sarav Posted August 21, 2014 Share #1 Posted August 21, 2014 Advertisement (gone after registration) In very low light condition with my M9 I set ISO 640 and -3 stop Exposure compensation, in LR I overexpose, little bit of Noise Reduction (very low, I don't like plastic digital photos), some contrast and I get a good picture. With M (Type-240) I tried to do the same with ISO 800 but I'm getting ver bad banding noise in dark areas (like skies or uniform surface areas) and I can't avoid it. Have any of you found a workaround? Thanks, Sara P.S. when shooting 3200 on camera I'm getting banding too. Link to post Share on other sites More sharing options...

furcafe Posted August 27, 2014 Share #2 Posted August 27, 2014 This is a well-known issue w/the M 240 in severely underexposed shots. A related, & unique to the M 240, problem is the very visible green tint in the shadows that comes from "push" processing, but a solution is discussed in this thread (there are also some links to articles that touch on the banding issue): http://www.l-camera-forum.com/leica-forum/digital-post-processing-forum/337638-correcting-green-shadows.html In very low light condition with my M9 I set ISO 640 and -3 stop Exposure compensation, in LR I overexpose, little bit of Noise Reduction (very low, I don't like plastic digital photos), some contrast and I get a good picture.

250swb Posted August 27, 2014 Share #3 Posted August 27, 2014 Banding is caused by underexposure, so given you are dialling in -3 stops exposure compensation you have a massive amount of underexposure. So you are doing your best, albeit with I suspect some reason behind it, to shoot yourself in the foot. That one camera does better under this torture could be a result of the fundamental difference in the sensor. There is no elixir, the laws of photography still apply, Lightroom is not your Saviour, light, and more of it, is. Steve Link to post Share on other sites More sharing options...
Echo63 Posted August 28, 2014 Share #4 Posted August 28, 2014 wind the ISO up to 6400 iso, and expose the image properly (keep the important hilights, but let ultra bright spots blow out) the noise isn't that bad. heres an example from a job i did a while ago #1 is the full image #2 and #3 are 100% crops showing the noise (NR of "15" applied in LR) this is a properly exposed image at 6400ISO illuminated only by candlelight Welcome, dear visitor!

Echo63 Posted August 28, 2014 Share #5 Posted August 28, 2014 and a colour example too, this one has "19" NR applied in LR i will export a few 6400 iso ones with No NR applied at all when i get a chance and post them up too. i find its better to shoot a little bright (without blowing out important highlights) and then darken the image in LR or PS, lightening the image seems to introduce the banding you are seeing Welcome, dear visitor!

sarav Posted August 30, 2014 Author Share #6 Posted August 30, 2014 Dear Echo63 I've never used 6400 ISO. I thought it was unusable. I was wrong, your shots demonstrate how deep you can go with that ISO setting. I'll experiment it in the coming days and I'll expose blowing ultra bright spots. Thank you very much. Now I'm going to read the thread suggested by furcafe, too. Sara Link to post Share on other sites More sharing options...
edwardkaraa Posted August 30, 2014 Share #7 Posted August 30, 2014 Advertisement (gone after registration) My M240 started showing severe banding only recently. Prior to that it was very minimal. The shots are not underexposed and not pushed in LR. I'm not sure if it's the new firmware because otherwise I haven't changed a single setting in the menu.

Sara Ok, heres a better example, original file is a RAW from the M240 #1 is a screen grab from PS, showing the selected area #2 is a closer look, (100% crop) with no NR applied (turned off completely in LR, it normally applies 25 colour by default (on my copy anyway) #3 is the settings i added #4 is the effect of those settings on the file above (no other difference between the frames, other than NR Welcome, dear visitor!

sarav Posted September 2, 2014 Author Share #10 Posted September 2, 2014 It looks similar to a good shot at 3200 ISO with some NR. As I said I've never used PUSH ISO because I've had bad results with other cameras and looking at your crops is a new revealing experience. Thank you again for your detailed post.
