Default What is this?

I have a canon G5 and do alot of landscape pics, I have found that in the sky I seem to get alot of sort of splotchy looking color. You can see it if you look in the lic below. On screen when you view the full pic it is not that visible but I recently had some 8x10's printed and it is much more visible in the prints. It is most noticeable around the cloud.


Please help.

I have PS CS so if there are any tricks to get rid of this I would really appreciate it.

Thank you
Don

I think that's just noise. I use Grain Surgery 2 in Photoshop.

www.neatimage.com is another solution.

Another is to not use as high an ISO setting. The higher the ISO, the more noise. (its one of the things you get in a more expensive camera, usually.... less noise at higher ISO's.)

I took this picture at ISO 50. This is why I originally did not think that it would be noise.

I just downloaded neat image if you have any tips please let me know.

Also there is no noise in the detailed sections of the image only in the sky.

Thanks for your help.

Default What resolution are you on?

I used a G5 and it came defaulted to fine. Moving it to the Extra Fine setting may help if you hadn't already tried it. Also try shooting in the RAW mode and see if that clears it up. Also try turning off the continous focus if you using it. I found that to cause a lot of issues that didn't occur in single focus.

Ah, jpg noise. Could be.

I agree with hst, continous focus is evil. Only use it when it directly makes sense to do so (like pictures of your kids running aorund the back yard.)

Take pictures at each ISO of a white piece of paper and use that to train neat image. Use those to build profiles and save them. Load the one that matches the ISO you used. I believe the neatimage web site talks about doing this.

I haven't done much with the many sliders. To be honest I don't understand them but I've been happy with the results with even the simple knowledge that I have.
