Reflections and shadows

Can the Forum members give me any links or tips on creating light reflections and shadows? I'm restoring a photo of my old street rod and I have painted it using layers and all the body lines show through but I need to add light reflections to make it look glossy and real. Barbara Brundage are you there? I looked in your book but maybe not in the right place. I use white, the blur tool and layers to create reflections and black and same for shadows. Thanks to all that reply

Web Site Maestro. It optimizes and uploads. It also has a "smart handling" feature that that allows you to process the changed files only.
Very fast and efficient.

Aperture sometimes slow import slow reaction on highligts and shadows

1. Aperture sometimes, one out of three times perform a slow import from a compactflash card. Normally 10 images (nikon d-200 10 mb) in less than a minute. Sometimes the same ammount takes more than 5 minutes. Reconnecting the cardreader on the front usb connection solves the problem.
2. Using the sliders on highlights and shadows, the adjustment of image takes a little time, no instant reaction.
3. Aperture is installed on a 250 gb hd (first) (standard installation version 1.5.2). The data is installed on a second 500 gb internal drive. Drives never go to sleep. 4GB internal ram. Video card 7300 GT.
I have talked to different people about this performance issue and got different answers, which range from:
a. This is the best performance with aperture with the current system. If you want more buy a better video card.
b. Your video card is bad, mainly the vram. Replace the video card (warrenty still applicable).
Any views and advice from this forum?

Mac OS X 10.4.9 to boost image import speeds
By Prince McLean
Published: 09:35 AM EST
Apple this week dropped yet another pair of pre-release Mac OS X 10.4.9 builds on its developer crowd, inching the software closer to a public release.
The diligence with which the Cupertino-based company has been refining the software may signal that Mac OS X 10.4.9 will be the final maintenance update to Mac OS X 10.4 Tiger before attention is drawn solely to Leopard.
As was the case with prior seeds, developer notes accompanying the latest builds -- 8P2132 (Intel) and 8P132 (PowerPC) -- are said to reflect no known issues with the software.
People familiar with the latest pre-release say Apple notes just one significant change since builds 8P2130 and 8P130 were issued last week, specifically a bug fix to ImageIO that was affecting image import speeds.
This is from Apple Insider.

I have upgraded Apple Aperture from version 2 to version 3 and I'm having a problem with the "Highlights and Shadows" adjustment. According to the user's manual, I should have access to an advanced disclosure triangle which would allow me to adjust mid contrast, colour, radius, high tonal width and low tonal width.
If anyone has any suggestions as to how to access this advanced section, I'd be most grateful.

Hi David-
The advanced adjustments in the Highlights & Shadows tool were combined into the "Mid Contrast" slider in Aperture 3.3 and later. If you have any images in your library that were processed in a version of Aperture before 3.3, there will be an Upgrade button in the Highlights & Shadows tool in the upper right, and the controls you asked about under the Advanced section. Clicking the Upgrade button will re-render the photo using the new version of Highlights & Shadows, and the Advanced section will be replaced with the new Mid Contrast slider. With the new version from 3.3 you probably don't need the Advanced slider, but if you want to use the older version you can download it from this page:

Print quality for light gray gradients and shadows

Hello all,
I am putting together a single page flyer which will have light gradients and shadows on the objects.
Think Apple-ish light grays and shadows...
I would like to get an opinion here from someone in the know as I am much more of digital guy than print.
1) What is the lightest gray I can work with that would print well?
When setting up the CMYK color should I simply set it at say 10% 10% 10% 10% or is there some better mixture for light gray gradients. i.e. slightly blue for example, or rich black mixture.
2) When creating the gradients in illustrator, should I go from the gray to transparent or is it better to set up a gray to white gradient?
Finally,
When creating my supporting images with the shadows and gradients, would it be best just to create them in Photoshop and place them in my illustrator document and leave Illustrator for the text alone?
Thanks in advance, I really appreciate your help

Let's assume you are working in Illustrator. Here's my advice:

"I would like to get an opinion here from someone in the know as I am much more of digital guy than print.

