Advertisement Posted March 31, 2010 Posted March 31, 2010 Hi jaapv, Take a look here Trying out 2500 and Ecolight. I'm sure you'll find what you were looking for!
wparsonsgisnet Posted March 31, 2010 Share #2 Posted March 31, 2010 Jaap, in the first image it looks like the right-hand arm is more in focus. Are we seeing the left one for a particular reason? Or is the the back wall we are supposed to see? Link to post Share on other sites More sharing options...
barcoder Posted March 31, 2010 Share #3 Posted March 31, 2010 I assume Jaap is testing noise at ISO 2500 with a room lit with an Eco Light bulb in the lamp. Regardless the image has little (if any) noise. It's about as clean as you can get. Nice test shot! Link to post Share on other sites More sharing options...

Regardless the image has little (if any) noise. It's about as clean as you can get. Nice test shot! Well said I found the secret of high ISO shooting is to take care that the histogram is full. If you shoot so only the left side is used, the noise increases exponentially. The NR settings in C1- 5 were: Luminance 45 Color 64 Long exp 0 Sharpening: Sharpening 258 Radius 0.2 Threshold 0.7 Link to post Share on other sites More sharing options...
adan Posted March 31, 2010 Share #7 Posted March 31, 2010 Advertisement (gone after registration) I found the secret of high ISO shooting is to take care that the histogram is full. If you shoot so only the left side is used, the noise increases exponentially. Probably because if only the left side is filled, one is actually shooting at ISO 5000 (or higher). I agree!

jaapv Posted March 31, 2010 Author Share #8 Posted March 31, 2010 Jaap, in the first image it looks like the right-hand arm is more in focus. Are we seeing the left one for a particular reason? Or is the the back wall we are supposed to see? I'll happily provide a crop of the armrest I focussed on. However, I find it easier to judge noise in OOF areas.(Sorry there is a slight color difference. I redid the image for this crop and was too lazy to colormatch exactly) Link to post Share on other sites More sharing options...
jaapv Posted March 31, 2010 Author Share #9 Posted March 31, 2010 Probably because if only the left side is filled, one is actually shooting at ISO 5000 (or higher). I agree!That explains, of course why the Leica digitals have a reputation of being very noisy. If a DSLR is used in such circumstances, matrix-metering will bump the exposure up. If one forgets to expose the Leica correctly, in comes the noise... If the exposures are properly equalized, the difference is far less marked.

Nitnaros Posted March 31, 2010 Share #10 Posted March 31, 2010 I see a lot of "smearing", meaning the camera applies noise reduction post-mortem in firmware. Peter Link to post Share on other sites More sharing options...

Jerry_R Posted March 31, 2010 Share #12 Posted March 31, 2010 I must say, I am still in shock with LR3 results. I also made few 2500 checks. In fact you can remove color noise maximally, but keep luminance even untouched. After exporting to JPG with lower than oryginal resolution - if frame is not underexposed - it is perfect for me. The grain is pleasant, not disturbing like from LR2.6. For amateur pictures, not paid job - I don't need anything more. PS: I still will be using flash from time to time, as I like to play with effects it can give, not only use it for decreasing ISO. I also am not fan of paper DOF. So usable 2500 is best news since I bought M9. Now - only red corners remained ;-) Link to post Share on other sites More sharing options...
Shade Posted April 1, 2010 Share #13 Posted April 1, 2010 Here's my take on my ISO 2500. 100% crop. Processed with Adobe CS5, noise reduction using NIK Define 2.0 - 75% luminance and 75% noise, unsharp mask 300%, ratio 0.2, threshold 1. I think it's pretty good here.
