Finally got to do a gig with my k-x & DA*50-135mm

Well amazing I have to say, this gig was in a very very dark room with very little lighting.

ISO 6400
Aperture f/2.8
Shutter 1/60
Focal length 135mm

No cropping, chose this image at random so not necessary a test of photographic skill.

Original image with raw to jpeg conversion in Lightroom 2.7



Now quickly using noise ninja in Photoshop CS4 & then auto adjust colours & tones.

Simply amazing

Very nice....
I prefer the top version for the extra texture) but the lower one for the color. Looks like there's quite a bit of detail in the file though(nice work)

K10d at ISO 2500-3200

After changing my noise reduction and sharpening method I am now willing to use ISO 1600 on my K10D. Some of these pics are pushed 0.5 or 1EV in PP, so the effective ISO is perhaps 2500-3200.

I chose to keep the warm light in the color pics. The location was a pub with no stage lights.....just candle lights and a few lamps.














Kind regards

Just thought I would post a few taken on vacation recently, at a Aquarium in Gatlinburg. Light was really bad and I was shooting at iso 3200 just to get half way decent shutter speeds. Shot with the K7 and DA *16-50.

I was quite happy how this shot came out. These guys visit my frontyard all the time at the moment. It was a overcast morning so high ISO was the only option. Minimal PP - just a slight sharpen on resize.
K-x, 3200 ISO, old Sigma 100-300mm UC zoom.

K-7 iso 3200.

I know this isn't what people are mostly going for in this thread, but I like it. RAW conversion in-camera -- using the "blue filter" option of the in-camera RAW converter (not the "effects") which (particularly in this lighting) maximizes the visibility of noise; no NR (obviously), no other post-processing except minimal for resizing.

Did you use an PP NR?

Very clean shots, goes to show you that the K-7's high ISO isn't as bad as they make it.

Just curious how old is your K-7? did you get it when it came out or did you wait?

Sure, it's possible to do a little better with a different camera and more sophisticated NR techniques. But I remain satified with what the humble K200D can do with just a simple preset applied during RAW processing in ACDSee Pro. This one at "true" ISO 1600 (no push processing), minimal NR:



And this one at the push processed equivalent of ISO 4500:

I have been using a Nikon D5000 and I just aquired a K-7. I am pretty sure my K-7 can handle iso noise better than my Nikon. I use the strong noise reduction feature inside the camera. I have noticed iso noise gets stronger in low light. Also when I crop and sharpen photos I have noticed noise starts to appear. In good outdoor light, I have gone up to iso 800 with my K-7 with no noise after I am finished editing it.

I am impressed with the high iso photos in this thread. Some of you must be using computer software for eliminating it. I use Corel and it just takes what little there is away.

I reprocessed the master RAW files to zero noise reduction before I exported them. If I missed one they would have only minimal processing on them, as I don't use noise ninja or anything like that.

I got my K-7 just a couple weeks ago.

Fits with my theory and rumours that later version of the K7 have had minor hardware revisions.

Just for the hell of it...

I was bored, so I figured I'd see what I could squeeze out of a K20D ISO3200 snap. None other than a flawless full size image. (insert dancing banana here ).

Grocery list:
  • ACR6.2
  • CS5
  • Denoise 4.2
ETA: 7-10 minutes(thanks to topaz...)

It could have used debanding(see right OOF regions) but, since it wasn't serious, I figured it wasn't worth the effort

...the end

ISO 3200 shots in Vegas using DA 40mm Ltd

In retrospect, I had enough light at these Las Vegas night shots to go with 800 ISO and keep a reasonable shutter speed, and I probably should have.
