Default Contrast problem

Hello,

I just finished submitting a photo that I very carefully adjusted (I shoot in raw). When I clicked on the link while awaiting review, I noticed the contrast of the submitted photo viewed through the site was substantially different (much more contrast) than the original jpeg, viewed side by side. Does anyone have any suggestions as to what causes this and how to prevent? Thanks,

Scott

I've had this problem since the first day I uploaded a shot to the web over a decade ago. I've tried various suggestions to fix this issue with no luck. I have come to terms with the fact that this is just the way it is (for me, at least).

The inverse happens when I download images from the web and open them in photoshop.

Scott,

Did you process the shot in sRGB or Adobe RGB?

Hey, how come your images look darker and much richer when I download them and open them in photoshop? Here is a screen shot of one of your shots I just grabbed. Can you see the color difference as I see it in photoshop? On the left is the pic online:

Interesting. Don't know, but maybe you should download all my shots so they look better!

The shots that I have processed in Photoshop appear to be the same when I open them in Photoshop or the image on the web. I do notice a difference though when I look at images that were opened prior to processing in photoshop or my web browser. I'm not quite sure why either...

I've noticed a significant change in the image as well. I have no idea what does it but regardless of which way I save the file once uploaded it changes.

Come on, I was waiting for your expert answer! Have I stumped you??

Really...I don't quite understand why this happens. I've asked countless people and with each suggestion they've given, nothing changes. Hence the reason why I've just accepted this as the way it is and nothing can be done about it.

Here is a screenshot of one of yours, John. The image on the left is as seen on the web, and on the right as seen in photoshop.

It's almost like PS uses it's own calibration for color and contrast which differs in comparison to the computer monitor or other programs used to view images.

In other words, I have no idea! Would be nice to know what's going on though!

I'd have to check my camera to see which, but I believe sRBG. I don't understand why the jpeg opened with Windows default photo viewer looks like the picture when I edit in Nikon CaptureNX2, but once I upload to railpictures and opene the picture in their site it looks so much different? I can upload the same picture to rrpicturearchives.net and it looks the same as in the photo viewer, so why does the picture look different in railpictures?

well, I think I just found something out. I just noticed the problem the other day (day of my post).... which was sometime shortly after allowing the firefox upgrade to 3.5. I went back and looked at my older pictures already on railpictures and realized the contrast was worse than I remember.... so I tried looking them up in internet explorer, and the contrast was the way I remembered... Strange!

All photo's get compressed on up load, That may have something to do with it?

Agreed, but Jim is only using a copy of the on-line image so, in theory!, they should look the same

Scott, the Firefox / IE comparison is interesting. I have recently switched to Firefox (IE8 is pants, or whetever the equivalent expression is over that side of the pond ), but can't say that I have noticed a difference; will have to make some comparisons when I get home.

Exactly. What I want to know is why images downloaded from the web look darker (and usually much more vivid) when I open them in PS, which is the inverse of what is happening upon uploading.
