pemayeux Posted February 22, 2007 Share #1 Â Posted February 22, 2007 Advertisement (gone after registration) We spent the weekend traveling old Rt 66 between Oklahoma City and Shamrock, TX. I've spent the last couple of nights converting the DNGs to TIFFs. The first attachment is the question. Is this the banding? I was shooting the 35/1.4 with the hood, The sun was over my shoulder. It's a firmware 1.09. It has not shown up in other shots. Glad I was nursing The Glenlevit. Link to post Share on other sites More sharing options...
bnelson Posted February 22, 2007 Share #2 Â Posted February 22, 2007 Paul... Where are the slots for the credit card on these pumps? Can you still buy gas with money? Â Just kidding. Great color but I'm unsure on this band. Maybe someone else has seen them. Â Bill Link to post Share on other sites More sharing options...
pemayeux Posted February 22, 2007 Author Share #3 Â Posted February 22, 2007 thanks Bill - most of the cars around here still use Ethyl too. Well on a more serious note, I've been scouring the search engine and haven't found anything like it. And I don't remember seeing it when it was first downloaded. Maybe it's the computer. I've already reformatted the SD card so I can't go back and check it. Paul. Link to post Share on other sites More sharing options...
adan Posted February 22, 2007 Share #4 Â Posted February 22, 2007 Assuming a horizontal shot before you cropped it: Â it doesn't look like the bright-light-source bands, because it doesn't extend all the way to the edge (the white wall and pump handles are clean). Also it is too intense and too thin to match those. Â It also doesn't look like the waterfall effect from shooting too soon after the camera is turned on/awakened - and that would be from the top down, rather than horizontal (thus the "waterfall" name). And there would be many more lines (fainter) Â I suspect a data burp on the SD card. It may be a one-time deal, or it may show up again if the card has a real problem. Â Just to check on "safe" computing factors: Â 1) You always FORMAT the SD card to empty it for a new shoot, and don't just use the "Delete All" command, right? Â 2) You format, delete, and otherwise make changes to the data on the SD card only in the camera, and never from your computer? Â 3) You never read files directly from the SD card, but always copy everything to the computer first and then work with those copies? Link to post Share on other sites More sharing options...
pemayeux Posted February 22, 2007 Author Share #5 Â Posted February 22, 2007 Yes I only clear the card by reformatting in the camera. I use a Sandisk card reader to transfer the information to the computer and the files are always read from the harddrive of the computer. I was hoping a card burp may be the culprit but I've never had it happen before. Thanks, Paul. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted February 22, 2007 Share #6 Â Posted February 22, 2007 Paul sometimes it can be the reader. Do you still have the images on the SD card and if so try to download from the camera instead . if not there than it is the reader if still there than SD card. Need to find which is the culprit Link to post Share on other sites More sharing options...
Jamie Roberts Posted February 22, 2007 Share #7 Â Posted February 22, 2007 Advertisement (gone after registration) Wow. Haven't seen this yet. I suspect Leica is still fine-tuning the readout timing of the sensor... I hope they nail this soon, though. Â On the other hand, this looks a bit like the post where the direct sun causes a rare 'sensor overload' streak; but I don't see any overwhelming light source in the frame...

pemayeux Posted February 22, 2007 Author Share #8 Â Posted February 22, 2007 Guy - unfortunately I reformatted the card after I downloaded to the computer. Prior to reformatting I went through all of the frames and I didn't see any problems. Also, there were about 90 shots after this and the streak never reappeared. This frame was about in the middle of the batch that was downloaded. It makes me wonder about the card reader as well. I'm using the Extreme III 2GB card fwiw. Â Jamie - The sun was high in the sky - and not coming in perpendicular to the camera. I've shot some where there was a strong (and only) light source coming in from the side and the file showed nothing unusual. Â The card reader so far sounds like the best theory. I've got more shots to download from yesterday, I'll use the same card reader and see what happens. Now that card prices are so low, I'm going to go pick up some extras. Â Thanks, Paul.

Guest guy_mancuso Posted February 22, 2007 Share #9  Posted February 22, 2007 Paul before you download the next card in the reader , download it on a seperate drive from the camera using the USB cable and rename the folder. Than try the card reader again. i think it is the card reader myself and there have been reports of this on a Mac or troubles on a Mac. If you can, I think you are in the states go to a Comp Usa store or a Best Buy and just get the type for SD card only USB or order one from here  I have this one and it works fine on the Mac pro Lexar Quatro Drive SD/MMC/MS/XD Reader  or this one works also  Sandisk MobileMate SD+ 5-in-1 Card Reader  I order Transcend cards from these guys all the time , These are cheap and work great also   Can't beleive the price on these. I have 4 already the price is so low  Transcend 4GB 150X Secure Digital Card Link to post Share on other sites More sharing options...
Jamie Roberts Posted February 22, 2007 Share #10 Â Posted February 22, 2007 Hey Paul-- Â I hope it's the card reader! Let us know if it is Link to post Share on other sites More sharing options...
pemayeux Posted February 22, 2007 Author Share #11 Â Posted February 22, 2007 Thanks Guy - I'll do that. I've been using the Sandisk 5 in 1 reader that connects to the USB. There's a Circuit City down the street, I'll run over there and pick up one that reads SD only. I'm going to order some of those 4GB Transcends. Can't believe the change in the prices, but I'm happy. Â Jamie - I'll update one way or the other. Thanks, Paul. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted February 22, 2007 Share #12 Â Posted February 22, 2007 Yea its 20 bucks to find out if it is but try to do some process of elimination just so you know exactly what the issue is. It sounds like a reader too me because it is not always there on all files so the camera sounds okay so they next things are cards and there readers. I think I remember this with Canons also and the DMR with readers which makes me suspect this. It's certainly worth the effort Link to post Share on other sites More sharing options...
wlaidlaw Posted February 22, 2007 Share #13 Â Posted February 22, 2007 The Macally reader/USB hub woorks fine on Macs too. It has occasionally been able to read and/or reformat a corrupt or dying card that refuses to read in a camera. Â Wilson Link to post Share on other sites More sharing options...
ho_co Posted February 23, 2007 Share #14 Â Posted February 23, 2007 Looks to me a lot like the problems shown in http://www.leica-camera-user.com/digital-forum/17131-m8-stripes-but-not-banding-problem.html?posted=1#post180420. Link to post Share on other sites More sharing options...
pemayeux Posted February 23, 2007 Author Share #15 Â Posted February 23, 2007 Well - I tested the camera as suggested and was not able to get the defect to reappear. So I tossed the old card reader and now have a new Sandisk Mobile SD card reader. I actually like it better than the other, it is much more compact. Here is a shot from that batch taken with the 75 'lux at f2 iso 160. No sharpening only a slight adjustment to the color temperature in C1. Link to post Share on other sites More sharing options...

pemayeux Posted February 23, 2007 Author Share #18 Â Posted February 23, 2007 Thanks Guy - I have a feeling the reader was on it's way out. I bought it when I purchased my D2 when they hit the market. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted February 23, 2007 Share #19 Â Posted February 23, 2007 This unfortunetaly is fairly common even with Canons, I have seen this several times. I think we forget that working in the electronic world there is just all kinds of interference or circuitry that can screw things up. It does scare the daylights out of you sometimes. I was thinking about starting a best practice thread for the M8. Just over the years i have seen some weird stuff that are most of the time avoidable, stuff is going to happen and no way to get around that just like dropping your film at a lab and comes back (if your lucky) scratched. Just a different technology now Link to post Share on other sites More sharing options...
