setting but this did not happen. The images i have now i can not use after lightroom has automatically altered them even if i try editing back to how they looked upon import

First thing to do is to change the default camera profile applied in Lightroom to camera standard (assuming that you shoot Canon or Nikon). Also make sure that your camera is NOT set up to use any of the HDR modes. Nikon calls those Active Dynamic Lighting. On Canons you often see things like highlight priority mode or "Auto Lighting Optimizer". Make sure that the picture style is set to standard and that for newer Canons the HDR mode is turned off. Most of the HDR modes simply underexpose the image and then add an instruction in the raw file to compensate for this to prevent highlights from being blown out. This causes more noise in the shadows and if you know what you are doing there is no point to this as you should simply expose correctly and get the highest quality raw.
Lastly, make sure that in Lightroom you have not checked "Apply Auto Tone Adjustments" in Preferences->Presets. This should make the default rendering of the raw files the same as the in-camera jpeg (what the camera shows on the back even if you shoot raw) but still give you all the latitude of raw files.

Colour cast in ACR from Canon G11

Hi all,
I recently posted this question on the Lightroom Forum where I did recieved some useful answers, but unfortunaly the solution is not really workable in the long term. As the issue I am having is almost certainly related to ACR, I thought I'd post the question here too.
I bought Lightroom 3 a month or so ago, mainly to work with the RAW output from my Canon G11. The majority of the shots want to process are taken underwater around the UK coast. When imported into LR3 the shots take on a very strong green colour cast, even though I set the manual white balance at regular intervals. By comparison, Canon DPP imports the RAW files correctly (what I consider correct), and I get the same correct results with Raw Therapee, GIMP and Capture 1. I do, however, get the same colour cast problem importing in to Photoshop Elements 8, which convinces me ACR is at the root of the problem. I am using ACR 6.1 for both LR and PSE8. I would expect Canon DPP to be correct as it is processing it's own RAW files, but as the other RAW converters match the Canon output, this too points at an issue in ACR.
I've scanned both the Adobe LR and ACR forums, but can not see any posts where people are having similar issues to me. I did find several post's saying that ACR's support of the Canon G11 was now finished, maybe it has just been tuned for land based shots, not underwater. I tried to install the Release Candidate of ACR 6.2 at the weekend, but got a message on the lines of 'Not for this product' (I forget the exact words), so gave up on that.
A short while ago I did a test import with a RAW file taken in similar conditions to my shots, but using a Canon 5D MkII. This imported correctly, which implies the issue is related to the G11. I was not able to do a test import my shots as the person helping has an older version of ACR which does not include the G11 support.
I have tried using Adobe DNG Converter, to no avail, and I have also tried all the white balance pre-sets within LR3. The custom white balance picker does not give sensible results, it just changes the shots to a slightly different shade of green. Being aggressive with LR3 setting can make improvements (Camera Calibration RGB hue's plus the tint and temperature for the white balance for example), but it's a slow, shot by shot process, and still does not produce a usable finished product, or even a reasonable starting point for fine tuning.
As a work around I can open the RAW files in Canon DPP and output to TIF, which LR3 then opens correctly. I believe, however, that as I'm not working directly with the RAW file, I'm not going to get the best out of LR3's features.
I have tried raising a call directly with Adobe to ask about this issue. Unfortunatly is not practical as they need direct access to the PC running LR3, which is my home desktop, and I am at work when their call lines are open.
I've attached example output from LR3 and DPP. Both use white balance of 'As Shot', and neither have had any processing done on them. The LR3 shot looks less green that it does at home, I assume thats because I've saved it as a low res JPG.
Thanks for any advise people can give.

Canon DPP output (Same result for Raw Therapee, GIMP and Capture 1)

