D40 and HDR

hello, I am looking forward to buying my first dslr and trying out some hdr photos. I really want to buy the nikon d40 maily for its price, quality and size (size is important here) but I've just learnt that it doesn't do bracketing.
How would I be able to take hdr shots then? Would taking a single raw file and then adjust the exposure later in the computer be the only way? Or take exposures manually? I'd be glad if anyone could help me with this question! thanks!

You could adjust the shutter time across a number of shots to achieve what you want. A tripod would be a good idea as you want the images to align when processing them.

Bracketing is not really suitable for HDR as the available range is not wide enough to cover the entire dynamic range.

It isn't difficult though, simply put your camera into manual, set the aperture to the setting you want and then adjust the shutter speed to get the optimum exposure. Once you have that adjust the shutter to 4 stops under exposed, take a shot, move to 2 stops under, then optimum, then 2 stops over.

Check the histogram of the first and last shots, on the first one (under) there should be space on the right and the last one (over) should have space on the left. If either of the extremes are not showing space on the histogram wind the shutter up/down another 2 stops from that point and take another. Most of the time the -4 to +2 range will cover everything though.

One more thing, your camera will be set to increment 1/3 of a stop at a time, so 2 stops is 6 clicks on the shutter adjustment.