- It should not be necessary to use 10% across the board. It comes down to how you want the shadows and gradients to appear. You ask what is the "lightest" Gray. That depends on the press and paper. Let's also assume you are planning for high end offset on a high end glossy "White" stock ( paper ). A 10% Black is fairly reasonable, but you could plan for 5%K ( again, depends on press and paper ). A nice warm Gray could be achieved with 7.5%C, 7.5%M, 7.5%Y, 0%K; a nice cool Gray could be achieved via 2.5%C, 0%M, 0%Y, 7.5%K. I would cross check a Pantone Process Color Guide for a reasonable choice. Do not rely on the monitor.
2) When creating the gradients in illustrator, should I go from the gray to transparent or is it better to set up a gray to white gradient?
- It should not be necessary to set your gradient to transparent. A typical scenario would be K > 0W; only specific requirements demand transparency.
Finally,
When creating my supporting images with the shadows and gradients, would it be best just to create them in Photoshop and place them in my illustrator document and leave Illustrator for the text alone?
- That depends on the file, the background, and a few other considerations. The key to shadows and gradients in Illustrator is they be applied as part of the final step in the file prep process. If you create the shadows, for instance, in Photoshop, the end file size may end up larger than you anticipated. And, the shadow would be resolution dependent ( less flexibility ).
Thanks in advance, I really appreciate your help"
Before you get started with your file, contact the print vendor to find out what type of press and what type of paper they plan to use on your job ( of you haven't already ). Don't forget to set your document resolution in Illustrator ( assumed ) and the Raster Effects resolution. Another important thing to remember is nail down the actual Gray ( i.e., lookup in Pantone Process Color Guide printed on the paper type you plan to use on press ).

Preview highlight and shadow clipping mask in second monitor

Hi, I'm new in the forum and just starting with the new LR3. I have a question about to preview highlight and shadow clipping in the second monitor, becouse I can't check the mask clipping in my second monitor as in the LR2... Is there a possibility to change it to preview the mask in the second monitor?
Thanks and regards
Daniel

Yeah, thanks.... but I mean that when you are in develop mode and you try to see the highlight or black clipping mask, red or blue, now in LR3 only appears in the main monitor, not in the second monitor as well like in LR2... Maybe I'm not explaining very well the difference...

Satellite L350D-216: Green lines, dots and shadows.

Hello all.
About three days ago, I purchased a laptop (Toshiba L350D, released about July '09 I believe) second hand on a good deal.
I turn it on today, to discover a series of weird green lines, dots and shadows, most of which make areas of text hard to read.
[http://i16.photobucket.com/albums/b30/philkensebben/Capture4.png|http://i16.photobucket.com/albums/b30/philkensebben/Capture4.png]
You can see them to the right of words and if you look close enough, also surrounding various letters in the Google logo.
[http://i16.photobucket.com/albums/b30/philkensebben/Capture2.png|http://i16.photobucket.com/albums/b30/philkensebben/Capture2.png]
Not especially clear here (sorry), but the greyed out words in the address bar are very ghosted.
Also, it appears to have replaced solid areas of colours like grey, with a 'dotty' green colour.
[http://i16.photobucket.com/albums/b30/philkensebben/Capture1.png|http://i16.photobucket.com/albums/b30/philkensebben/Capture1.png]
It appears this issue has also spread onto video, where areas of green are now appearing at random points.
[http://i16.photobucket.com/albums/b30/philkensebben/Capture5.png|http://i16.photobucket.com/albums/b30/philkensebben/Capture5.png]
I have updated the display drivers with the latest ones available from here, which sadly made no difference.
Any advice on why this suddenly decided to happen and how to get rid of it would be appreciated, I use the laptop for Photoshop and as you can imagine, having areas of green and shadows is rather off-putting when i'm trying to work.

If an external display (a monitor plugged into the laptop) shows no sign of the fault you can presume the the graphics chip is not at fault, after all it's working fine on the external monitor! If this is the case you don't need a new motherboard. I have repaired many graphic chip faults on laptop motherboards, and find that toshiba are usually quite good at not getting this type of fault.
I would suggest that the problem is more likely to be related to the cable that connects your screen to the laptops board (this is if the lines are vertical). Try moving the screen about on it's hinge and see if the problem goes, you can also slightly twist the screen and see if the problem goes. If you are not confidant to do the job yourself take it to a confident repair shop and they will be able to diagnose the problem. If the lines are horizontal it may well point to a capacitor problem which once again is not a new motherboard, just a decent repair centre which can identify the fault and repair it by replacing new capacitors on your board.
Hope this helps.

