Here is a short clip of fireworks in Canberra. Taken hand-held with the S9 + Sigma 45mm, MP4 lite format.

Do you have any de-noise tools? If you'd like, link me one of those totality raw's and I can try running it through the one I use.

I don't use anything, generally. There's a BlurXterminator plug-in in PixInsight I use for deep-space astro shots, but in general I try keeping the ISO setting low to prevent noise from being generated in the first place - it's a relic from my film days, I guess.

Dunno if this will work, but there's an RW2 file here:

Last weekend I had a short studio shoot with a very nice young lady. She is 21, what is not believable in some of the pictures...

Well, nuts. It looked like noise that On1 was able to do a pretty good job with on my pics, but this was the best I could get from it:

• 100-400mm F5-6.3 DG DN OS | Contemporary 020
• 373.0 mm
• ƒ/6.30000019073
• 1/8 sec
• Pattern
• ISO 6400

I think the ISO 6400 may have been part of it; I got the best results with shutter speed settings that kept the ISO between 800 and 1600.

A few more from playing around with different develop settings, and at different stages of the eclipse:

Liked the glow I got here. Almost SFnal.

I'm sure the high ISO number contributed, given how clear the pre-totality ISO 100 shots look, but on the other hand the Read Noise in the S5's sensor is pretty low at anything above ISO 600 or so, ...


This was taken from the Photons to Photos website's archive.
Also, between the shutter speeds I was using and the ambient temperature ("Brisk" would be an apt description), I don't believe my problem was thermal noise. I doubt the sensor had any time to heat up, even shooting at 1/5th of a second.

[*shrug*] I'm still pretty chuffed with what I got, all things considered. And I've got 5-6 years to think about how I'd do the next one differently. Your shots are impressive, so much so that I just swooped a mint-ish Tamron 55BB and a K&F Concept L-mount adaptor for myself off eBay last night. It could be the best $150 astro lens I've ever seen.