Strange colour cast in LR3 with Canon G11 RAW

Hi all,
I recently bought Lightroom 3 to work with the RAW output from my Canon G11. The majority of the shots want to process are taken underwater around the UK coast. I'm having an issue with colour casts which I hope someone may be able to shed some light on.
With these underwater shots LR3 seems to import them with a very strong green colour cast, even though, when diving, I set the manual white balance at regular intervals. By comparison, Canon DPP imports the RAW files correctly (what I consider correct), and I get the same correct results with Raw Therapee, GIMP and Capture 1. PhotoShop Elements gives the same results as LR3, but I assume they both use ACR 6.1.
I would expect Canon DPP to be correct as it is processing it's own RAW files, but as the other RAW converters match the Canon output, I get the feeling that my problem is with LR3, or possibly ACR. I've scanned both the Adobe LR forum and ACR forum, but can not see any posts where people are having similar issues to me. I did find several post's saying that LR3's support of the Canon G11 was now finished, maybe it has just been tuned for land based shots, not underwater.
I have tried using Adobe DNG Converter, to no avail, and I have also tried all the white balance pre-sets within LR3. Even the custom white balance picker does not give sensible results, it just changes the shots to a slightly different shade of green.
Playing around with other setting in LR3 can make slight improvements, but it's a slow, shot by shot process, and still does not produce a usable finished product, or even a reasonable starting point for fine tuning.
I have found that I can use Canon DPP to output to TIF, which LR3 then opens correctly, but I feel that as I'm not then working with the RAW file, I'm not going to get the best out of LR3's features.
Is there some particular setting within LR3 or ACR that I have missed ? If not, am I actually loosing detail by converting to TIF before opening LR3 ?
I've attached example output from LR3 and DPP. Both use white balance of 'As Shot', and neither have had any processing done on them. The LR3 shot looks lees green that it does in LR3, I assume thats because I've saved it as a low res JPG.
Thanks for any advise people can give.
LR3 output
DPP output

Thanks for that answer, it shows that I may have some settings which need tweaking.
All the LR3 settings are as standard when first loaded, playing with this bunch of shots (about 20 in all) was the first thing I ever tried in it. I wouldn't even know how to apply split toning even if I wanted to (you probably guessed by now that I'm a new user to this software). All the on land shots I've messed around with import correctly, so it's definitly only the underwater ones.
One thing that I've just remembered, may be important, when I select shots to import in to LR3, the thumbnails look fine. It's only when the import process has finished the green colour cast appears. It's almost as if something is being applied right at the last minute.
I haven't tried to white balance the JPEG. I assumed it wouldn't work with the RAW, it would be the same with the JPEG.
I did process some shots using PS Elements a while ago, and don't remember any stong colour casts in that. They were from shallow fresh water rather than deeper salt water, may make a differeence. I believe the ACR plug in with PSE 8 at the time was in the 5.x range. I did manually upgrade the ACR plug in for PSE 8 to 6.1 after loading LR3. I can try backing that out and seeing if I still get the colour cast.
Hmmm, it's looking more and more like a problem with ACR 6.1. At a guess I'd say it's not interpreting the 'as shot' information correctly, or completly ignoring it.
I'll have a go with white balancing the JPEG when I get home. If you can do it, but I can't, it points directly with a setting on my system. I'll also have a look at uploading the RAW file somewhere.
Cheers

Magenta colour cast added to exported jpg photos

I shoot raw with my Canon EOS 5D and import the raw images to LR. There is no Development preset. Colours in LR look OK on my calibrated monitor - this is not a camera calibration problem as suggested in LR help and knowledgebase; I have tested these solutions with no change. Basic edits are usually about exposure correction or spot removal.
When I export the photos as a jpg files they have a magenta colour cast, sometimes quite strong. LR cannot be used for reliable prediction of what an exported photo will look like.
I checked with Canon Digital Photo Professional. The colour of the original photo shown in DPP is exactly the same as the jpg colours. This makes me think that LR display render is unreliable.
My system is as follows
LR 1.4.1 on PC with XP Pro service pack 2
LR installed on C: with over 80GB free space
LR catalogue on second internal F: with over 34GB free space
Photos on USB drive with over 220GB free space
2GB RAM 2.4 GHz P4 with Dell 2408WFP LCD monitor
LR export to sRGB 80% jpg 1000 pixels short edge (reduced from 4368x2912 pixel)

