ben_nauber Posted April 11, 2012 Share Posted April 11, 2012 <p>So, I've noticed what my untrained eye suspects is a light leak. See the included photos. Is this a light leak? Also, how would I go about fixing it?<br> <img src="http://i44.tinypic.com/120p8qo.jpg" alt="" width="1000" height="817" /><br> <img src="http://i43.tinypic.com/29fbbdd.jpg" alt="" width="827" height="1000" /><br /><br /></p> Link to comment Share on other sites More sharing options...
chris_waller Posted April 11, 2012 Share Posted April 11, 2012 <p>I am inclined to agree that it is a light leak. I suggest you examine the light seals around the film back and between the film back and the rotating mount. I had a similar problem and it was fixed by having the seals replaced.</p> Link to comment Share on other sites More sharing options...
russ_britt3 Posted April 11, 2012 Share Posted April 11, 2012 <p>Yes its a light leak, you can run a simple test by shooting in sunlight with black tape over the dark slide slot and see it its gone.</p> Link to comment Share on other sites More sharing options...
nathan_bonsal Posted April 11, 2012 Share Posted April 11, 2012 <p>In the near term, you can temporarily fix it by putting some black tape around the film back and over the dark slide slot, and slitting the dark slide slot with a razor. It'll be a heck of an inconvenience until you send it in, though. </p> Link to comment Share on other sites More sharing options...
marc_batters Posted April 11, 2012 Share Posted April 11, 2012 <p>Two good examples showing possible bellows, light leak.</p> <p>First image shows a [narrow band] from a more distant camera position - bellows retracted/compressed.<br /> Second image shows a [wide band] from a close-up shot - bellows extended, stretched further out.</p> <p>Might not be the back at all. Check the bellows for leaks.<br /> Do some test shots with a black T-shirt wrapped around the bellows.</p> <p>Do you have a Polaroid back and some Fuji pack film? This could easily confirm where the leak is coming from.</p> <p>My two cents.</p> Link to comment Share on other sites More sharing options...
paul ron Posted April 12, 2012 Share Posted April 12, 2012 <p>Take off the lens, fire the body so teh mirror is up, extend the bellows all the way out. Now put a bright light inside, chcek for light coming out in a dark room.<br> . </p> The more you say, the less people listen. Link to comment Share on other sites More sharing options...
wogears Posted April 13, 2012 Share Posted April 13, 2012 <p>You can buy a seal kit on eBay for about USD 10. It is easy to replace the existing seals, and cheap enough that you can buy two kits in case you mess up with the first.</p> Link to comment Share on other sites More sharing options...
john_c16 Posted April 19, 2012 Share Posted April 19, 2012 <p>Not a bellows leak. I've had the exact same one before - it's the darkslide slot seal. Very easy to replace felt seal. You may as well replace the rest of the foam seals, too.</p> Link to comment Share on other sites More sharing options...
tom_tao Posted May 2, 2012 Share Posted May 2, 2012 <p>Does anyone know where I can get foam light seal kit? I tried eBay already :(</p> Link to comment Share on other sites More sharing options...
rodrigo_carrasco Posted May 24, 2012 Share Posted May 24, 2012 <p>I got a complete light seal kit for my RB67 (body, revolving adapter, and 2 backs) from Jon Goodman a couple of months ago. Just google "Jon Goodman light seal kit" and you'll get his info. He is extremely nice and helpful. Installing the new light seals took me less than 30 minutes and I haven't seen any problems in my photos.</p> Link to comment Share on other sites More sharing options...
