First Attempt at merging/processing Eclipse picture
Mar 8, 2018 15:52:24 #
My wife and I traveled to Wyoming to watch/photograph the total eclipse last August. When I shot the eclipse, I shot a series of pictures during totality with only the shutter speed changing. As you shoot slower and slower shutter speeds, the corona can be seen further out from the surface of the sun. Unfortunately, the parts of the corona closer to the sun then become too bright (over exposed). Since everyone and his brother posted Eclipse pictures back in August, I refrained from adding mine since they looked so much like all the others. However, I finally got around to doing a composite merging of several photos in Photoshop that blends all 9 or 10 photos and normalizes the exposure across the entire corona so the entire corona looks properly exposed. It involves a bunch of Photoshop magic. I did not get all the images lined up as well as I would have liked, but I'll try this process again taking more care later. Overall I was pretty happy with the result for my first attempt at this kind of processing. Equipment uses was a Canon 7D Mark II with a Sigma 150-600mm lens on a tripod with a Gimbal head.
This is based on 9 or 10 images, all shot at ISO100 f8, but with shutter speeds ranging from 1/1000th to 1 Sec. Zoom was locked at 500mm.

Basil: someone messaged me that there are people who want to send praisebfornthis and you set up the posting to ignore them. I don't want to get into a problem, just to let you know that there may be many more praises out there.

I'm afraid I'm not sure what you mean? I just posted it like a normal post - is there some setting or something I'm not aware of? Thanks in advance.

I really have no idea. Some one wrote saying that you somehow set up to ignore. Check your profile.

Ok, I understand.

Very good. In addition to the corona and disc, you got some prominences. I think some enlargement of higher magnification would show these better. Still, you did much better than I. I got mostly clouded out from Beatrice, Nebraska.

I was worried we might have been clouded over because, when we camped out on the ranch, we had rain overnight. Luckily, the day of the eclipse was cloud-free.
