Dosent the K810i have Xenon Flash? Shouldnt the image be clearer? N93,is a good camera, it is similar to the DSLR.

really? all i know is that N73 and N95 have too much noise reduction which means lack of detail.

while N93/N93i retains the original (and slightly noisy if in bad lighting) image which has a lot of detail, and one can always remove the noise via software if it doesn't suit the picture.

probably in earlier firmwares it was much more noisy? the noise seems quite acceptable to me.
however, after capturing an image with the n93, the image preview that is shown after usually is very very noisy because it is not a true preview, but sort of compressed and all (could be some bug in the image preview of n93).
if the image captured is viewed from the gallery of the n93, it is a lot better and doesn't have that noise in the image preview anymore.

i don't use any software to remove noise. i kinda like it.
the best part about noise is that, when the picture is resized to smaller sizes (like 640x480), the noise is not apparent at all and makes the photo look very detailed.
if the photo has a lot of noise reduction, when the photo is resized, the loss of detail is still noticeable, at least to me.
