bob_carpenter1 Posted April 16, 2004 Share Posted April 16, 2004 I know this same scenario was posted from an earlier poster but I just discovered the same problem. We just got our 10D about a month ago with 1gig of Sandisk Ram. My wife took the camera to the zoo with my kids only to find that about 7 to 10 pictures where totally black. Today while shooting in the house on rapid mode. She shot about 7 pictures consecutively to find that about 2 of the pictures where black. Absolutely nothing there. Any idea what might be going on here? She is using the 550EZ flash with a 17-40 wideangle lens. However the same problem happened with a 28-80 lens. Both times she had the flash mounted Link to comment Share on other sites More sharing options...
peter_burns1 Posted April 16, 2004 Share Posted April 16, 2004 Not being funny, but did she take the lens cap off? Mind you, you wouldn't see anything with it on. The other possibility is that it was taking photo's with the lens cap on, by accidentaly triggering or knocking the shoot button, but auto focus wouldn't work allowing a photo I guess. Seems strange they are totally black, but what does the data in the photo show? That could be the key to an answer! Link to comment Share on other sites More sharing options...
Spearhead Posted April 16, 2004 Share Posted April 16, 2004 In burst mode, the flash won't charge fast enough unless you have an external power pack. It seems possible that on shots without flash, the exposure settigs could cause blank frames. Music and Portraits Blog: Life in Portugal Link to comment Share on other sites More sharing options...
bob_carpenter1 Posted April 16, 2004 Author Share Posted April 16, 2004 I'll forget the lens cap response. As far as the flash not charging fast enough, I dont believe thats the problem either. There is absolutely no picture, when viewing the picture after through the camera it is totally blank. If the flash didnt charge at least there would be something although dark. She wasnt shooting in total darkness. Link to comment Share on other sites More sharing options...
diego_garcia1 Posted April 16, 2004 Share Posted April 16, 2004 After i read your post i found this at www.dpreview.com on 10D review, conclusion, cons. "Opening the CF compartment door shuts camera down, loses any buffered images" maybe that is helpful, good luck!! Link to comment Share on other sites More sharing options...
bob_carpenter1 Posted April 17, 2004 Author Share Posted April 17, 2004 Nope, thats not helpful since she never opened the cf door in the first place. You notice the blank images immediately scanning through them via the camera lcd. We were playing around with it this evening and have noticed it a couple of times on rapid shot. Great camera though. Extremely happy with after having it for a month now. The new wideangle lens is fast and takes great pictures. I was a bit dissapointed with the cheaper 50mm lens that we got. We had some focusing issues. Since we've been using the wideangle ($700.00 lens) its been a pleasure. Link to comment Share on other sites More sharing options...
pascal_scheffers Posted April 17, 2004 Share Posted April 17, 2004 Are the file sizes the same for all those black images, and within the expected range for your shooting mode (raw, jpeg/quality/etc)? If they are in range and all slightly different, it suggests the camera is writing something to disk, which got corrupted somehow. If they are all the same size, which is very unlikely for real images, then something funny is going on. It could be media error, which you can check using the windows filesystem check (right click on the disk, properties, then tools). Which is no definitive test, but you have to start somewhere. Can you reproduce the problem with using another card? Link to comment Share on other sites More sharing options...
pascal_scheffers Posted April 17, 2004 Share Posted April 17, 2004 I see you wrote about your Mac in another thread, so disregard that windows advice... Apple will have something similar, somewhere. But you also write your images came out fragmented?!? That really sounds like corrupt media/format to me. Try to format the card in the camera (again, maybe) and do test with another card. If the card reader is to blame, it may have caused filesystem corruptions. Link to comment Share on other sites More sharing options...
rick_helmke Posted April 17, 2004 Share Posted April 17, 2004 If she was shooting inside the house then the flash may well have not re-charged in time if she shot 7 in a row quickly. Seeing absolutely nothing doesn't mean a lost image. Shooting inside at a small f/stop could yield a completely blank or black image. This has happened to me before in this situation. Check the file size of the blank image. I bet she just got ahead of the flash. Rick H. Link to comment Share on other sites More sharing options...
alexdi Posted April 18, 2004 Share Posted April 18, 2004 Run a black frame by autolevels in Photoshop (or anything else). If it stays black, I'd question the card. If not, check the exposure. Coincidentally, pull up the EXIF data and see if anything's amiss compared to the normal pictures. DI Link to comment Share on other sites More sharing options...
