Turnstile Swipe

Yes, I realize that I posted this one before, but it was in b&w.

On a technical color note - I am having trouble getting the web image colors right.  By right, I mean what I see in Photoshop or Lightroom. (Monitor calibrated.  Prints with profiles for particular paper, correct).

So I’m working in colorspace: Adobe 98, and then I convert the file to sRGB.  With the “Windows” proof selected, it looks correct.  With “monitor” proof, it has a reddish cast, and is more saturated, or maybe just darker.  And when I do “Save for web” and do the “2-up” thing so I can compare the source and destination images - the web destination image is definitely too red.

What I’ve done is to create an action to put some more cyan into the web image, and that is closer to what I see in Adobe RGB.  So what’s the trick?  Do I have to be working in sRGB as my workspace in PS so that it doesn’t change when the jpg is created for the web?

If I change my workspace color preferences to “monitor” - then “save for web” output matches the photoshop source output exactly.  But that’s not good for printing.

Anyway - I’m sure you have the solution.

I have gone back and forth with the same issues for years now… I have never had much luck with “save for web” jpg’s, it just compresses and strips to much of the data off the image for me. What I have been doing lately is doing a batch image process and changing everything to the sRGB color profile after I have finished everything and I am ready for it to post to the web.

I have tried it with both the raw nef’s (from a nikon equip) and with the jpg’s right out of the camera. I am shooting RGB 1998 in the camera, but that never looks good (to me) going right to the web. I did a post on the color profiles on my blog a while back, just because I was trying to get this issue right… but… I don’t think in the end, there is a “right”. I have even used a pretty extensive monitor calibration software/hardware but, in the end, every single computer that looks at an image on the web is going to see it in slightly different colors (that we didn’t intend to be there).

So, after processing my files, I just go to the image directory, then run in Adobe bridge I run >> tools > photoshop > image processor. The run the batch to convert all completed edits to sRGB. It will still end up just slightly different. The image in this post looks great, even tones, great white balance control and no over run on the redish colors to me.

I feel your pain though… one single image can take on the look of 10 completely different images with the white balance, camera picture controls, color space profiles, and 100 other things. All that to say, I am pretty much doing the same thing. Sometimes I like the results, sometimes I don’t. Good luck, great post.

Scott - thanks. Yes, I have a similar PS action (which is how the image above was created). It’s good to know I’m not alone with this. I just wanted to make sure that there wasn’t something in the color setup that I was missing.

What I’ve been doing lately through an action:
- The 16-bit Adobe RGB file @ web size gets a color balance layer which adds a touch of Cyan
- A curve adds a touch of lightening
- Converts it to a sRGB 8-bit file
- Saves it as a jpg (not through save for web)

And that is very close to what I see on my monitor. Sometimes it is a bit off and sometimes not - depending I think on how much red was in the image to start with.

Obviously, I didn’t have this problem (uh challenge) when I was working with b&w, though even there you always have the issue of mac gamma being lighter than windows.

I’ve started exporting all of my images through Lightroom (someone may even have made an export to Wordpress) and no longer have this problem.

Exporting to sRGB through Lightroom gives me the same results, i.e. slight reddish shift.

Jeremy - are you on a a mac or pc?

Also, if you take a color image and put into Photoshop and proof it with MONITOR - do you see a color shift?
