I love my 50D, but some days I wish I could put the 450D guts into the 50D body. With the same lenses, I keep running into issues I never saw with the 450D. Anyways, here's the problem at hand.The full picture below probably looks fine, but if you pixel-peep the hat has a lot of "fringing" for lack of better word. This is a converted RAW file. The second picture shows a 100% crop of the hat. I didn't think the fringing would show up on the print that bad, but wow, it did. The third picture is a 100% crop of the in camera JPG (I shoot RAW+JPG) it is there but NOWHERE near as pronounced.I was thinking this was some kind of CA, but using the CA sliders in Lightroom will not fix it. I try color saturations, and it (as you would expect) desaturates the picture too much. Any ideas ?Setup: 50D with 24-105L and UV Filter. Someone suggested filter being a problem, but that doesn't make sense with the difference in the in camera JPG and the RAW cropped picture.Full size picture100% crop from converted RAW100% crop from in camera JPG

did you try to process the image with DPP and the correction of Chromatic aberration that is included ?Because the jpeg looks much better

Same question as SEBOUNET. What software used to convert? I would expect DPP would probably be a "better fit" with the 50D's raw files than others.SEBOUNETwrote:did you try to process the image with DPP and the correction of Chromatic aberration that is included ?Because the jpeg looks much better

I actually used Lightroom to process and did try the CA corrections to no avail. Didn't think about DPP at the time since I hate the user interface.

Well, you nailed it. Can't believe I overlooked that. I really wish Canon would release the inner workings of their RAW format. I'd pay extra to not have to use DPP.

1/160th of a second. That may be a bit slow if the lens is close to 100mm. If the photographer does not have good technique, it may be too slow anyway.Anyway, it could be an artifact which DPP can fix. BTW There is a separate button in the program to do noise removal. It is not likely it will do it unless you push that button.greetings,

Not quite sure I understand what shutter speed has to do with it. Care to explain?

I don't think it's link to shutter speed, because all the other parts of the photo are sharp. To have this kind of ghosting with slow speed it could be obtain with flash use for example.Also i don't like DPP, but it's like adobe actually need to improve the raw treatment for 50D, because DPP seems to do a better job

I have to deal with that in most shots made with the EF-S 17-55mm.
