mdma Posted June 15, 2010 Share Posted June 15, 2010 <p>I recently purchased a yellow filter for my bw film photography, specifically a vintage toshiba one [for its retro charm ;)]<br> However, it is not perfectly clear and transparent; there are what appears to be grain or speckles as part of the glass (its not just dirt/dust), spread fairly consistently over the whole filter.<br> Will this affect the image quality in any discernible way? - ie. did I buy a dud?<br> I've attached a photo to better illustrate the issue.</p><div></div> Link to comment Share on other sites More sharing options...
lachaine Posted June 15, 2010 Share Posted June 15, 2010 <p>I would say that filter has outlived its usefulness.</p> Link to comment Share on other sites More sharing options...

JDMvW Posted June 15, 2010 Share Posted June 15, 2010 <p>Look at it this way, you have got a yellow <strong><em>diffusion</em></strong> filter for no extra cost. You don't even need to buy a jar of petroleum jelly.</p> Link to comment Share on other sites More sharing options...
mdma Posted June 15, 2010 Author Share Posted June 15, 2010 <p>I guess every cloud has a silver lining. Or at least a grainy one. </p> Link to comment Share on other sites More sharing options...
lachaine Posted June 15, 2010 Share Posted June 15, 2010 <p>I've used filters like that for toy camera photography on old vintage cameras, seriously. Picture perfect isn't exactly the goal with those, though. What you see as speckles is probably some layer separation.</p> Link to comment Share on other sites More sharing options...
sumo_kun Posted June 15, 2010 Share Posted June 15, 2010 <p>Are you sure its not dirt? It might be dried on oil. Get some alcohol and try wiping it. I've got many old Toshiba, Minolta Pentax etc filters and they are all clear.</p> Link to comment Share on other sites More sharing options...
mdma Posted June 16, 2010 Author Share Posted June 16, 2010 <p>Well when I feel it, only one side feels rough - the outer one. Unfortunately I have no rubbing alcohol at the moment so i tried a little 45% bourbon, to no avail however. Although it now smells amazing.<br> Ive taken a shot with it (the filter, not the bourbon) and ill put it up as soon as i get it processed.<br> Regardless of how it comes out, Ive got my sights on a beautiful silver Nikon Y48, which hopefully shouldn't have the same issue...</p> Link to comment Share on other sites More sharing options...
