Gone a bit green

As someone who's still learning, I'm trying to make sense of the following:

(1) I made a wallpaper in Photoshop Elements and saved one copy as a JPEG file, and another copy as a PNG file.

(2) I tried them both on my desktop. The JPEG was a trifle darker, but had the same pleasant green as the Photoshop file. The PNG was slightly paler, and the green had become a rather nasty olive.

(3) I viewed the offending PNG file in Photoshop Elements along with the JPEG - and now both of them had the pleasant green!

I assume the culprit is not the PNG format so much as the computer's wallpaper display - or then again, it did show the JPEG with the nicer shade of green, so it's obviously detecting some difference between the two. Maybe by the time the Caedes site has turned the PNG back into a JPEG, the colour will have calmed down again to the nicer green. Whereas if I send my JPEG instead, maybe the Caedes processing will darken it down again, which wouldn't be so good.

Well, that's how the wallpaper (not yet uploaded to Caedes) looks on my computer just now, but probably it would look completely different again on everybody else's computers, ranging from palest mint to darkest forest green.

Aieeeeee....

I *think* it also helps if you don't shoot w/ an adobe rgb.

like my camera has color modes of: IIIa, Ia, and Adobe something...i tend to stay away from the last one as the colors get messed up for web use.

(i don't think this is related to your jpg vs png issue though). *looks at time. Oh look, i gotta go to school* Sorry; I ran out of time. I'll be back later today - most likely without an answer.

what Noah is trying to say .. Adobe RGB

Losing Color on Uploads

Colour Matching

sRGB vs Adobe RGB

On-site JPG compression of red

In Photoshop (and possibly Elements) .. at the bottom of your "edit" menu is "color settings" .. make sure your RGB choice is sRGB ..

Thank you- the Losing Color on Uploads thread was particularly useful.

That does seem to solve the problem - I had to use a different profile, with the sRGB profile box checked when saving the file. The JPEG had been automatically saved with an RGB profile which explains why those colours stayed good.

I still don't understand why it looked different as a wallpaper when it was on the same monitor I created it on, but I suppose there's a reason for that. It's as well for me that there WAS a visible difference, as it made me do something about it. :-).

PNG allows for native gamma correction, so a PNG image will look just a little different on a Mac than on a PC. Also, Windows uses Internet Explorer to display images on the desktop, and the browser has notoriosly terrible PNG support.

Windows uses IE to display images .. IF .. the person doesn't have a competent image viewer

like .. (*wait for it*) .. irfanview, or faststone image viewer

It's an iMac I'm working on - bright and clear, but definitely gives different results from the PC. I checked the iMac calibration as far as I could a while ago; the PC wouldn't let me change some of its settings for some reason I never got to the bottom of. Never had time to look into it more. Anyway - thanks for the help! I'm getting some much nicer looking PNGs now. On my own computer, that is. :-).

I do all work in sRGB from camera through CS2. I would like to use the Adobe used in Lightroom but can't match it in the camera. My PNG's color match the JPEG's perfectly but the PNG gets the nod because it adds more detail. Tiff's are excellent but not accepted on Caedes.

(in the above links)

According to BRPHOTO .. a professional sports picture taker .. er, photographer .. adobe RGB 1998 contains MORE color data .. he shoots in it and edits RAW data in it .. then, finally, converts to sRGB for upload

and .. THAT .. is good enough for me .. now, sumbuddy give me a kamra that is all fancy like

He even has a few tutorials in his gallery

*wonders why it is my job to explain color modes*

However, the answer to why it looked different as a wallpaper on the same monitor is fairly simple. When you have the image open in PE, it reads the color mode/profile and displays it in that mode/profile for you (or asks you what profile you would like to use). Your computer's OS can't read the color profile embedded in the image, and so applies whatever you have set as the default profile for your monitor to the image, thereby altering a color here and there.

sRGB is the smallest color space (gamut range) that is universally accepted, so the colors w/in this small color space will almost always fall w/in everyone's usage, thereby preserving the intended colors no matter where they're going. Unless of course... your monitor needs some SERIOUS calibration. 8•P)

Ah - so that's Cat? Hello Cat. :-).

Thanks for the explanation - now I understand... I think. I was struggling with the fact that if you have the computer set to a specific display profile, that it doesn't necessarily display every single colour pixel in that light. I was forgetting the fact that computers' left hands quite often don't know what their right hands are doing.

One day in the far-flung future, computers will be more logical, like humans are...
