Without seeinfg the full size image, the areas circled seem to resemble pixel clumping which are a symptom of over saturation.

Yes! Thank you!

I looked into that a while back and decided to use sRBG across the board, for compatibility with web and printing. I wish I didn't delete the images from my card!

Does that mean you indeed own a monitor that is not wide gamut? What model is it?

If you are indeed having problems its not with Canon. It's with sRGB. It's VERY easy to exceed. Shoot in aRGB if you want to maintain red detail.

I believe it's a 72% color gamut, its the HP Envy 17 notebook, bought it last year after my computer crashed and burned. So I should change my colour space to aRGB then, I'll give it a try.

Well the problem is that your monitor can't show aRGB. So even though the detail will be retained, you won't be able to see it. If you aren't color managing you'll see a lower saturation version of the image.

Welcome to the limits of sRGB. Share your frustration with me, I hate it too.

C'mon world...lets move to aRGB!

I was shooting in ProPhoto RGB but discovered that most places that print use sRGB, and the colours were off. Or they just convert to sRGB before they print your stuff.

Which is why some people print using their own printers. You can do a bit better than sRGB is certain areas. But yes, printers also don't tend to work well in sRGB. You're best bet is to shoot RAW and pull back image details into sRGB. I hate doing it but its the way things work right now.

why can't my monitor show aRGB? It's an option...

Because, as you said, your monitor doesn't cover the aRGB gamut. Which is why I asked if you had an adobeRGB monitor. The software can support it, the monitor can't display it.

Oh. That really sucks.

As I said, its not all that bad. You can shoot RAW and then pull back saturation and exposure, contrast etc. until you don't see this problem anymore. That's when you are in sRGB. Since you have a sRGB problem you should be able to visibly observe the problem as it disappears.

The picture doesn't look that bad to me. But I agree this is a color space problem.

Wide gamut RGB color space covers about 78% of visible colour, and sRBG 35% .... doesn't that make my monitor, which I believe is 72% wide enough....or is that a dumb question....

Guess it depends on what percentages we're talking about. Most monitors are rated to converage of a certain color space...not visible colors. I believe a 72% coverage of aRGB is typical amongst sRGB monitors. My monitor is 96% of aRGB. Very few laptops cover any significant portion of aRGB.

If you want to test it and have color management set up, load a aRGB image in internet explorer and photoshop. If they look identical, you have around a aRGB monitor. If the photoshop one looks more saturated, then you have a sRGB monitor.

Oh, guess I should have considered that when buying a new computer.:o The guy said my model was great for photography...doh! When I get a chance I will do as you suggest. Thanks for the input.

I think I understand some of what is being said, but the only time I had a problem like this my camera raw defaults had been somehow overwritten with junk.
