CS3: TIFF to JPEG?

[snmichaels]

I've got a weird problem. I convert my RAW files with CS3, edit and save as TIFF. I then save that file again, but as a 1200px JPEG for emails and posting on Flickr. The problem is that the TIFF file looks the same as I saved, but when I open the JPEG file, it looks like it has lost some saturation or something. It's VERY different to the TIFF file. It only does this with CS3, not with DPP. Any help or suggestions?


Thanks.

what color space are you saving your jpegs? maybe you have a different color space for tiff and that's why you are seen color difference, also you have to understand that jpg it's a compress file and it does change the integrity of the image. I see that when I download my files from my card, when I shoot RAW+jpg in bridge the images look totally different, the jpg files look more saturated and with more contrast than the RAW files, it has to do with the compression of the jpg file.

I had an odd problem with JPGs with CS3. What type of JPG are you trying to make. I was getting odd results with JPGs when I used the progressive method. When I switched to the default method, everything cleared up. I don't know if this is the problem you are having, but its worth checking.

Edit: Convert to Profile: sRGB before you save as a JPG.

When I uploaded the TIFF file to Flickr, it converted to JPEG and looks the same as using CS3. I know the JPEG usually saves with higher sat and contrast, but after using CS3, it's the opposite. It is in RGB, but not sRGB; how do I change that?

The following are JPEGs: The first is from DPP (a straight conversion) and the other after a few CS3 tweaks. The image does NOT look like this when editing in CS3; it's only after saving and opening the file with Windows Picture and Fax Viewer.

Make sure you have set mode to 8bits before you convert to sRGB and save as tiff?

[snmichaels]

It's already in 8bit and I save in TIFF and it looks the way I want it (the way in looks in CS3). It's when I save it as JPEG and view it with Windows Picture Viewer. The TIFF looks warmer with better skin tones. TBH, I mostly only notice it with portraits. The JPEG image just looks like the person has become ill all of a sudden. It's a little difficult to show because I can't post the TIFF image to show how I wanted the image to look. I'll try to save as TIFF then convert to JPEG with DPP and see if that helps.

Anyway, I'll keep playing with it. I still don't see sRGB, only RGB; is there a difference?

[snmichaels]

I tried converting to JPEG from TIFF using DPP, and that seems to work much better; though a little sharpness was lost initially. I'll play with it more later. It's midnight here!

Sami - its more that bits,
s RGB is "generally" best for people on web - but not always !!
a RGB is "generally" best for landscapes and print - but not always !!!
You can convert it or save for web - its best to open in camera raw even if jpeg.
A. Adams said " there are no rules - only good photos" !
The real true color balance is prob between the two spaces and WB Hue Tint Contrast sat etc etc will be more powerfull than any color space or print profile.

Hi there. Well, I still couldn't get it right with CS3. So what I've done is save in CS3 as TIFF and then use DPP to convert the edited TIFF file as a smaller JPEG for web use. That seems to work perfectly.

Also, I still don't know how to change from sRGB and aRGB?! When I go to mode, it just says RGB; how do I select between the two?

Thanks.

Don't use mode. Instead go to Edit > Convert to Profile... In the dialogue box, select the profile you want from the drop down menu.

Also, you didn't ever say which Format you are saving to for your .jpgs. When you do File > Save as..., you then select .jpg as the format to save. This brings up a .jpg options dialogue, and here there are three format options. I had a problem similar to yours when I was saving using the "progressive" format. It went away when I switched to the Baseline Standard format.

snmichaels - In CS3, when you open ACR to edit your CR2 file to save as TIFF, at the bottom of the dialog box you will see an underlined description of your file. It is usually between the "Save Image..." button and the "Open Image" button.

On mine, it would typically say:

sRGB IEC61966-2.1; 8 bit; 3888 by 2592 (10.1MP); 240 ppi

If yours starts with "Adobe RGB (1998)" or anything other than "sRGB" then that is your culprit. Click on the underlined text (its a link) and change your color Space to "sRGB".

My guess is that you converted to TIFF as aRGB and then when you went from TIFF to JPEG you either left it as Adobe RGB or converted it to sRGB.

When you go from RAW to TIFF via Adobe RGB (or anything other than sRGB), you've locked the TIFF into having a specific gamut of colors larger than sRGB. Adobe Bridge and Photoshop will correctly show those colors to your screen. But, all Windows and most web browsers (Windows, Mac, etc) will default/convert to sRGB regardless of the colorspace in the image file. sRGB has a different and smaller set of colors than Adobe RGB and you end up losing different colors in addition to being squeezed out of colors. Hence the dramatic change in your 2nd photo.

It's best if you're going to the web (and most print places) to start your workflow in sRGB. RAW -> TIFF (sRGB) -> JPG (sRGB) to minimize the loss in colors.

There are a couple of more places to check your profile settings:

Bridge -> Edit -> Creative Suite Color Settings -> "North American General Purpose 2" or
Photoshop -> Edit -> Color Settings -> "North American General Purpose 2"

with RGB set to "sRGB IEC61966-2.1"

I hope that helps :)

Thanks!! Absolutely right; that solved it!