Reflection and RTTI

I need to create references to new objects of leaf classes from the root class in a class hierarchy. I am not sure how to do this. I have considered reflection and RTTI, but with no success.
I have a hierarchy of classes with several levels. Each class has methods that overrides the methods it inherited. Each of the classes at the bottom of the hierarchy, has a different code for the methods inherited. The root class does not know the existence of the classes at the bottom of hierarchy. The root node receives a "token" from an external source. Based on this "token" (it is a String) it needs to generate a reference to the Object of the class for the "token". Then the root class can apply one of its methods on this reference. This application of method needs to give different results for different references.
I tried the following approaches. I applied Class.forName(token) to get the Class of the "token". Then I used newInstance() on this Class. An Object refers now the instance. I needed to type cast this object to apply my method to get the desired result. Since I do not know the type of the object, and the class of the object is not loaded at the compile time, I decided to use reflection. I applied getConstructors(), getClass(). Still the problem of type casting to the type of the required class remains unaddressed. Can anyone help? Thanks!

        create("Cat").vocalize();
class Dog extends Animal {

Reflection and generics

Hi all:
I am working with the generic and reflection stuff. Well the problem is that in one of my clases I have a data
private Vector<nAryNode<T>> childs;
.....where nAryNode<T> is a class I created using generics.
Now when I want to initialize my childs variable, well the easy thing to do is:
childs = new Vector<nAryNode<T>>(3)But I want to initialize it using reflection and my code is:
        Class v = Class.forName("java.util.Vector");
        Class[] argVector = new Class[] {int.class};
        Constructor consVector = v.getConstructor(argVector);
        Object[] arguments = new Object[] {new Integer(n)};
        childs = (Vector<nAryNode<T>>)consVector.newInstance(arguments);Finally when I compile I got the annoying warning message
nAryNode.java:29: warning: [unchecked] unchecked cast
found : java.lang.Object
required: java.util.Vector<nAryNode<T>>
childs = (Vector<nAryNode<T>>)consVector.newInstance(arguments);
^
Well my program can run, but I would like to make disappear that message. Please if you have any suggestions for me, it will be great. Thx

AFAIK, there is no solution to this currently because arrays of generic types are not allowed. Therefore "consVector.newInstance(arguments);" return a Vector and cannot be made to return "Vector<Integer>" (or whatever)

Java reflection and singletons

Using java reflection and singletons .. anyone seen this being used?

I've solved it
I had a singleton but then it turned out i had to use reflection instead, i tried to used reflection on 3 methods but the session value within was null upon the second method call. Relfection was re-creating the Object.
Sorry for wasting your time.

User set cliping points for Highlight and Shadow

OK I know Lightroom 3 is currently available as a Beta version and is not complete and there may be more features to come.
But
Wouldn't it be nice in the develop module to set the point at which you get clipping warnings for highlight and shadow.
I ask this as a lot of my work goes straight out for repro, and it would be usefull to be able to set the highlight to say 90-95% and the shadow to about 15-20%.
OK I know I can run a tool over the image and see what the percentage is, but it would be a lot esier if I could set my own limits and just watch for the red and blue "blobs"
Just a sugestion

I too find the FTP server implementation to be sorely lacking in OS X Server. There is no option to share out only the designated FTP root folder without showing the other share points. It seems impossible to lock down subdirectories to specific users with letting them see the contents of the root directory. Maddening!
I'm looking at other FTP server options. Rumpus comes highly recommended, but I also just found CrushFTP which also looks intriguing, especially its option to integrate with LDAP - something that Rumpus does not do. CrushFTP is also significantly less expensive.

Are highlight and shadow clipping must be avoided in any image?

Are highlight and shadow clipping must be avoided in any image?
Because in some cases, let's say, night scene, usually has many black pixels in the sky. Which perform nice contrast against the colorful signs.
Please check the attached image for reference(01.tif).
I know there's nothing in the sky, so I would like to keep all the pixels to be clipped. Is this right?
Some of my students says that other instructors told them to keep all the pixels in the histogram.
But I tell them it depands on how would you like your images to show. Am I correct?
As the attached image, it's impossible to pull the black pixels back to the histogram and I think it's acceptable in this case.
Let's see the 2nd case(02.tif), this image has highlight clipping in the clouds.
I like the way this image looks, which looks like a watercolor painting.
If I pull the white pixels back, the image will change a lot and I will get a very dark overall.
My question is, is it that important to keep your images without having highlight or shadow clipping?
This is not apply to any image, right???
THANK YOU

