Not really, just because it is a cropped sensor doesn't mean it will act as a longer focal length in shaking respects. The shake would be just the same on a FF camera..

For the same size of final image, you have to enlarge the digital image one and a half times more than the film image. That increases the camera shake by the same amount.

I wasn't expecting, or even hoping to win this one, with that little snap. It's not a good photograph, I'm not claiming that it is. But if you intended your comment to be as disparaging of the ideas as it sounds, it's a little disappointing that there's so little room in composition for the offbeat. My apologies if I've misinterpreted you.
Yes, Chris, you have misinterpreted me. My laconic style can sometimes lead to that. Here's a smiley. George Lazarette wrote:

Strangely, I won a Mars bar once, at school, as 1st prize for compiling one in French. I haven't done any since, though, nor does it interest me.Quote:
110 is the number six in binary - the language of computers. And the bus just happened to be parked outside a computer shop, and the reflection of its name is clearly visible in the shot. So the binary number 6, with the reflection (mirror-reversed) of the word "computers" saved the shot for me. I did consider cropping the number plate out, but that was the number 363, not the number six, so I left it in intentionally.
If you ever get bored with photography, compiling crosswords might appeal.110 is the number six in binary - the language of computers.

Not recently. Isle of Man broadband is far from broad. I think it would be painfully slow.Have you thought about online storage?

The house didn't burn down, but the PSU developed a fault and caused a fire inside the case, which trashed both disks, and vented a lot of smoke out through the exhaust fan.
Personally, I wouldn't use the word "safely" in conjunction with any solution that has all the data inside one case. Or even one building, really - but you pays your money and you takes your choice. There's no single right answer to this one, sadly. Like how good a picture is, "safe enough" is very much in the eye of the beholder.
Point taken. I'll retain my motley collection of external drives as the back-up.George Lazarette wrote:

Thanks for all the suggestions. I'm really looking to be able to archive a lot of images and some video files cheaply.
I don't expect to be burgled, or for the house to burn down, so I think that the most convenient way to safely store data is on hard disks, with each original file on one set of disks and a copy on another.
Obviously there are several possible solutions, but I don't want to spend more than I need to.
Because the disks will not be used very intensively I don't expect them to get massively hot, or for them all to be running at once. I'll probably set them to be powered down after 20 minutes of non-use, so most of the time they will be taking no current and generating no heat.
That means I should be safe enough with up to to six drives in one case.

And enough space between the drives to let air move, and some fans to move it.I might perhaps need a new case, with a good power supply.

I dont know if its normal or not,but my pc has space for 6 drives inside. I run 2 off the onboard port which leaves me 4 free. A pci raid card allows you to run 2 more drives,so with 2 cards i could run 4 drives. If i was to do it again id go down this road filling the case with 500gb drives giving me at least 2tb,a possible 3tb all inside the case nice and neat.
OK, I get you. So I can simply add a RAID board, and slot in as many drives as I have room for?

I went the server way,its a big bulky thing i got cheap of ebay,its crammed full of hard drives,1.5tb,but if i could go back id go the other way and just buy large hard drives and a couple of raid cards.
I don't understand what you mean by buying large hard drives and RAID cards.I went the server way,its a big bulky thing i got cheap of ebay,its crammed full of hard drives,1.5tb,but if i could go back id go the other way and just buy large hard drives and a couple of raid cards.
Wouldn't they need to be located either in the computer (so you're back to using a server), or in a NAS enclosure which would have its own RAID card.
Or do you mean buy a new, fast, PC with the capacity to hold several drives? In which case, wouldn't RAID be on the motherboard?
I'm not very well-informed on this subject, hence my question.
