A few people mentioned in the Aquatica/5D thread that they would like to see some samples from the 5D.

The attached image was from a series of images I created to see how the 5D would capture sunballs.

Aside from levels and a bit of color adjustment, there have been no changes to the image. No noise reduction was done to give you an idea of what ISO 100, pushed 3 full stops from RAW, looks like. (the smaller image is 100% crop).

The scientific result: ... cool :P .sunball.jpg

Looks good.

Can you take the ISO 100 shot and instead of pushing 3 stops, push less or not at all and use curves to bring out the dark parts.

Hello,

It looks like only 2 of the fou images you attached "made it" onto the post. Can you resubmit them?

Thanks in advance,

I used curves to bring up the shadows in these. EC=0

I see all four images above... from my viewpoint, they seem to all be there.

The first image (ISO 100) is very encouraging. There is nothing wrong with that sunburst in my eyes.

The second one less so, as the sunball is very large and not well controlled.

I'd be interested to see what the JPGs straight from the camera looked like too.

The 100% crops have a lot of noise/repeat banding in them. I guess this might be the high ISO you used (actually no, it is in the ISO 100 one as well)? Maybe they are JPG artifacts? Or maybe a problem associated with the failed uploading?

I would have expected to see worse images when pushing from ISO 640 to over ISO 5000 by software only, only ambient light and compressed as attachments. This looks very promising to me and confirms what I have experienced with the 5D topside so far. The dark foreground is not really important as it is not lightened by strobes. But still looking good for ambient light only and conditions stated above. Even the intentionally overexposed sunburst doesn’t suffer under too strong colour fringing around it.

Thanks for sharing.

As a whole, the sunball shots are getting much better that the days of two years ago. Probably a combo of technique, conditions and camera sensor quality.

The experiment was to see how well the rest of the picture would survive when exposing for the sunburst. In the end, grad ND filters will still result in the best images, but with a bit (and sometimes a lot) of color noise reduction, the images are not all that bad.
