Save as 8 or 16-bit from RAW?

Can anyone recommend me saving my RAW files into 16-bit tiff before reproduction?
I shall soon have a number of RAW CR2 Canon-sourced files that I want to process into tiffs and ultimately convert to black and white for repro in a book with a modest 20cm image size. These files will then become CMYK by another party.
What would I gain by saving as 16-bit, making adjustments in CS3 then down-sizing to 8-bit in order to gain maximum detail, as opposed to simply processing straight to 8-bit (seeing as image size is not large)?
If there's a tutorial that best explains 16-bit workflow and concepts, I'd be grateful as it's not something I've learned before PS CS3.
Thank you,
Richard.

Richard,
If you want to be safe, save your tiffs as 16 bpc tiffs from C1 and do your tonal correction and conversion to black and white as adjustment layers in Photoshop. Whether or not 16 bit makes a difference depends a lot on the image content and printing method. If you are printing fine gradated skies or similar things, I would leave everything 16 bit and hand that off to whoever is doing the conversions for you. The chances are that it won't make a difference. Just remember that even 16 bpc files can posterize too if you push them far enough, and digital camera files are much more prone than scanned film.
There is almost no reason to use psd files anymore. Tiffs do just about everything including saving larger files, and zip compressed tiffs are almost always smaller, a lot smaller on disc, than layered psd files. My feeling is that if there weren't so many legacy psd files out there, Adobe would just as soon drop support for that format.

How to save 12-bit RGGB RAW in 10-bit log Adobe DNG?

I am implementing a vision project, and want to save disk space by converting the 12-bit linear raw files to 10-bit log Adobe DNG files.
I went though the DNG document but could not find the formula or matrix to convert from 12-bit linear RAW to 10-bit log DNG.
Can someone kindly offer these details ?
Cheers!

I'm glad you mention the issues with packing bytes.
I had 12-bit RGGB raw saved as a DNG, but the colors were off.
The byte order in Adobe is different and seems to be undocumented.
I had not problems with 8-bit RAW converted to DNG.
https://dl.dropboxusercontent.com/u/9906333/12-bit.zip
I have code that writes packed data, but it would be nice to access the way that DNG expects the packed data to be written.
For 10-bit, I would be looking at 4 pixels in 5 bytes. I am unaware of any packing that would allow this, and if Adobe DNG actually supports this.
At least with 12-bit, 3 pixels in 2-bytes, there seems to be support - however, the actual pixel order is unknown.
I will go through the Linearization tables in the DNG spec now.

ACR and Stitching From RAW Files

I see something peculiar happening on recent stitches.
I have say, three frames to stitch from RAW. One frames a little overexposed, so I open in ACR, drop the exposure to compensate and save. Then I open all three frames in Photoshop>Merge as RAW files. When the adjusted frame shows up, the adjustment is ignored.
I can fix this by opening the other two and do a very slight change to them, save, then all three show up as expected, the bright one matching the other two close enough to get a uniform stitch.
Now I am doing this as a quick test of the stitch, to see if I really am interested, and if so, I go back and open all three in ACR and make the corrections. After doing all three, I can uncouple the bright one and tweak its exposure, then save and stitch, no problem.
Is this normal?

I am selecting the images after making the raw adjustments in Bridge and selecting Photomerge under the Tools.
I haven't experienced this either until now. The difference is that Iwould always select the images and open in ACR first, and run the corrections synchronized. Occasionally, one would be off enough to require special tweaking so after the synch corrections, I would select it, correct it then click Done. Getting a bit lazy, especially with many panos waiting, I do a quick test and in this case, only one of the three needed tweaking. Running Merge as above ignored the tweak.
Try it yourself. Pick some images to merge that have not been through RAW, and tweak one only in ACR. Click Done then Photomerge from Bridge under Tools.
I've done this twice now, after exiting Bridge and Photoshop first.
Make that three times

How do I process multiple files and turn them from raw to jpeg

How do I process multiple files and turn them from raw to jpeg. Ive tried and it seems to go through the files but doesnt seem to process them or store them in the selected folder

Yes that was the first thing I did. Then I used the process multiple files and selected a new folder to put them in and selected use open files and selected to turn them into jpeg. The images flash on the screen like they are being processed, but the folder never appears in library. Is it possible because there are a couple 16 bit files open that this corrupts the task. Do I need to create the folder first. Will elements not create the folder on its own.
Thanks Vince

Digital photo professional - export JPG from RAW

Hello!
i have a problem with program Digital photo professional, when i want export images from RAW format to JPG.
The problem is, that quality of image is much more worse, then in RAW format in DPP. JPG looks blurred and fuzzy.
IMAGE LINK:
Please check image, on the left side is print screen from RAW in DPP, on the right is exported JPG from DPP.
I want export JPG with the same quality as i see in RAW
Is there anybody to help me?
Thanks a lot.
Vit

1. open *.CR2 (raw file) in DPP
2.file/convert and save
3.type of file - EXif JPEG (JPG, JPEG)
4.image quality 10
5.output resolution 350dpi
6.check - embed icc profile in image
There are not another settings, so i dont know, why has exported JPG so bad quality...
When i open *.CR2 file in PS5, i see the same bad quality as exported JPG from DPP, but i read, that PS5, cannot
open CR2 file in best quality, because PS5 doesnt have all function, that have DPP.
I tested it on two PC, so problem is not only on my PC...
Thanks.

