Loosing color after uploading - DPChallenge Forums

05/28/2006 04:59:57 PM · #1

I just got the new MacPro 17" laptop and now using PS7 for editing (all of which is new to me). I find my photos look great on the laptop, print just the way I see them but when I upload here they are loosing a lot of their color. I've uploaded to my own website without a problem. Any suggestions? Here is an example...

DPC upload

on my site...

tighten it then ... ;o)

All kidding aside, what colour space do you use to edit?

When uploaded, an image is in the sRGB colour space. This colour space is narrower than say Adobe RGB 1998 which is the most common space used for editing.

I am using the sRGB color space when editing :)

There goes that theory. :(

Both the DPC image and the one on your site look the same to me. Are you seeing them differently when opened in a browser side by side?

When uploading to the web, be sure to change the colorspace to sRGB, as it is the standard for web images.

DPC does not do any color management at all, so the images are not changed during the upload -- although I do believe I remember it being said that profiles were stripped from the image, but not certain of that.

I'm using Firefox to view the two websites and so I can quickly switch between views (tabs). And aside from the harsh white (almost hurts my eyes) background of your website, I don't see a difference between the images.

I'm using Safari to view .. could that be the problem? They look significantly different to me.

Edit to say .. the background on my website is suppose to be black .. thank you for pointing out the white .. I will fix that after dinner!!

I also use Firefox and the photos look the same to me. Maybe you should try using Firefox

I'm not seeing any difference in them in either Firefox or IE.

Yes Kat, it's not just you, they really do look totally different in Safari, but the same in Firefox (and in Flock)! The one on your site viewed in Safari is obviously the only one that's rendering correctly. The DPC one in Safari (and both seen in Firefox) have lost much of the green saturation and gained a muddled brown look.

I've been battling this exact same problem, but maybe the thread bvoi linked in here has the solution: the claim is View-->Proof Setup-->Monitor RGB has to be selected while you do all your Photoshop work. Then of course you need to convert for Adobe RGB to sRGB before saving for the Web, but I assume you know all about that. I'll try to verify this for myself tonight.

But one thing still baffles me: if Kat and I were doing this wrong, how come the images still looked fine when viewed in Safari and hosted somewhere else than DPC?

I have my camera to shoot in sRGB mode and also choose the same workspace in PS7, then save for web. Bvoi .. thanks for the link, it's worth a shot.

Magnus .. I have the same ? .. it's only on DPC that I am experiencing this problem.

Dragging both images into photoshop tells the tale.

If you didn't do it prior to uploading, then DPC does indeed strip embedded color profiles. The image from DPC does not have an embedded profile, while the one from your site has AdobeRGB as the embedded profile.

You will need to actually convert to the sRGB profile before saving. If, as you say, your editing is done in the sRGB color space, something is not right somewhere. Check the camera and PS -- somewhere it is picking up an AdobeRGB profile.

I can only guess that Safari is aware of embedded profiles (either natively or from a plugin), which is nice for you -- but the web in general does not recognize color profiles so it is best to not rely on them for web content.

I put the photo back in ps7 and made sure the color profile was set to sRGB and saved it again .. here is the new and it definately looks a lot better. Not exactly like I see elsewhere, but I can live with this.

hmmm... your DPC upload actually looks more vibrant and better on my screen to me than on your website (same colors though)... might just be me as well, and of course, I didn't get a chance to see your original DPC upload.

05/28/2006 08:44:34 PM · #16

LOL Sorry .. you don't want to .. it looked pretty bad :)

Kat,

I'm glad you got this fixed.

I'm using a Mac and Firefox is my standard browser. I've just brought up four copies of your baby robin: DPC/Safari, DPC/Firefox, 1bydesign/Safari, and 1bydesign/Firefox. My screen is big enough so that I can see all four of them at once. They all look essentially the same to me.

Amanda said that she thought the DPC upload was a little more vibrant. I think I can see what she means, but it is a fairly subtle effect. I think it is due to the difference in the backgrounds. You have a black background on 1bydesign and DPC provides a gray background.

Thanks for taking a look Dan :) I really didn't plan to put Firefox on here ... at least not yet. I'm still getting use to Mac, PS7 and loving the differences so far.

Just tried the same four as wheeledd and I see the 1bydesign/Safari with significantly more saturated green than the other three. But with what David.C surmised, this makes sense. Safari must be able to correctly interpret the Adobe RGB profile on the 1bydesign image. Which also explains why it looks exactly the same in Safari as when I drag it over to Photoshop. And DPC clearly strips all profiles out of files, hence the DPC image looks exactly the same in Safari and Firefox.

If I understand this correctly, while it's very important to have your monitor calibrated to sRGB and to do your editing in ProofColors-->MonitorRGB mode, it makes no difference what profile you convert to before uploading to DPC since it's going to be stripped away anyway (contrary to what all the tutorials say).

So, only if you are posting to some other site that doesn't strip the profile, and you know your audience uses Safari, then the final attached profile matters?
