P25 ISO 800

[John_Black]

I'm still kicking the tires on the P25 and trying to figure what's what.  When people talk about their P25, A22, CF22, etc., it's usually "ISO 50 and 100 are great, 200 is so-so and I never really shoot above that."  So, I didn't expect much out the P25 when came anything above ISO 100.  200 is noisier than expected, 400 can be used in a pinch with a good dose of noise reduction, but ISO is the big surprise.  The P25 (like the P45) bins the pixels, so the file is about 6 MP.  Well, my 6 MP 10D could never pull this off at ISO 800 -



This picture was just for fun as I was walking to the car earlier tonight - handheld too --- gasp...!...  It was shot +1 and then pulled back a stop in C1.  Yes, levels, colors and saturation were pushed however I wanted --- but that was the cool part --- the file could actually edited quite heavily without falling apart.  I'm sure the color accuracy on a portrait would be a mess at ISO 800, but at least it can do it.

Well, the problem isn't really the noise which is quite modest, but color blotches in the shadows (which you can see in the lower part of the doors) and it's even more evident when shooting people. This is not a problem when shooting B/W though, which is mostly what I use ISO800 on my P25 for.

Is this a P25 plus or "classic"?

That file looks amazing!!!

My P25 always looked like CRAP at 800.

MAy have to revisit it.

Is this processed with the new C1-4

Thanks,

Ric

This is the P25 Classic, not the Plus.  At ISO 800 the P25 bins the pixels, the resulting is image 25% of 22 MP (about a 5.5 MP image).  This one worked because the background tones matched the noise color.  If it were portrait with skin tones, that might be scary.  Processed with C1 Pro 3.7.7 and the noise control was almost max'd out.  I don't have any plans to leave the P25 permanently set at ISO 800, I was just surprised that it turned out at all.
