kidigital Posted January 7, 2007 Share #1  Posted January 7, 2007 Advertisement (gone after registration) After keeping my M8 dialed to ISO 640 or lower on most shots, I've begun to experiment with the camera at higher ISO levels. With proper exposure, I must say that ISO 1250 on the M8 is better than some give it credit for being. As others have mentioned, the key is making certain that shots at higher ISO levels aren't underexposed.  Here is a shot with the 75lux at f1.7 and ISO 1250. Welcome, dear visitor!

mike prevette Posted January 7, 2007 Share #2 Â Posted January 7, 2007 This has been my experience as well A properly exposed image at 1250 looks great. But It's a slippery slope into noiseville if you fub the exposure. I've actually been very surprised when reviewing my shots how different they can look shot to shot at the same ISO.

Stevez4 Posted January 7, 2007 Share #3 Â Posted January 7, 2007 Shots at 1250 from my recent shoot in Sicily are all over the map. It is amazing to see several of the same scene all at the same exposure. Its auto baracketing of a sort..I hope that this will be included in the major fix that Sean is talking about in another thread. Link to post Share on other sites More sharing options...
khanosu Posted January 7, 2007 Share #4  Posted January 7, 2007 Hi Kurt, your picture shows good high iso performance with excellent colors.  Here is a 100% screen capture crop of a portion of a 1250 iso picture that has been scaled so that it appears 8in by 12in on my monitor. In other words this is how a portion of an 8in by 12in print of this picture should roughly appear to the eye. M8 keeps the noise well controlled in the midtones and highlights at 1250 iso. The scene is well lit by natural light but I still needed this high iso to keep the shutter speed at a reasonable 1/60 sec. to avoid excessive motion blur as my daughter was moving around energetically. The 50mm Summicron was fully open to keep the 1/60 sec shutter speed.  Furrukh Welcome, dear visitor!

gtmerideth Posted January 8, 2007 Share #5 Â Posted January 8, 2007 that's what I like about this forum. always something new to try. great work and high iso, gentlemen! g. Link to post Share on other sites More sharing options...
neila Posted January 8, 2007 Share #6 Â Posted January 8, 2007 Kurt, your photo is great - and I love the subject (particularly as I have a 9 year old daughter who does nothing but stare into her Nintendo in a similar pose!). Â Furrukh, that's a great shot for 1250 - I'm not getting those sorts of results, although I have the same lens. I need to try harder! Link to post Share on other sites More sharing options...
xrogers Posted January 8, 2007 Share #7 Â Posted January 8, 2007 Advertisement (gone after registration) My experience mirrors yours. If you underexpose even a bit, the noise leaps out, but with enough light the results are quite usable, and can show great detail. And for black and white, I think the results at 2500 are often underrated, and are quite usable. Â I have never seen Steve's wandering exposure phenomenon on consecutive shots, and I commonly shoot three in a row when shooting handheld static subjects at low shutter speed (so I can later choose one with the least motion blur). Sometimes in this situation, however, the automatic white balance loses its mind, and changes markedly between two of the exposures. This can make the exposure seem quite different, even though later manual white balance of the DNGs shows the exposures to all be the same. Could that be what's happening?

khanosu Posted January 8, 2007 Share #8  Posted January 8, 2007 Thanks Everyone! If you have reasonably good light (and my example shows that there are conditions when you might need high iso even in good light) and the scene is dominated by high mid-tones and high-tones and low-tones then 1250 iso color pictures look good printed at 8in by 12in with good tonal variations and detail – the colors come out really beautiful without being washed out. As others have stated the exposure has to be good and the histogram nudged to the right (bright) side. Also remember that tungsten lighting will exaggerate the noise once you color balance it which amplifies the noisy blue channel.  Furrukh Link to post Share on other sites More sharing options...
wparsonsgisnet Posted January 8, 2007 Share #9  Posted January 8, 2007 In another thread, I have posted iso 2500 photos:  http://www.leica-camera-user.com/digital-forum/13096-more-fun-than.html  These clearly show some noise, tho they have been thru Neat Image. These pix are the result of my first attempt to use Jamie's chrome profile. I think I can improve them with tweaking some settings and also by more work in the Neat Image software.  However, the noise doesn't bother me.  Not to steal his thunder, Sean Reid has done extensive tests of the M8 against a full-frame Canon and he says that although the Canon produces lower noise images the Leica lenses make up for it. Canon, of course, wins the noise battle because the pixel is larger  Based on my experience of electronics in audio applications, I would expect that it is difficult to make the response of the sensor linear over a wide range. Therefore, in the future, maybe we'll see an M8-low and an M8-high, where the sensor in the body has been designed to capture low-iso images or high-iso images.

osera Posted January 8, 2007 Share #16 Â Posted January 8, 2007 Kurt, your photo is great - and I love the subject (particularly as I have a 9 year old daughter who does nothing but stare into her Nintendo in a similar pose!). Â Hey, that's the same pose that my 9 year old daughter strikes during much of her free time! Maybe they could get together and all stare into their Nintendo's together... Â Â Actually, I'm not all that bothered by "noise." I usually add noise/grain to my favorite images. Whether the noise from the M8 at 1250 is better than noise/grain added in post or better than grain from scanned film is "better," I personally think that it is a matter of personal preference. It also matters to my eye if I'm looking at an on-screen image or a print. I see images where the noise is reduced with post processing, the resolution is well-preserved, but I think the overall image is diminished. That's just me.

jaapv Posted January 9, 2007 Share #17 Â Posted January 9, 2007 Let me try: 75/1.4, wide open, tungsten/candles, ISO 1250, 1/16th, hand-held. No Neat Image. I think noise is not an issue here, this kind of thing is what the M8 is made for. Now if only somebody came up with a solution for motion blur in those conditions....(Other than Superglue that is ) Link to post Share on other sites More sharing options...
carstenw Posted January 9, 2007 Share #18 Â Posted January 9, 2007 Sorry to be a pain, but on both my 5D and my M8 I see more noise at these ISOs than these images show. I also expose to the right. We need to see crops with no noise treatments, not rescales, and here the 5D clearly jumps ahead, in my experience. I still prefer the M8, I am just saying...

Eoin Posted January 9, 2007 Share #19  Posted January 9, 2007 Here is one I took inside a dark church, tungsten lit from above shot @ ISO2500 Summilux 35 asph with IR/Cut filter just run through c1 to process to sRGB web size. I think it looks very clean. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!
