Experiments in exposure bracketing. 5 images.

Not sure.  Seeing some artifacts that I assume are processing related.  Processed raw files in DPP4 into TIF’s. Then did the HDR composite in Affinity and exported as a JPEG. From Sanibel Island, FL a few days ago.

To be quite honest I don't really see it in the first image, nor am I sure it would have made much difference there. The more detail in the foreground, the more sense it makes to focus stack.

These aren’t focus stacks (for depth of field).  They are exposure brackets for HDR composites.

I rather like them since they don't have that artificial, fake look.  It would be interesting to see a non-hdr best exposure.

My own experience with HDR is that I could do just as well shooting RAW and then woirking the shadows and highlights a bit, but that may be because I was just using LR - not pushing things too much.

Sorry, that reveals more about my present obsession with focus stacking than about your image.

There is distracting concentric color banding around the sun on the 2nd image that is perhaps an artifact of the combined images and/or lens.  The green bands on the beach sand just don't work.

Noticed as well. Anything special in the compositing that would help or reduce that?  I’ll try to post a couple of the source images later.

Using Affinity Photo if anyone knows anything special there that might help.

I don't merge images so can't help with that.

However I have taken images like the 2nd and if I underexpose several stops (perhaps -3 EC) I can get a more defined image of the sun than this image has and can lift the shadows in post (with associated noise).  You should have some shots in the series that have a very defined sun, like the first image and some with well exposed foreground.

I think you're doing well. The first one has some aberrations in the sun itself around the inner circle at the edge, which could be easily removed. The 2nd one is tough due to the subject and controlling the flare inherent in that type of shot it's going to cause banding issues.

A normally processed single image. I suspect the dynamic range simply wasn’t enough to warrant that level of processing.

In the other image, the banding is evident in all of them.

Here’s a single shot at f/20 for points.
