Anyone interested in processing an HDR?

dchemist · 08-22-2017, 09:05 PM

I have 5 exposures (.PEF or .JPG) of this week's eclipse that I'd love to see processed as an HDR- but I don't have the software or processing power. Is anyone interested in processing it?

Post them and see what happens...:-)

I believe they are too large to upload... Let me know the best way to share them. Or message me your e-mail address and I'll send a link to the files on Google Drive.

Suggestion: To transfer directly you could use Google's "We transfer". No problem of size for 3-5 shots.
Sorry, I'd not process them...😞

Sure, sounds like a nifty challenge to me! You could share the PEFs on Dropbox, send them out via weTransfer or get them hosted on PF's challenges site.

Sorry Darren but there's not a lot I can do with these. The dynamic range is quite similar in all exposures and rather binary: either completely black or completely blown-out. Only the size of the corona varies from exposure to exposure. On top of that, there's quite a nasty bit of purple fringing going on (probably the Tamron 70-300 I have used in the past as well but unsure whether another lens at 300mm would have done better). You're better off just going with the middle exposure as-is.

Not a problem- thanks for taking a look, I appreciate that.

Send them to me. I'm willing to give them a try. Here's my totality composite.

Figures somebody from Corona could make a good HDR of the corona....

Looks great.

Thanks. This is composite of 26 shots ranging from 1/4000 to 1sec. Aligned and stacked manually in Photoshop.

Here's my attempt with Darren's images. Nice detail including Regulus (which I missed in my shots due to the camera orientation).

Focus was a bit soft and alignment was a bit problematic, but make of it what you will.
