c._h._h. Posted December 30, 2002 Share Posted December 30, 2002 Hi! Recently while performing the flashlight test on my camera, (that is while in a dark room, shining a flashlight into the mirror box with no lens attached and the mirror locked up), I noticed that there is a SLIGHT amount of light getting through the blades of the shutter curtain when I look at the curtain from an angle or from the bottom of the body. I need to know if this will affect my shots even the slightest bit. Thanks for your help! Link to comment Share on other sites More sharing options...
oliver_s. Posted December 30, 2002 Share Posted December 30, 2002 The film is unlikely to be behind the shutter at a large angle, and no SLR shutter is 100 per cent light-tight anyway as it spends 99.9 per cent of its life behind the mirror, which blocks most of the light. Unless your camera is very old (you're not telling us what model it is) and shows visible wear and tear of the shutter assembly (e.g. the notorious oily gum problem of the 6xx series), you're extremely unlikely to have a problem.<p>The easiest way to check is to shoot a few frames. (E.g. point the camera towards a brightly lit scene for several seconds--by no means directly to the sun if you value your eyes and the exposure metering system! Put the lens cap on and take a photograph with the shortest shutter speed and the lens fully stopped down. Repeat the procedure for a few frames. Check the developed negatives (or slides; not prints!) for dark areas.) Link to comment Share on other sites More sharing options...

cjtower Posted December 30, 2002 Share Posted December 30, 2002 ...I need to know if this will affect my shots even the slightest bit. Why? Why do you need to know this? To say the least it is unusual for this to matter so much to someone when it is nearly the year 2003, when professional photographers made it decade after decade after decade without giving it much if any concern at all. Five months later, and you are still obsessed with this? Isn't this the third or fourth time you have posted the same pointless question in the archived part of the EOS forum? Why not do the ovious thing and test the camera with film? If you cannot then tell if it affects the shots, well, guess what, it doesn't - least not enough to matter.

That's what's wrong with the world today, there are too many negative weak minded people like you out there! That go out of there way to insult and put down someone. Think about that my friend" Or maybe we've just grown tired of you repeatedly ignoring the advice people have tried to give you, and are trying to get you to stop pestering us?

miles stoddard Posted December 30, 2002 Share Posted December 30, 2002 If for some reason you want to see less light where you are looking, turn the flashlight off; if for some reason you want to see more light there, stick the tip of the flashlight right through the "curtain" till it comes out the back side of the camera! Since apparently you don't shoot film with your camera (if you did with slide film, you would know the answer to your question is irrelvant) neither one of these options would do much harm to your "photographic activities". Of course, you could call the Canon service line and explain your problem to them. Link to comment Share on other sites More sharing options...
carina Posted January 2, 2003 Share Posted January 2, 2003 If you need to know if this will affect your shots, the answer lies in your shots; all you need do is shoot slide film and examine it closely; it doesn't matter what you see with or without a flashlight, since what matter is what you see on the chromes.
