If I understand this thread it's about taking photos of guns in the event of theft, fire, and etc.
Being that as it may professional studio quality isn't neccessary to show the gun, the gun model, serial numbers, colors, stock types, optics, and etc. The photos need only be clear enough to serve the purpose they serve.
I ensure I take a 'front' and 'reverse' of the gun making sure I get a clear shot of the firearm make and model.
I also get a close-up of the serial number (multiple on some of the older mil surp rifles), close-ups of any optics markings, any particular marks that might later confirm identification such as a ding on a stock in a particular area, and etc.
I use a first model Sony Mavica that uses the floppy disc for memory storage.
I'm not advocating the particular camera but just saying that the camera does what I intend it to do when taking personal property photos.
My thoughts are that the photos are primarily used for proof of ownership to the insurance company and to assist law enforcment in the making of his report since they also enter info on all stolen firearms into various state and federal research data bases. But, in reality as soon as the Officer get's done with his report the photos he takes, if he even takes any, are soon forgotten about.
I keep the main disk copies in a safe deposit box and I keep a working copy here at the house. Each main disk is broken down into categories, i. e., handguns on one, rifles on another, shotguns on yet another and accessories on another. I also keep any purchase paperwork such as receipts, warranties, and etc. in the safe deposit box. I can't emphasize the importance of keeping copies of your purchase paperwork.....it proves purchase much more than mere photos that (in the mind of others) might actually be of "Uncle Bo's" or dads.
My working copies are like that also and when I have enough changes or additions to justify a trip to the bank I do so and replace the particular disk and bring the old one home for up-dating and that one then becomes my working copy.
I make plain paper copies of the photos and I place them in the three ring binders also broken down by category firearm types.
All of the gun material in the binders have directions on how to field strip them and some other such things as the bolts for cleaning purposes. I learn that since every gun has at least one particular trait that is frustrating and I tend to forget things I put the instructions in there for reference if I need them.
I also have histories on the guns but I did that just for the fun of it and since, particularly, the mil surp gun histories often intrigue me.
I had one burglary involving my guns and only got one back but not from the use of photos. But....the photos (and particularly the purchase paperwork copies) shut up my insurance company who, at first, questioned if I was pading my claim or that even the firearm ever existed.
I would also like to add that I make sure all of the firearm photos are taken in such a way as to identfy that the photo was taken in my home. That, to some, proves it was in the house so, likely, I owned it.
Having a good digital camera is a good investment but I'm not sure if everyone would want to buy one just for the occassional photo of a firearm that a good throw-away camera can provide.
Just my thoughts.
