craig_sander Posted June 25, 2007 Share Posted June 25, 2007 The little blower brush I have is just OK and I was wondering if the canned air had adverse affects on film. Link to comment Share on other sites More sharing options...
michaelging Posted June 25, 2007 Share Posted June 25, 2007 Only if you do not keep the can right side up, it sprays liquid if you do not. Link to comment Share on other sites More sharing options...
Michael R Freeman Posted June 25, 2007 Share Posted June 25, 2007 I would suggest that you get a "Rocket Blower" or similar large blower bulb for blowing dust from slides and negatives. If you mess up with the canned air (and you will, eventually) you'll get propellant all over the slide/neg and then you're screwed.

mendel_leisk Posted June 25, 2007 Share Posted June 25, 2007 I stick to manual blower for film, just to be on the safe side. Neither method will get everything. Canned air likely gets a bit more, but I just don't want to risk it. I have a can, but try to minimize it's use. And for something major things like dusting out the computer's inside, I find using a vacuum cleaner set to blow is much more effective. Also, helps the environment to reduce your use of these.

elliot_n Posted June 25, 2007 Share Posted June 25, 2007 Canned air works better at removing dust than any rubber blower bulb. Link to comment Share on other sites More sharing options...
john_h.1 Posted June 25, 2007 Share Posted June 25, 2007 "Canned air works better at removing dust than any rubber blower bulb." It sure does. Then all you have to worry about is how to remove the residual spray chemicals off the film when the those pesky accidents occur? Oh right, you can't.

spanky Posted June 26, 2007 Share Posted June 26, 2007 I also use one of those large hurricane blower bulbs after a teacher told me canned air can damage negs. So far so good... Link to comment Share on other sites More sharing options...
Ed_Ingold Posted June 26, 2007 Share Posted June 26, 2007 In canned "air" the air IS the propellant - a low-boiling liquid related to Freon. If the can is tipped too far, you may discharge liquid propellant which may contain non-volatile contaminents which leave spots. These droplets are extremely cold, -40 deg C or so, which may damage delicate surfaces like digital sensors. You will not have a problem if you keep the can upright and at least 6 inches from the film. Canned air is very dry, which tends to create static on the film (and other surfaces). However the velocity is high enough that it is effective in removing dust. It is expensive, so I use a conductive brush whenever possible, which is most of the time. You could get an oil-free airbrush compressor for about $50 - the price of about 10 cans of "air". Link to comment Share on other sites More sharing options...
plasma181 Posted June 26, 2007 Share Posted June 26, 2007 I use the canned propellent. I did have an accident when I was testing it out on low value negatives. But I have been careful and haven't had a problem since. Link to comment Share on other sites More sharing options...
hjoseph7 Posted June 27, 2007 Share Posted June 27, 2007 I found that a Soft cloth the kind you use to clean lenses and glass work better than Canned air and rocket blowers ! Link to comment Share on other sites More sharing options...
Ed_Ingold Posted June 27, 2007 Share Posted June 27, 2007 Harry, What do you use to remove the lint left by the cloth? Link to comment Share on other sites More sharing options...
hjoseph7 Posted June 27, 2007 Share Posted June 27, 2007 "What do you use to remove the lint left by the cloth?" These cloths are made of silk or special material and are lint free. I got mine free from the Nikon School of Photography when I enrolled in one of their classes. Link to comment Share on other sites More sharing options...

doc_w Posted June 27, 2007 Share Posted June 27, 2007 Just for the record: if you screw up and get propellant all over a b&w negative, just wash and dry it. It will likely be fine. I have done it. Having said that, it is a good idea not to get propellant all over the negative, just in case the odd time washing it does not work. Link to comment Share on other sites More sharing options...
