eronald Posted November 4, 2006 Share #1 Posted November 4, 2006 Advertisement (gone after registration) My M8 makes lengthwise streaks in night photos at ISO 1250. Below that images look good. Is this usual or should I send images to Solms in view of asking for an exchange ? Edmund Link to post Share on other sites More sharing options...

robsteve Posted November 4, 2006 Share #2 Posted November 4, 2006 Edmund: Can you put up an image as an example. I tried running Pascal's small jpeg through Camerabit's Band Aide and it cleaned up quite easily. I need a high resolution or original DNG to experiment a little further. Band Aide wad developed when the Nikon D1 was introduced and it produced lots of banding at 800iso. The Canon 1D also had some banding at 800iso, but a firmware update cleaned most of it up.

eronald Posted November 4, 2006 Author Share #3 Posted November 4, 2006 Iv'e attached a DNG with some streaks to this post. My first impressions (no photo tests) are at Edmund Ronald's Test Blog Edmund L1000073.DNG Link to post Share on other sites More sharing options...
robsteve Posted November 4, 2006 Share #4 Posted November 4, 2006 I am downloading it now. I didn't realize you could attach files here. Can I process it and post it here? Link to post Share on other sites More sharing options...
innerimager Posted November 4, 2006 Share #5 Posted November 4, 2006 Edmund- That sure is a tremendous amount of magenta casting is it not? That strikes me more so than the banding......Peter Link to post Share on other sites More sharing options...

RobSteve - You're welcome to do whatever you want with this image ! If you push it a bit, you'll also note that the bottom right asphalt zone also seems to have a different shadow base-level. The annoying part is that the banding is clearly visible even in the unpushed image. Peter - I dunno about the casts - this image is not gray balanced.

robsteve Posted November 4, 2006 Share #7 Posted November 4, 2006 Advertisement (gone after registration) Edmund: I just opened it in Lightroom and the only banding I can see is off the headlights of the car, not the other shadow areas. I don't have bandaide loaded on my desktop and my laptop was choking on having all the programs open to deal with it. I have to go out and do some shopping, but will try it later.

pascal_meheut Posted November 4, 2006 Share #8 Posted November 4, 2006 The magenta cast can be removed by applying my custom profile. There is some streaking indeed but it is hardly noticeable. It is more obvious when the background is less dark. I'll do some other tests tonight or tomorrow and shot the pictures with both the M8 and the DMR. If I have a clear test case, I'll report it to Leica. 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!

robsteve Posted November 4, 2006 Share #9 Posted November 4, 2006 Just as another note, so people don't start panicking about high ISO, large cities like Paris can be shot at 400iso or less at night. Below are two pictures on E200 slide film using the Noctilux. One is Paris, the other London. Using a f1.4 lens, you could be shooting the M8 at 320. Welcome, dear visitor!

eronald Posted November 4, 2006 Author Share #10 Posted November 4, 2006 Robsteve, Hehe, your pictures are so much nicer than my picture ...must be the equipment I'll reshoot my images again too, to check, and if the problems persist I'll report it.

graham_mitchell Posted November 4, 2006 Share #11 Posted November 4, 2006 I couldn;t help noticing that the banding coincidences with very bright sources of light, i.e. the headlights. Almost like a lens flare effect. Interesting to see if others can replicate this. Link to post Share on other sites More sharing options...

Beautiful light... Im sure the M8 will provide some beautiful images, but so far I haven't seen anything that compares to the quality of those two shots. Of course I've only seen early test shots, and "the best is yet to come" Cheers, William Link to post Share on other sites More sharing options...
robsteve Posted November 4, 2006 Share #14 Posted November 4, 2006 Put a Noctilux on a M8 and shoot at 320iso and you will probably get better night shots. The digital will have more range than slide film. Link to post Share on other sites More sharing options...

Chromes are great for good color when you're dead on exposure but not otherwise. -g Link to post Share on other sites More sharing options...

Below are two pictures on E200 slide film using the Noctilux. One is Paris, the other London. Using a f1.4 lens, you could be shooting the M8 at 320. Rob, the problem with that statement is that currently there are no 35 f1.4 equivalent lens for the M8 - even with my 28 cron, I can approximate a 28, but I certainly can't get f1.4! This problem is worrrying - for the money on the M8 and for Leica's exacting high standards, it is not acceptable if it's indeed a problem on all production cameras. Originally I thought it was only on Pascal's camera, as he was the first to get it It's true the Nikon D1 and the original Canon 1D had some banding issues when they were first released, but they were released more than 3 years ago, at a time when digital technology was not as mature as it is now. I think the reason why Sean might not have detected this problem in his review is that a large percentage of his shots are day time shots or shots with no strong light sources. Sean, if u're reading this, do u have any comments on the banding issue? Would there a an article on it soon? This is cause for a little longer wait before buying a M8. I live in Asia where it is not so convenient to be sending a camera back to Germany and waiting for it to be repaired, esp since I need it for work!

Hi Reddawn, Actually, I mentioned light banding at ISO 2500 in my review (Part Two) but it was a rare occurence. It can be seen in the ISO 2500 example picture of the kid flipping burgers.The reason I almost never saw it is that I generally do not place lighting sources themselves within the frame. In this picture, there was a bare bulb (with a wire surround) that appeared in the frame. I want to speak with Leica on Monday to get certain information and then I'll write about this. In all the examples I've seen posted here on the forum so far, the light streaks correspond with a light source in the frame which is many times brighter than the rest of the subject.

Cheers, Sean Wow Sean that was a quick reply Thanks for all the hard work and the help and feedback you have given to Leica. U're as much a part of the developmemt of the M8 as the folks at Solms! I just checked out part 2 of ur review. Hmm, I can't see any banding in the picture you mentioned - maybe because it's been converted to black and white... also I'm pleasantly surprised you added a section on moire. Perhaps you can consider putting a notice on the front page of the site with a list of updated articles by date so that readers like me who read it earlier will not miss the new additions to the article itself? Check out this example in the other thread which could be of use in helping Leica find the problem: http://www.leica-camera-user.com/digital-forum/8672-banding-some-more-tests.html#post84569 This looks like an ordinary picture for me in an orginally hall. Notice the streaking from the left side of the image. Actually, it's so obvious anyone would have spotted it without being prompted to look..... I hope these are all possible to fix with just firmware. Link to post Share on other sites More sharing options...

I hope these are all possible to fix with just firmware. Hi David, Thanks, but I really have played a large part in the development of the M8. You can see the streaks at the same "lattitude" as the light bulb near the right edge of the frame. They certainly don't jump out at one. Good idea about the article update list. Within the articles themselves, the updates has dates listed where they begin. Cheers, Sean Link to post Share on other sites More sharing options...
