kraig_cuddeford Posted May 28, 2005 Share Posted May 28, 2005 I got pictures of fireworks with my 20D for the first time. I'm wondering if there is something wrong with my camera. I see what looks like gaps in the exposure on the red channel, or over exposure on the red channel in a repeating pattern. I didn't see that with the fireworks pictures from a 10D Link to comment Share on other sites More sharing options...
kraig_cuddeford Posted May 28, 2005 Author Share Posted May 28, 2005 I also notice a bunch of cross hatching in the darker blue. Link to comment Share on other sites More sharing options...
kraig_cuddeford Posted May 28, 2005 Author Share Posted May 28, 2005 and some big chunky gradients in the blue background. Link to comment Share on other sites More sharing options...
kraig_cuddeford Posted May 28, 2005 Author Share Posted May 28, 2005 ahh, this picture is the one with the big ugly gradients, the next one shows the cross hatches.. Is there something wrong with digital photo professional's conversion settings? Link to comment Share on other sites More sharing options...
kraig_cuddeford Posted May 28, 2005 Author Share Posted May 28, 2005 I've converted the file from raw using several different settings to compare the results.. One is oversharpened with too low of an image quality setting, resulting in the large chunky jpg gradient in the blue tonal changes. The other is showing the cross hatch pattern that everyone else is complaining about, I can't remedy the cross hatching, if it's in the raw file due to exposure failure or other condition, it's there... Do you think Neat Image or Noise Ninja would be acceptable on a large print? Link to comment Share on other sites More sharing options...
darklights Posted May 28, 2005 Share Posted May 28, 2005 Honestly, on my screen it looks overexposed. As far as Noise ninja or neat image,I haven't gotten anything to look good with them past 8x10. Not sure about the cross hatching, someone else'll have to broach that one. Link to comment Share on other sites More sharing options...
dave_nelson___atlanta__ga Posted May 29, 2005 Share Posted May 29, 2005 Can you past a link to an original file? I have shot a lot of fireworks with both a 20D and 10D and have never seen these problems. The second photo looks very similar to JPEG artifacts.

kraig_cuddeford Posted May 29, 2005 Author Share Posted May 29, 2005 Do you have any originals that I can compare? I ran the 20D with ef-s 18-55 at like 30mm f11 and 3-6 seconds to get a little ambient exposure.. mlu and timer. I want to get a good setting to use before the 4th.

andy_depaulo Posted May 30, 2005 Share Posted May 30, 2005 Looks to me like some nasty JPG and sharpening artifacts, with a little blooming mixed in here and there, but mostly the former. Can you host a raw for us to play with? Link to comment Share on other sites More sharing options...
kraig_cuddeford Posted June 3, 2005 Author Share Posted June 3, 2005 not really, The raw file looks OK, there are some optical errors due to the lens cleaning and sensor dirt, but for the most part, I am concerned with the image processing. Any suggestions I can do on the raw file in DPP or should I be looking for another program? Link to comment Share on other sites More sharing options...
