NDTPHOTOGRAPHY Posted July 31, 2018 Share #1 Posted July 31, 2018 Advertisement (gone after registration) For some odd reason, I decided not to bring my SL on my vacation to Budapest even though I knew full well I was going to take long exposures. I decided to take only my M10, using Lee Filters and a WATE. I took a couple of 4 minute exposures at ISO 100 and got horrible banding in the shadows as well as green dots in the highlights. Has anyone here experienced this? Does anyone here have any tips on long exposure settings (besides “use the SL” Link to post Share on other sites More sharing options...

250swb Posted July 31, 2018 Share #2 Posted July 31, 2018 It sounds like you underexposed the picture given the description. You are also using 100 ISO which is really an emergency extra stop for using fast lenses on the M10, it has a narrower dynamic range than using 200 ISO which is the better option. 1 Link to post Share on other sites More sharing options...

I also have tried 200ISO and for the same results. Have used the same setting on my SL in the past with anywhere from 4 to 7 minute exposures but had no banding whatsoever. Any other thoughts? Will upload a sample as soon as am able. Link to post Share on other sites More sharing options...
jaapv Posted July 31, 2018 Share #5 Posted July 31, 2018 I agree with Stephen that the most likely cause for banding is extreme underexposure. Coming from earlier M cameras, I didn't know that the M10 even did such long exposures. 1 Link to post Share on other sites More sharing options...

NDTPHOTOGRAPHY Posted July 31, 2018 Author Share #7 Posted July 31, 2018 (edited) Advertisement (gone after registration) Thanks all but still no answer. I have the most recent firmware and are exposed properly and just getting severe banding at ISO 100 - 200 with a 4 minute exposure. Does anyone out there have any suggestion as to a fix? I should have brought my SL but was trying to travel light, guess I’m paying for it in the end, trying to force a square peg... Thank you in advance for any insight.

a.noctilux Posted July 31, 2018 Share #8 Posted July 31, 2018 In your place, I'd avoid this 4 min. But maybe, I don't have customers for what I produce. 1 Link to post Share on other sites More sharing options...

Shoot most of work with it and never get banding. Link to post Share on other sites More sharing options...

I think you’re right, hence my “square peg” reference. I love my M10 but it’s jst not suited for long exposure.

a.noctilux Posted July 31, 2018 Share #11 Posted July 31, 2018 (edited) "Perfectly workable" = maybe NOt the best setting for every case In your place, I'd try other ISO (200, 400, 320 ?), just to experiment if it's better or NOT. I use M10 since early 2017, and the others ISO (200, 400, 320 ) are the "best rendering in my experience" in most case.

a.noctilux Posted July 31, 2018 Share #13 Posted July 31, 2018 That is severe banding. I've seen this kind of banding by M10 when I "tried" 25 K ISO or 50 K ISO. If in other ISO that happens, I'd go talking with nearest Leica Store where you are. 1 Link to post Share on other sites More sharing options...

frame-it Posted July 31, 2018 Share #15 Posted July 31, 2018 instead of avoiding 4 min exposures..send the camera to Leica to check so they can fix it In your place, I'd avoid this 4 min.

Shoot most of work with it and never get banding. No, 100 ISO is not the base ISO for the best dynamic range, 100 is simply the lowest ISO. How are you metering the shot, the M10's meter isn't sensitive enough to meter for 4 minutes so you must be doing it by trial and error or another calculation. I still think the image looks underexposed. So the point is if you aren't using the best ISO for dynamic range (200) you may be seeing clipping, which in turn leads you to underexpose.

jaapv Posted July 31, 2018 Share #18 Posted July 31, 2018 Sample file That is not normal underexposure banding. If you are sure that you were not near a strong RF source, send the file to Leica for evaluation. No, 100 ISO is not the base ISO for the best dynamic range, 100 is simply the lowest ISO. @ ISO 100 pull Even if ISO 100 is theoretically a pull setting, a chart of the usable photographic dynamic range - I call it exposure latitude to avoid confusion with the technical DR as measured by for instance DXO- will show us that in actual photography the DR at ISO 100 is still higher than at ISO 200. This can be attributed to two factors: 1. The actual base ISO of the sensor is somewhere between ISO 100 and 200, and the falloff from base-->100 is obviously less than the falloff from base -->200 2. The theoretical DR does not take the rolloff at the shoulders of the curve into account. Welcome, dear visitor!

Thanks for your reply, exposure is a bit subjective but I appreciate your perspective. This was shot at ISO 200, I think the base vs pull debate rages on... in any case thank you for your time and input. Link to post Share on other sites More sharing options...
