Timing

Notes: All times calculated as an average of four operations. In record mode the "live preview" image comes back (in FAST REVIEW mode or by half-pressing the shutter release) about 1 second after taking the shot, you can take a shot almost immediately after this (around 1.5 seconds) for up to 8 images (filling the 48MB buffer)

The timings below represent time taken to "take and store" the image.

In playback mode the camera displays a rough (blown up thumbnail) image first and starts to decode the more detailed image in the background (which is why there are two timings for PLAY mode) you CAN move to the next image BEFORE this is decoded which means you can very quickly flick through images.

File sizes

Notes: All file sizes as an average of three files. As is the case with JPEG it's difficult to predict the size of an image because it will vary widly depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect. The reported JPEG compression ratios for the various JPEG image modes are: FINE (1:4), NORMAL (1:8), BASIC (1:16)

The estimated number of images per 8MB CF card is give as a guide to beginners (as an 8MB CF card is supplied with the camera). It is always recommended that you get a larger CF card, shame Nikon supplied such a small card with a 2 megapixel camera...

Battery life

Battery life is a very variable thing, and as most digicam users will know using ordinary alkaline batteries such as the 4 AA's supplied with a digicam won't last you long enough to fill up your 8MB CF card. This is of course true of the 950, fortunately I have two sets of GP 1300mAh NiMH rechargables.

On a shooting test I took both sets freshly charged on a Maha MH-C204F charger (visit Thomas Distributing) with a 48MB SanDisk CF card, I managed to fill the card and a 16MB Kingston in about five hours (around 180 shots) before the first set ran out.

That's pretty good going really, about the same (possibly a little less) than the 900s. Bear in mind that I used the LCD most of the time for composing the shot but normally turned it off between "shooting sessions". There was also a ten minute period of reviewing and deleting images over lunch.