JPEG is corrupted when saved in B&W from RAW

Hi,
today I ran into this issue when saving black and white pictures from Raw file.
Camera RAw 7.3 opens normally just like always and lets me save picture in color.
It lets me save picture in BW, but the JPEG tha comes out is corrupted file that looks like this (see below):
When i try to open that corrupted JPEG in Photoshop 6 I get an error message saying:
"The embedded ICC profile cannot be used because ICC profile is invalid. Ignoring the profile. "
After clicking "continue" on the error message I am able to load the picture in PS6- however when i go to Image>Mode picture is appearing a RGB, not a Greyscale as it should be.
Any ideas why this is gappening an how to fix it?
It seems that new Raw Plug In is casuing it- I uninstalled Photoshop, installed Camera Raw 7.2 and its seemed to be OK. As soon I upgraded to 7.3 I get the same error.
is there a way to downgrade it to 7.2 without uninstalling PS6? Manual download and rewriting 7.2 over .3 doesn't seem to work.
Thanks!

I can confirm the issue...it's been reported. In the meantime, actually opening the image into Photoshop and saving as a JPEG works...you could simply open the image into Photoshop to save as JPEG or adjust the images in ACR and then use Image Processor from Bridge. And no, you can't easily install 7.2 over 7.3. Since both are not currently offered as seperate downloads (updater only) you would have to find the 7.2 download...the Mac and Windows downloas are mentioned in this thread.

Aperture Exporting JPEG's from RAW: file size and quality questions?

Hey Everyone,
So, I'm using Aperture 2 and I've got some questions about exporting from RAW to JPEG. I shoot with a Nikon D70 so original RAW files are 5-6mb in size. After doing some basic post processing when I export the pics at "full size" with picture quality of 11 out of 12 then the resulting JPEG is about half the file size of the original RAW file. For example a 5.6mb RAW becomes a 2.6mb JPEG. The resolution in pixels per inch and and the overall image size remain unchanged. Have I lost picture quality due to the exporting JPEG being smaller in file size?
My friend who works with me prefers to edit in Photoshop and when he follows the same workflow his saved JPEG from the identical RAW file in Photoshop is minimally smaller in file size, say 5.6mb to 5.3mb. He's telling me that my Aperture edited photos are losing quality and resolution.
Is he right, are my pics of lesser quality due to being a smaller file size? I've always been told that the quality of a picture is not in the mbs, but the pixel density.
I've bee told that Aperture has a better compression engine and that the resulting files are of the exact same quality because the PPI and image size are the same. Is that what explains the much smaller file sizes in Aperture?
I tried changing the picture quality in the export menu to 12 out of 12, but the resulting JPEG then becomes larger than the original RAW at over 7mbs.
Can someone please help me understand this better? I don't want to lose picture quality if that is indeed what is happening.
Thanks in advance for your help.

JPEG is a "lossy" file compression algorithm. Whether Aperture or PS, *every time a JPEG is saved some loss occurs*, albeit minimal at the 11 or 12 level of save, huge losses at low save levels. Some images (sky, straight diagonal lines, etc.) are more vulnerable to showing visible jpeg artifacts.

*Both of you are losing image data when you save to jpeg.* IMO the differences between the apps is probably just how the apps work rather than actually losing significantly more data. The real image data loss is in using JPEG at all!
Is he right, are my pics of lesser quality due to being a smaller file size?
I doubt it.
I've always been told that the quality of a picture is not in the mbs, but the pixel density.
The issue here is not how many pixels (because you are not varying that) but how much data each pixel contains. In this case once you avoid lossy JPEG the quality mostly has to do with different RAW conversion algorithms. Apple and Adobe both guess what Nikon is up to with the proprietary RAW NEF files and the results are different from ACR to Apple to Nikon. For my D2x pix I like Nikon's conversions the best (but Nikon software is hard to use), Aperture second and Adobe ACR (what Photoshop/Bridge uses) third. I 98% use Aperture.
I tried changing the picture quality in the export menu to 12 out of 12, but the resulting JPEG then becomes larger than the original RAW at over 7mbs. Can someone please help me understand this better? I don't want to lose picture quality if that is indeed what is happening.
JPEG is a useful format but lossy. Only use it as a _last step_ when you must save files size for some reason and are willing to accept the by-definition loss of image data to obtain smaller files (such as for web work or other on-screen viewing). Otherwise (especially for printing) save as TIFF or PSD which are non-lossy file types, but larger.
As to the Aperture vs. ACR argument, RAW-convert the same original both ways, save as TIFF and see if your eyes/brain significantly prefer one over the other. Nikon, Canon etc. keep proprietary original image capture data algorithms secret and each individual camera's RAW conversion is different.

