|Nikon D50 - RAW and JPEG
Images can be stored as NEF (RAW) files or as JPEG. There are three resolutions and three different compressions available for JPEG. If you shoot in RAW and JPEG at the same time, JPEG with highest resolution and the largest compression is stored. It is advisable not to use the highest compression unless you really have to. They show artifacts quite clearly. Best of all is to store in RAW file format. It will take up more storage capacity and it will take a tiny little bit longer, but it definitely delivers the best result.
Considering a 1GB storage capacity:
Resolution 3008x2000 pixels - NEF (Large) - 5MB - 132 images
Resolution 3008x2000 pixels - JPEG - Large - 2.9MB - 280 images
Resolution 3008x2000 pixels - JPEG - Medium - 1.6MB - 492 images
Resolution 3008x2000 pixels - JPEG - Small - 0.8MB - 1032 images
Resolution 2256x1496 pixels - JPEG - Large - 1.5MB - 548 images
Resolution 2256x1496 pixels - JPEG - Medium - 0.8MB - 932 images
Resolution 2256x1496 pixels - JPEG - Small - 0.4MB - 1856 images
Resolution 1504x1000 pixels - JPEG - Large - 0.8MB - 1032 images
Resolution 1504x1000 pixels - JPEG - Medium - 0.4MB - 1692 images
Resolution 1504x1000 pixels - JPEG - Small - 0.2MB - 3080 images
Resolution NEF+JPEG - Large - 5.8MB - 116 images
|Nikon D50 - Storing the image
A memory card with at least 512MB of storage capacity is recommendable, certainly with RAW format but more MB's won't hurt either. And if possible choose a fast card, storing of the images will take up some time, at least if you work with RAW. When using JPEG also a slower memory card stores the information rather quickly. Even that fast, the buffer hardly ever fills up completely. Shooting in the highest quality JPEG I was still able to shoot continuously with the Nikon D50. Until the memory card's capacity ran out of course. Shooting in RAW means that you meet the limits of the buffer fast. Only three RAW images fit into the buffer. And the speed of 2.5 frames per second is not that fast for a camera like this. Question is if the Nikon D50 user wants a speedy camera at all.
Nikon D50 - Battery
The renowned EN-EL3 Lithium Ion (7.4V 1400mAh) battery is used for delivering energy to the camera. A battery that we acknowledge as one with an enormous power. More than a thousand images shouldn't be a problem at all for the camera. Especially when you don't review the captured pictures all the time. I had problems trying to completely empty the battery when I was testing the D50. So if you take the Nikon D50 with you on holiday, you don't have to recharge the camera too often. Or just take a second battery along with you and leave the battery charger at home. Makes a difference to the weight you'll have to carry.