>I calibrate my monitor with Monaco EZcolor 2.6.5 and an i1 calorimeter from x-rite. I have profiles for day time with natural light and for evening with artificial light. I have also tested the monitor with various pictures for black and for colour rendering.
Excellent! Be aware that I have seen problems on this forum before because of defective colorimeters (a calorimeter is a device that measures heat BTW!).
>I use LR and Photoshop CS2. I use Canon software to download the photos from my camera to sub folder of my own choice then I import them to LR. The colour rendition by LR and Photoshop are identical.
That is a very good sign. If the color rendition between Lightroom and Photoshop is identical, you do not have a bad monitor profile, so we have to think about something else.
>The exported jpg files are uploaded onto a web page at panoramio.com for use on Google Earth. Therefore I view the jpg files with Mozila Firefox 2.0.0.14 and with Google Earth 4.2 The colour rendition by Canon Digital Photo Professional of the raw file is identical to the jpg rendition by Firefox of the web site photo.
Be aware that DPP can be set up to not color manage. There is a preference you have to turn on to make it color manage (you should if you want to trust the color). If you see a difference between Lightroom/Photoshop and an unmanaged browser, it is usually due to the fact that the browser is unmanaged. You cannot trust an unmanaged browser to show you the correct color even on a calibrated monitor. You still should not have a color cast in the neutrals though! Perhaps you should post some examples such as a direct Lightroom export (perhaps simply a link to the panoramio page) and a screenshot of what it looks like on your machine. That could perhaps narrow the issue down.
Do images such as the third image down in the left column (labelled "sRGB Standard RGB 2.2 gamma") on this page http://www.gballard.net/psd/go_live_page_profile/embeddedJPEGprofiles.html look normal (i.e. normal skintones, not too saturated, neutral whites) on your screen?
>I don't know about Firefox 3.0, it has not been offered in the normal auto update. I don't know about the secret setting for Firefox.

Colour cast on a MG 5300

When I print out a black and white photo on my Canon Pixma MG 5300 I am getting a strong red colour cast. Have tried all I know to correct it to no avail so any help would be great!

Christoff:
The photo on the left is the correct color rendition, i.e. the bluish version, right? Do other applications, i.e. Preview, Safari display the photos correctly on your computer?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Yellow colour cast on all photos help!

I have photo taken with a canon 400d with sRGB colour profile set in the camera. However when these or any other photos from any camera have a yellow colour cast. I have the canon Digital Photo Professional software installed as well and when i view these photos in DPP they look exactly as the scene that i captured. Example below.

Can anyone tell how to fix this and have iPhoto show the pictures correctly?
Thanks

Colour colour profiles and JPEG compression mismatch

In preparing images for iBooks I have noticed bizarre behaviours and a number of problems with matching colours.
For example, if a JPEG image all one colour is placed in a gallery widget over a text box, and then the background colour of the textbox is set to the colour of the image by sampling the colour in the image using the colour picker, when downloaded to the iPad the colours will not match (although they appear to in iBooks Author). I presume this must be a bug with the encoding of the JPEG? Or is it a conversion issue between different colour profiles used for the solid colours in iBooks and the sRGB colours that Apple advises using for images?
I have also noticed that if you download a book to an iPad the colour matching between solids and image colours changes radically depending on what monitor you have the computer running iBooks Author plugged into (ie depending on the monitor profile in use). What colour profile does iBooks author use for solids and what for images and why are they different? Is it conversing the solids but not the images, or vice versa, and between which colour spaces? What is the working colour space of iBooks Author? Does it differ depending on the monitor profile? If so, why does converting images to the monitor profile still not result in them matching the solids used in iBooks Author?
In short, does anyone have a clue what is going on with the colour profiles and colour matching in iBooks Author and iBooks on the iPad? They certainly display the most perplexing behaviour I have ever come across.
Giles Hudson

Although you say there is no concept of a colour profile in iOS, the problem is that iBooks Author does recognize profiles, and appears to take them into consideration when downloading images to books on the iPad. For example, an image tagged with an sRGB profile placed in iBooks Author will appear differently from an identical image tagged with an Adobe RGB profile. The problem is, it is not at all clear what conversion is going on, especially when using a monitor with a different colour profile appears to cause radically different behaviour in the conversion. Is it being converted to "Device RGB" that the colour picker apepars to use? What is this Device RGB? The monitor RGB or the iPad RGB?
I understand that iOS supports RGB and CMYK. However, the important question is, which working space does iBooks Author use? sRGB, GenericRGB, Device RGB (whatever that is), Apple RGB, Adobe RGB, the monitor RGB? Without knowing this it is difficult to match solid colours to colours in images (and even arguably impossible due to the JPEG encoding problem I mentioned above).
All this vagueness in colour handling with OSX and iOS makes life very difficult, especially, as you suggest, when things have the potential to change at any minute, potentially wrecking months of painstaking work that has been put into designing books in iBooks Author.

