Re: What do mega pixels mean, with digital cameras?
Just to add a little more, photos displayed on the web are usually saved at 72 dpi (dots per inch) whereas when printing a mono laser printer prints at 600 dpi and inkjet colour printers print up around 1200 dpi.
As stated before, the lower resolution pictures display OK on a PC screen but print either very small (2.5 cm x 2.5 cm) or blocky when printed at 6x4 inch(standard photo print).
I always take digital photos at the highest megapixel setting as you never know when you may want to print or play around with the image. As an aside, most cameras save the image as a jpg file which is a compressed format and if you manipulate the image and resave it you will lose quality (by the nature of the compression algorithym used). If you're going to play around with the image, save it first to a tif file or similar, play around with it, then save it as a jpg file when finished.
With the price of memory at the moment, hard drives, flash drives and the availability of CD & DVD burners, I would always take the largest megapixel photo available and then burn them off to CD or DVD for storage.
Hope this helps a bit.
