Nikon Coolpix P90 Camera review | Storage and Energy
Like almost all Nikon cameras, with the exception of some professional DSLR cameras, the Nikon Coolpix P90 is equipped with a card slot for SD and SDHC memory cards. This dual support provides a maximum storage that reaches 32GB, but you can also continue to use the 'old' SD cards. This capacity is ideal to leave standard in the camera. You should of course make sure to not lose the camera, so a backup of the card should be made in time. Those who think that the range of 32GB on a small SDHC card is the maximum will get a nice surprise in 2010 in relation to GB figures. From 2010, the first SDXC cards will be widely available, primarily with a capacity of 64GB and with a growth opportunity to 2TB! SDXC is currently not supported by existing equipment, which means this memory card is something for the (near) future.
Nikon Coolpix P90 memory
The Nikon Coolpix P90 stores its images in JPEG format. Too bad the camera does not support RAW format, which photographers are starting to increasingly require of a camera. However, the JPEG quality offering three different compressions is great for average use. The difference between a DSLR and a compact (mega zoom) camera, is clearly defined. The resolution of 12 Megapixels (4000x3000 pixels) provides a file size of more than 6MB per picture (highest resolution, lowest JPEG compression). The Nikon P90 features an internal memory of approximately 47MB which serves to store only 8 pictures at 12MP. Still, this internal memory can be used conveniently by storing pictures in low resolution on it. That way, you can carry and play a few hundreds of your favorite pictures (e.g. VGA quality) at all times.

Nikon P90 boasts a fast USB Hi-Speed port
The Nikon Coolpix P90 megazoom camera features a fast USB 2.0 Hi-Speed port at which high resolution files and in this case, also captured videos (maximum of 2GB in size) can be transferred to a notebook or desktop computer. Although the Nikon P90 is able to transfer these files with high speed through the interface, personally I prefer a fast (FireWire) card reader. I find it the ideal accessory that lets you keep on working with the camera and spares you the fiddling with a separate cable that has to be connected from the camera to an external device.
Nikon Li-Ion EN-EL5 battery
For the energy, the Nikon P90 uses a Li-Ion battery. The EN-EL5 battery has to be recharged through the included battery charger. This takes approximately 2 hours. According to CIPA measurements, a fully charged battery provides the Nikon Coolpix P90 with 200 pictures. In practice, the circumstances differ from the circumstances CIPA measurements are based on, which means fewer pictures can actually be taken. In our case, we took 185 pictures on one battery load (the ambient temperature, among other things, hugely influences the battery's performance). If you're likely to take more pictures and are unable to recharge the battery at all times, you may want to purchase an extra battery.