RGB CMYK PDF EXPORT.(colour conversion) Keeping your colours vibrant and your blacks black.

Ive been tearing my hair out for the best part of 14 hours trying to figure out how to keep the closest possible conversion for working with images(rgb in photoshop) right the way through a work flow until exporting to print (having used the image in Indesign). Here is the process I have been trying to get right.
1) working with RGB photo images in photoshop and converting them to CMYK (whilst holding on to as much colour as poss)
2) Importing them to Indesign and retaining the correct colours while working with them)
3) Exporting to high quality print and having all your colours stay 100% the same as you saw them within indesign.
I believe I have the solution so I posted my settings below to see if its the best way of doing things and to help others who might be having the same problems.
The problem
The problem is that there are many different colour models/profiles (both in RGB and CMYK) and each program can effect how the next one handles and stores colour. It can become frustrating knowing where to go in order to set the settings correctly as the combination of things to consider can make it confusing.
I understand many other people have similar problems and finding RGB blacks come out as grey. CMYK spaces get converted from one type to another either from one program to the next or even as things move around one program (causing all sorts of wonderful,colour errors) Plus you have imported colour profiles, working colour profiles and export profiles. All of which can interact and effect each other) So getting it all consistent is key other wise colours change and get washed out.   Especially vibrant colours like greens and blues. they fade etc.
Through sheer trial and error and perciverance I found a combination of settings that worked well for me.
Since I am not an expert I wanted to post up my settings to:
1) see if this is the best way of doing things.
2) Other people may find them useful if they had the same problems I had,
The Solution
In photoshop
Save the photoshop image in CMYK by selecting:
Edit > Convert to prfile.
(in destination space)
select: Euroscale Coated v2   (I think this holds the colours the truest of all CMYK colour formats.)
(in conversion options)
- Engine: Adobe ACE
- Intent: Perceptual.
- Check Use black point Compensation.
(leave all else unchecked)
Save the image ready to place in indesign (place rather than copy and paste.).
In Indesign
edit > colour settings   (make sure you click on the advanced tick box to open more options)
- Working space: =
- RGB: sRGB IEC....
- CMYK Euroscale coated v2
- RGB & CMYK convert to working space.
- Engine Adobe ACE

If you are having problems with fill blacks not coming out as proper black then use registration instead of black from the swatch panel.
The above may seem either obvious to most of you or possibly not the best way of doing things but since the results worked for me and I found them tough to arrive at, it may be of use to others hence my post.
I would like your feedback on this process, have I done something wrong / could do better? If so please let me know. I am keen to improve.

I would copy and paste into InDesign forum. Text should stay 100% black. Any other black (like solid boxes or thick lines), I usually use a rich black swatch I created at 40/40/40/100. Looks 10 times better than just 100% black.

Narrowing cast and widening cast

Hi All,
I want to know what is the use of a narrowing cast and a widening cast in ABAP objects.
Can someone please give an example ?
Regards,
Ashish

Hi,
Check out this link, This will guide you on ABAP Objects

Both narrow and wide casting are related to inheritance.
In Narrow casting, you assign a runtime object of subclass to runtime object of superclass. By this assignment , you can access your subclass by using runtime object of your superclass. But here the important point is that, you are assigning subclass reference to super class reference, so you can only access the inherited components of subclass through super class reference.
Suppose you have a super class lcl_vehicle. it has two subclasses lcl_car and lcl_truck.
r_vehicle = r_car.
In Wide casting, you assign a superclass reference to subclass reference . Before this, you do narrow casting,
Now when you assign a superclass reference to subclass reference. You can access the inherited as well as the specific components of subclass.
taking the same example,
r_car ?= r_vehicle.
'?=' wide cast operator.

Pink colour cast when printing from iphoto

When I try printing from iPhoto to a Canon MG6150 I get a pink colour cast. The preview shows correct colour and I'm running out of paper with my attempts to sort it!
What has gone wrong as everything else seems fine?

Do you get the same results if you print the same photos from Preview? If not then it's definitely an iPhoto issue. If you get the same it's possibly more of a system issue or printer adjustment.
Check the Color Options (Printer) and Color Matching (iPhoto) settings in the print window. You might try tweeking some of them.
Your print window should have something similar.
