Bags Of Dust
Posted: Thu Sep 15, 2005 8:17 am
This post is prompted by Big Pix's link concerning camera bags and the response to yesterday's revelation that Canon have developed a new camera-body cap which does not attract dust.
My point is this: Isn't it time that camera luggage manufacturers addressed the issue of dust a little more fervently in their design and fabrication?
Part of the distinction between working with 35mm or 120/220 on the one hand and sheet film on the other is the increased risk and presence of dust. It gets into the film folders and it gets into the camera bellows and as a result it gets onto the imaging sirface of the film itself and results in clear bits on a negative or black bits on a transparency or print. A major factor in my sheet film workflow is dust control. Each time I use my film holders I vacuum them out with a strong vacuum cleaner with a computer and electronics cleaning nozzle attached (available $20 from Godfreys). I also vacuum out the case in which I carry the holders each time at least, if not more freqently. All the cases used for transporting film holders seal with a gasket and none have furry dust-catcher linings or partitions. On a regular basis I can even get stuck in with a damp cloth and wipe them out.
Similar situation with the camera: I vacuum out the insoide of the bellows and all the little recesses, nooks and crannies of the metal castings that support the bellows.
Although I did use a 'back-pack' as a camera bag for a while I very quickly gave the idea the flick. The tendency is to lie it down, fully open it and access your gear. Down near the ground in the big wide world is where all the crap is. On the calmest of days you will see surface vectors moving fine crap about. Add to this the fact that the unzipped cover is languishing about in the ground and only getting secondary attention at best it is hardly surprising to find that a lot of junk gets into the bag when the lid is flipped back over.
Now, where does the muck of the world go to once it is inside the bag? Into the cells of the foam rubber or into the nap of the velcro or felt that lines many bags and makes partitions. Like most things this accululation of detritus is stubborn when we try to get rid of it but quite promiscuous when we take our eyes off it and give it nice positively charged instruments that will just suck it onto itself in a trice.
I feel it in my waters that similar precautions are necessary equally necessary with a DSLR. But waht are camera bag makers doing about this? I feel that the linings of Kata bags are probablyresistant to imbedded dust and grit but how are they sealed for when we're trudging about in a filthy city or a dusty hinterland?
Despite all my anal precautionary action to prevent dust in my luggage it still gets in and I can count on finding a speck on a varying number of images per year. A particle of dust on a 4x5 negative is only linearly enlarged 4 times to make a 16x20 print. But a 4 times linear enlargement of even a 36x24 sensor's iamge will yield only a 6x4 inch print. Want something bigger and the specks are getting bigger.
Now of course I hear you say that dust-busting in PhotoShop will take care if it .... but only suprficially and not without the expenditure of time (and time is money) and some risk of deleterious artefacts. In effect, the time and effort I spend on dust control BEFORE the shoot is transferred, like so much in digital photography, to AFTER the shoot.
We will never be free of the dust peril but it would be nice to think that some of the makers of peripheral gear had our best interests at heart.
Cheers,