"Convert" from RAW to JPEG?

I normally shoot in RAW so I have the power to make more accurate corrections, if needed. 90% of the time I don't need the RAW image after I've made adjustments, however. Here's what I would like to accomplish using Aperture 3:
-Import RAW images
-Make adjustments to photos as needed
-"Convert" all images 3 stars and below to JPEG and replace (i.e. DELETE) all associative Master RAW images.
What I've been doing is exporting all the images to my desktop after I've made the adjustments, delete all the photos out of the album, and re-import the JPEG images into the album.
Obviously, this is not a very efficient method and a "convert" option would be nice to use if it's present.

The answer is 'No'.
There is no way of doing what you want, many of us in the real world would love that. I for one understand your question from the stand point of I don't want to save every image I ever take in RAW because of the file size.
If you camera can support taking photos in RAW+Jpeg, then there is a route to take that is discussed in this thread:
http://discussions.apple.com/thread.jspa?threadID=2375402&start=0&tstart=0
In essence, with RAW+Jpeg, you take a photo in both formats. Note the Jpeg version captures the photo with your camera settings intact (i.e. Creative mode settings, saturation, picture style 'stuff' as an example).
You import (have to choose in import, bottom right corner...outlined in above thread) and then choose which you want to keep Raw and which to keep in jpeg.
That is, for the moment, the best route to take....if you can. Not all cameras offer Raw+Jpeg.
Best of luck! I know your pain!

Saving from bridge and converting from raw to jpeg

why can I not convert from raw to jpeg in bridge (camera raw) and save to a location different from the original

Yep sure can.
In bridge select your picture(s) then edit in camera raw.
In camera raw look in the bottom left of the camera raw dialog box and you will see a save as button.
This will allow you to save your raw files as jpg, tiff or pngs.

Okay, I've got some coding off a site that looks like it will do what I want. It's quite a robust applications which will do more than I need but as long as it does at least what I want, i could care less. As it will extract files from the datastream for me, it is going to save them to disk.
I believe I have to specify a directory to save it to. I believe this is the line I'm going to modify, so assuming that's the case, how do I specify a directory here:
private File fileOutPutDirectory = null;
Do I have to use absolute paths or can I use relative. Also, what directory construct is expected by java? Anyone with an example of what urls are supposed to look like in this case?
Thanks,

Highlights disappear from RAW files

I have a bunch of raw photos that I took from a dinner party. When I use Adobe Bridge (Windows Vista 64)to view them, the raw files look great. If I double click to open one in camera raw and then make no changes at all, just click to save it as a jpeg with the highest quality, the catchlights in people's eyes and any sparkles on jewelry nearly disappear. Do I have something set wrong? I know you lose detail going from raw to jpg, but it should not lose this much. The catchlights nearly fade out completely.
Thanks for any advice.
Jean

Hello,
Thanks for responding. I hardly ever accept the default ACR settings. My problem was that I was NOT making any changes to the RAW file. All I wanted to do was to convert it to a jpg. I think my problem was with Adobe Bridge, though, because once I opened it up in Photoshop, it looked much better, even though it looked horrible in Bridge.
In fact, now Bridge is giving me a different problem. After I save a file as a jpg, it shows up in my Bridge browser. If I click to view it in bridge, the bottom half is completely obliterated with horizonal colored bands. (Looks like the graphics card dying, except it's only in Bridge.)Only random files this happens with. If I open that same file in any other program, it's fine. Aargh!

Is there a PS setting where it can read my Canon Mark 3 5D's monochrome setting so that the files will also appear in the same monochrome structure (instead of appearing in colour as it is now when i open in PS, not even monochrome)? Or do I have to change from RAW each time to Monochrome within PS (even if I have set up for Monochrome in my 5D)?
1. Basically I am taking photos with a monochrome setting with my 5D and the screen shows monochrome.
2. when i import this onto my computer and open with PS, it opens in colour.
3. when I change this to Monochrome in PS. (It cannot read my monochrome setting with my preference of the greyscale mix when I viewed it on my 5D)
4. my question is: is there a way so that PS can read the monochrome setting from my 5D and display the same monochrome setting as my 5D instead of a different one from PS.

you need camera raw 6.7 or better.
