Here are some examples that have ca, and fringing.

What do I need to do to get rid of it and what adjustments in my shooting do I need to use .

Really just getting started in earnest and need all the help I can get.

Thanks,
Dave

I don't really see any other than in the little girl picture, and it is hard to tell if it is CA or compression and sharpening.
Where do you see it? Around the little girl I see some, but it looks like sharpening halos, and might be sharpening color aberration in a blue tint against her skin vs light sky around her.
All of these pictures are over sharpened, noisy, overcompressed, and appear to be maybe iffy focus to boot.
I know you didn't post full quality, but if these aren't true of the original, you can't judge by these examples.
To avoid CA, use smaller apertures (not diffraction small, just F8 or so for most lenses), use quality lenses, avoid extremes of wide or zoom (if that lens is prone). Shoot RAW and use the CA correction in Adobe Camera RAW, or see if your camera has a JPEG correction for CA.
Good Luck.

bigdaver,

Thank you for your information. I,m trying to get my feet on the ground with this and probably am overly ambitious when it comes to editing.
I find it interesting that you say out of focus. When I looked at these on my computer at 100% I thought they were ok. I really want to work to develope an eye like yours and turn out really good material. I'm in the medical field and am looking toward retiring but would like to get good enough with photog.to develope a second income. Trying to talk wifey into moving to Belize ,lol ,and this would be very useful.

I'll conclude with much thanks and with a realization that I've got a lot to learn . Depending on knowledgable folks like you to help.

Thanks again,
Dave

I am looking at possibly getting a camera that is touted to be notorious for color fringing ON THE SIDES AND CORNERS. (Canon 5D Mark II)

New to this, I am wanting to know if correcting fringing (by any number of software programs available) will find this problematic as it shifts for the WHOLE image and not just the edges and corners. What say?

I don't see any CA either. If you want to see CA and flare here it is. Both often happens when shooting directly into the sun as it happened in this picture

Its not so much the camera as it is the lens. The lens is what directs all the colors of the spectrum onto the sensor. Cheaper lenses fall short of being able to converge all those colors correctly. So concentrate on good lenses.
