OT >> at what res do the megapixels stop growing fast? Here's the calculation. Assuming you want to print a 4x6 picture of the current consumer ($300) ink-jet color photo printers on premium paper (20 cents/sheet), which have a 1200 dots/inch resolution. 1200 x 1200 dots = 1.4 M-pixels / sq inch. Apply 10x compression for MPEG, that's 0.14 M-Pix/sq inch. Multiply by 24 sq inches for 4x6 photo size, and you get approx 3.4 M-Pix. However, the 1200 dots/inch resolution of inkjet printers is approx 1/3 or the resolution of photographic paper. And now 2400 dots/inch printers are available. That calls for a 4x increase in pixels. So quite likely, the pixels of high quality cameras will creep toward 13 M-Pix, which is the announcement that started this discussion. Please excuse use of US currency. I think you are in UK, right ? Sarmad
