atufte Posted November 9, 2007 Author Share #21 Posted November 9, 2007 Advertisement (gone after registration) It's nice that your pictures look better after installing the new firmware, but I am pretty sure that this is just a result of comparing a successful shot after with an less successful shot before, each taken under different conditions. And without adequate documentation to compare things. I'm skeptical to start with because Leica doesn't seem to have touched this part of their code -- the WATE focal length selection dialog is unchanged, and there is still little communication between the ON and ON+UV/IR modes of in camera post processing. If you want to contribute to getting the M8 firmware to really do the best possible job of correcting for the tricky parts of wide angle imaging, please give all the relevant information. I don't see, for example, from your notes -- are you shooting in RAW (and if so, how did you develop, what color balance corrections, if any, did you apply, and what other settings were used to make the JPG) or did you shoot JPG, and if so with what in camera settings? -- what lens detection setting did you use? Sean Reid has a good methodology for shooting white walls and comparing center and corner colors. He uses 3500K lights and balances them on a white card to get reproduceable lighting, then click balances in C1 3.7.7 (so far, maybe he will switch to the 4.0 beta soon) and then compares the rgb levels found at the exact center of his "white wall" to the values seen at the corner of the frame. I just finished doing that with my dining room wall in indirect daylight, and will shoot again tonight in incandescent. I used a CV21/4 (uncoded) and found no difference between the result with lens detection OFF and with it ON, as expected. Then I shot with a CV15/4.5 coded with a JLM-mount to be a WATE, and told the camera that this WATE is set at 16mm focal length. I'l post the rest of the results tonight. scott I wrote in a earlier post in this thread that this files was converted by default setting in ACR , no color/wb tweaking what so ever... so there you go RAW/ACR and Lens detetction setting OFF...(and standard medium jpg compression after conversion, as if this matters:-) Link to post Share on other sites More sharing options...

charlesphoto99 Posted November 9, 2007 Share #22 Posted November 9, 2007 Hmmm, methinks there's a lot of wishful thinking going on re this new firewire update, such as the earlier thread that it produced better high iso results, and somebody else thinking their shutter sounded different. Such is the power of the human mind to fool one's self. But of course, I haven't had a chance to try the new fw update because my camera is still at the Solms M8 spa. And of course, the facilities are so nice (and the help so very slow) that it always seems to extend it's stay. Anyway, I'm looking forward to possibly picking up the 18mm, though really ready to jettison the M8 altogether for a camera that works consistently and I don't have to worry about coding adaptors, cyan corners etc etc. Link to post Share on other sites More sharing options...
wparsonsgisnet Posted November 9, 2007 Share #23 Posted November 9, 2007 Am I correct that fluorescent light is missing lots of the red spectrum? That could account for the lack of cyan corners in the first two shots, yes? BTW, the shutter sound different to me since the upgrade to 1.11. There seems to be a pause after the actuation and before the cocking motion. Link to post Share on other sites More sharing options...
carstenw Posted November 9, 2007 Share #24 Posted November 9, 2007 Could it be that Leica changed the settings for the WATE? I seem to recall someone complaining that the WATE was not properly corrected. This would of course not change lenses which are not coded. It would be possible that the camera now scans, for example, the top row of pixels, and specifically looks for cyan casts in the corners, correctly for it automatically. I think I will try my WATE without turning on lens recognition, and see what happens. I do have the old firmware, so I could do some comparison testing on the weekend.

TEBnewyork Posted November 10, 2007 Share #25 Posted November 10, 2007 Well, I've been busy the last couple of days and haven't updated the firmware yet. If someone would like me to take take a few shots of the same subject in the same light before and after the firmware, I'd be happy to do so. I don't have all my lenses coded for the moment but on the wide side you can chose from any of these cv's 15, 21, 28, 35. Just tell me how you want it set up. filter on lens detection set to ? etc. Terry Link to post Share on other sites More sharing options...

They can't even write a solution for the AWB let alone this. I still think it's just a case of wishful thinking. Link to post Share on other sites More sharing options...
bradhusick Posted November 10, 2007 Share #28 Posted November 10, 2007 As for image noise, I have shot side by side comparisons of firmware 1.10 and 1.11 at ISO 1250 and 2500 and I can tell no difference whatsoever in the images. Those hoping for improved noise handling (and who among us does not?) should not expect changes in this area. Leica made no claims here, so don't be surprised or disappointed. I, for one, am disappointed that they did not include SDHC card support in this release. Link to post Share on other sites More sharing options...
carstenw Posted November 10, 2007 Share #29 Posted November 10, 2007 How would it tell a cast from a sky? Well, it would look for differences between the middle and the corner, using a significant cyan cast in the corner region as an indicator that it should compensate. I don't know why they would do something like that, except that I don't see what would explain Alexander's result. Link to post Share on other sites More sharing options...