For a more in depth discussion of clipping, it should be noted that clipping can occur in either the raw file or the rendered white balanced file. In the latter, it can take the form of luminosity clipping or saturation clipping. Saturation clipping occurs when the chosen color space is too small to accommodate saturated colors at a high luminance. In ACR, saturation clipping is indicated by a colored line or shoulder at the right of the histogram. The remedy is to use a larger color space. Luminosity clipping in ACR is indicated by a white line or shoulder at the right of the histogram and the remedy is to adjust exposure or use highlight recovery.
Examination of the OP's histogram shows a yellow line at the right, indicative of saturation clipping of the red and green channels. The OP could try a wider space such as ProPhotoRGB.
Here is an image of a a flower rendered into sRGB using the ACR defaults and the Adobe Standard camera profile. It appears overexposed and the yellows (actually reds and greens) are clipped as indicated by the yellow line at the right of the histogram.
The raw histogram (produced by Rawnalize) shows that the image is well exposed. The red and green channels are just short of clipping. The image appears overexposed with ACR, since ACR uses a baseline exposure offset for the Nikon D3.
However, when white balance is applied for this daylight exposure, the red channel is multiplied by approximately 2.21, and this should result in clipping of the red channel. This did not work exactly as expected with ACR, so I used Iris (a freeware astronomical program which allows extensive control of the conversion process) and examined the histogram of the resulting image in Photoshop. Note that the green channel is just short of clipping, as expected and that the red channel is clipped.
To avoid clipping with the white balance in ACR, it is necessary to use negative exposure to offset the red white balance multiplier. I chose to use a bit of highlight recovery as well to tone down the highlights while maintaining a pleasing value for the midtones. Here is the resulting preview with rendering into ProPhotoRGB.
In this case, I was able to avoid clipping. However, when the image is printed or viewed on a display with a limited gamut, some clipping would undoubtedly occur.

Aperture to export photos either TIFF or JPEG files, highlight and shadow transition has obvious faults, this problem solved!?

What problem?
You will have to be _a lot_ more specific if you'd like responsible feedback.
I export thousands of TIFF and JPG files a week with no obvious faults.

Highlight and Shadows Problem

I use a 2GB Imac Intel 2 Ghz If i set Highlights and Shadows in the RAW window to anything above 0.0 when i use the loupe to view close up the loupe isnt as responsive its like the adjustments are eating up all the CPU time, the loupe usually has fluid movement around the image, but not if i enable Highlights and Shadows?
Any ideas?
Cheers

yup. the hilites/shadows settings eat a lot of processing power.
Cheers,
Karl

Highlights and Shadows Adjustment Panel

Hi
Since upgrading to 3.3.1 yesterday, I have lost the Advanced segment of the Highlights and Shadows adjustment panel.
It will show up on photos which had been previously edited using this segment, but not on photos which have not been edited.
Photos are on an external drive.
Any fixes?

See Kirby Krieger's Thread:
How to not miss that olde-tyme Highlights & Shadows 7-slider Brick
Basically you use an image, that still has the Version 3.2 Highlights & Shadows adjustments and create an adjustment preset (effect) from this image. Then you can use the advanced controls again for all images.

LR 4.4.1 crashing on iMac osx 10.8.5 when using exposure and shadows sliders. Will not restart with out resetting surge protector. Worked perfectly for 1.5 years with upgrades to 4.4

Hello,
Thanks for any help you may have. LR 4.4 worked perfectly on iMac 27' OSX 10.8.5 for 1.5 years until October this year when shut downs began when making adjustments on primarily exposure and shadow sliders. Unit would not restart unless rebooting surge protector(s) after 10-15 minute wait. Apple replaced main board and cleared disc. Back-up and LR 4 reloaded and updated to 4.4.1. New surge protection or direct into receptacle makes no difference and shutdown happens immediately upon slider movement. Any suggestions or self checks an old guy can possibly do? It is Educator/student version.

Hello and thanks for the reply.
The entire computer shuts down and will not restart without a reset of the new (and previous) surge protector or if plugged directly to the wall receptacle anywhere from 30 minute to overnight reset before on button restart will work. Other than slider adjustments on LR, it has only shut down one other time when loading photos via USB 3.0 cable to LR. All images from camera are in RAW. Apple tried to replicate this earlier this week with LR but could not read anything other than an increased usage on one of the diagnostic meters when the sliders were moved quickly from side to side.
Other computer functions are normal and rarely used except for e-mail, web search, and 90% LR. Plenty of memory in reserve.
Considering two upgrades (1) LR 5 to get new camera profiles (Pentax K-3)
(2)Yosemite OSX if it would help the LR4.4 or LR5 actually behave
Hope this helps illustrate the dilemma and thanks for your support.
