I have found that at times, photos that I upload to challenges are darker than shown in my editor (Elements 6), particularly mid-tones. I have my color profile set to sRGB. My camera is set to sRGB also. Sometimes I have to go back and re-edit my photo to brighten the mid-tones, so that after uploading, the photo on DPC is a closer match to my original edit as shown in my editor. Can anyone please tell me why?

I have no answer, just another question, as mine does the same thing except opposite. I find my colors are a little washed out(or lighter) when I veiw them on DPC compared to photoshop. Mabey one post will be able to answer both our questions.

Resizing and save for web robs local area contrast, and this is most noticeable in the midtones. The images I post up look too sharp and contrasty at full size. When you talk about "as shown in my editor" are you referring to the saved-for-web image viewed at 100%, or the fit-to-screen image before saving for web?

If you're not loading and viewing the saved-for-web version before posting it to the challenge, that may be where the difference is.

I resize my photos to the 800 pixel limit at 72ppi (I call this my low resolution version) before doing a "Save-for-Web". The "as shown in my editor" version is the final 800 pixel, 72 ppi viewed at print size, not fit-to-screen.

My latest upload problem was with a photo that ended up less than 300k for the low resolution file, so I did not have to us the "Save for Web" command. So my comparison was between identical files on DPC and in my editor. The DPC version was much darker in the mid-tones.

FWIW, 72 ppi is meaningless in this context, all that matters is the actual number of pixels. But that's neither here nor there...

Beyond that, I have no explanation for you. I expect to see a difference between the 800-pixel, photoshop image and the save-for-web image I make from that. My 800-pixel, layered PSD file is a little more contrasty and luminous than it appears when I have saved for web, as a rule, so I amp it up a little for that reason, mostly via Adamus sharpening. This would not seem to be your problem, however, based on what you are saying.
