<p>[QUOTE=&quot;dougsmit, post: 2497575, member: 19463&quot;]Back in film days, I had a great preference for Black and White photography because th film allowed more different tones between black and white than did color films.&nbsp; Digital when saved as JPG images is limited to 256 shades from dark to light in each of three colors.&nbsp; Today we can work in 16 bit with vastly more steps from black to white in each color but still have to reduce to what our equipment will display.&nbsp; It does come in handy when were are stretching scales and might want to save extra tones in one end or the other.&nbsp; After we have saved a file in 8 bit mode, it is easy for us to lose fine differences between almost white and really white and there is no way to recover them.&nbsp; That is why we always save files in their original form as well as what we have processed.&nbsp; This makes much more difference for landscapes than for coins.[/QUOTE]</p><p><br /></p>
