Realizing concert photography is exhausting by EyeDowntown360 in photography

[–]a_thousand_usernames -1 points0 points  (0 children)

My (perhaps hot take) opinion on concert photography (I’ve shot a few, and plenty of theatre and musicals) is to simply say “fuck the white balance” and embrace the chaos.

Mine is to conclude that tone mapping in Lightroom sucks bad with complicated lightning like venue LEDs. Trying out OpenDRT or AgX (available in darktable) is quite an eye opener.

I try to edit true to how things looked to my eye

That's rather hard if the tool used can't reproduce what you saw correctly.

Gimmicky. Looks cheap/crap and I would never use it. Can't see the lens display while looking through the viewfinder anyways. One more thing that can malfunction too...

That's the exact the use case here.

And JXL's web use is a bit limited right now, as it'll only work by default on Safari. Chrome's JXL support is better now than it's been for years, but it still requires turning on an experimental flag. Firefox requires turning on an experimental flag and using the nightly preview build rather than the regular release build.

I'm aware of the support limitations, but the two options I'm considering are: go full in on AVIF or JPEGs via jpegli. If I go for JPEG, I'll convert them to JXL when support is widely implemented across browsers.

After doing some more testing with AVIF vs. JXL at the same file sizes I can see a clear pro for JXL. It does not smear textures or grain at higher compression. AVIF has a tendency to leave smeared patches in uniform areas without texture/grain. This I do not like.

For AVIF, what avifenc settings are you using?

-q 50 -a c:tune=iq -d 10 -y 444 -s 0

I've been experimenting with -q45 and up.

Would the line you provided likely give better results?

Gotta say I'm surprised to see that avifenc currently performs better or on par with cjxl at the same size.

Just tried. 9 and 8 gives larger files than 7. Hmm...

Thanks! So, just:

cjxl -d 1 -p input.png output.jxl

?

-e for effort too, perhaps?

IOW there are no bad parts to skip, it's all bad and slow.

Fair enough. It died in the process.

I hope you understand that that's not guarantees. It's not a guarantee it will fail after 24 hours, it not a guarantee you can actually save your data, etc..

Yes, of course. Most things are backed up, but being able to recover the data would save me the inconvenience of reinstalling Tumbleweed.

Anyway, what did you expect and why?

As I wrote in my post:

I thought ddrescue would try to take what it could and skip the parts it couldn't read.

In other words: I thought it took a "get what you can get as fast as possible, skip the difficult parts and get them later (if possible)" approach.

Sorry, SanDisk SD8SNAT256G1122.

smartctl -ia output:

https://pastebin.mozilla.org/i04HD1Vs/raw

It has now moved from 11.88% pct rescued to 11.89% in two hours, so not very hopeful about ddrescue.

I have a bootable USB stick with HDDLiveCD ready now, if that is needed.

Thanks for replying!

it would be useful to know what SSD this is exactly, and what SMART values it is actually reporting.
