I like the bottom left one of the swan thing (I think?) - looks like it's smelling the water. Or something. <em>Lionel: It was wintery and cold, I assure you. Very cold, in fact. Oh, and the young swan was drinking.</em> Cor, these pictures are lovely but they all look very wintery and cold!

Assuming you're using the SLR, you should be able to up the ISO to about 1600 or 3200, but you won't need to go to that extreme - probably only a 400 or 800 will do you. Basically, upping the ISO increases the 'sensitivity' of the sensor (it's not quite that simple in a digital camera, in that the sensitivity is always the same, but that's the common phraseology) so that more light hits the 'film', which means the shutter needs to be open less time in order to get the same amount of light. It should mean you get more light on the image. If necessary, you can also play with the shutter speed, so if you up the ISO, then keep the same shutter speed as before, you should get more detail in the finished photo. Or something. <em>Lionel: The gull was at ISO 400, the other three at ISO 200. I think I was being over-optimistic by hand-holding a 300mm zoom lens in poor lighting condition and f5.6 was giving me far too shallow a depth of field. I should have left the ISO at 400 or upped it to 800 as you suggest. The 400D offers me a range of 100 to 1600, btw</em> From the look of the bird photos, I’d say that you need to mess about most with the ISO.

Basically, upping the ISO increases the ’sensitivity’ of the sensor (it’s not quite that simple in a digital camera, in that the sensitivity is always the same, but that’s the common phraseology) so that more light hits the ‘film’, which means the shutter needs to be open less time in order to get the same amount of light.
