The bois­ter­ous gen­eral opin­ion on Higher ISOs is just that — noisy.

The higher the ISO when tak­ing pho­tographs with your SLR, the more noise it cre­ates. So all of the efforts we make try­ing to tweak and adjust our cam­eras for that per­fect light­ing, coun­ter­acts with the clar­ity of the photograph.

Thus, here is our plea to the cam­era man­u­fac­tur­ers: We have suf­fi­cient mega pix­els, we cer­tainly don’t need more (Since that is what seems cam­era man­u­fac­tur­ers are giv­ing us nowa­days‚¦). Instead why not give us bet­ter low light/noise performance?

It should be noted that some pho­tog­ra­phers, espe­cially fine art pho­tog­ra­phers, can use noise to their advan­tage in order to cre­ate a cer­tain feel. For the most part though, most pho­tog­ra­phers hate noise.
