I was wondering - is it possible to convert a regular backpack into a workable & safe camera bag? I would really like to have a backpack type camera bag. I posted awhile back that I wanted a bag with zippers as opposed to those hard to open [for me anyway] plastic clip fasteners. I'm on a very tight budget at the moment so spending even $50 on a camera bag when I already have a nice one, albeit its being a pain in the a** for me to open now, is out of the question. I have a nice light weight backpack that I bought a few years ago when I drove to Maryland for a day at a large farm fair there and I did stick my minolta maxxum camera in the bag, stuffing it down into a soft rain jacket I had taken along. But it was just the camera and lens nothing else. I have some ideas for padding, but not sure they would work. I googled it last evening and only found one site with rather tedious and cheapy methods\directions using corrugated cardboard and bubble wrap to make a sleeve for the camera and that was about it. I have an old camera bag stored in the garage, and I thought perhaps I could use it's padding to somehow line the backpack? My other thought was cloth covered styrafoam I have lots of it on hand [we have a parrot and he likes to shred it - keeps him quiet ] But I'm wondering if that would be a bit too stiff. If anyone has any ideas I'd greatly appreciate them. Thanks.
