Just Shoot Me - 27 Aug 2007 04:02 GMT

I am wondering why pictures I take with my Nikon do not have straight edges
unless
I take them in the mode for display on PC. I did not notice this setting on
any DSLR camera's yet
and if DSLR's regular settings can do it with out the rough edges why does
my camera have that extra setting.
I guess I am just worried my pics might have rough edges - like the cat
whiskers pic in another thread.

The cat whiskers was resized down in our web browsers, forcing temporary
aliasing artifacts. This is not a problem for normal resizing and use.

Please show an example or two.

What do you mean "I take them in the mode for display on PC"?
Which one would that be?

The cat whiskers seem like rough edges due to, ah, non-intelligent
resizing.

on my camera it select where it says PC on image quality.
1024/768res
i am pretty sure I still had the rough edges after resizing in adobe
photshop elements
when taking pics on the other settings.
perhaps on my nikon i would have had better luck shooting in RAW and letting
Adobe handle the resize.
instead of first the camera doing it and then adobe. 1 time resize might be
better than 2.

Ah. 3:4 crop, 0.7 Mpix (well, there were cameras with 0.3 MPix,
but any reasonable digital camera can deliver that ...)

Please show an original and the result after resizing with that
problem.

Please state the exact settings of the resizing tool as you
resized.

Well? Have you repointed your web sites?

You are referring to a problem called "stair-stepping." This happens
when you resize pictures or display pictures at certain resolutions
using a particular camera on a particular screen. If you want to see
if the camera is really causing it, take a look at the original
picture at 100% zoom and see if the stair-stepping is still there. By
the way, this is also the only way you can judge sharpness.

What Nikon has a mode for display on PC?
