grow up, ffs. if you can't handle alternative definitions of abstract photographs to your own maybe you should be more
specific.<div></div>
the best jokes have a punchline and the effect is immediate and most people wouldn't want to hear the same joke twice
(unless they didn't get it first time). the best photos, imho, don't have a punchline, the effect is not immediate and they can
be viewed many times.
<i>Are there any objective criteria that apply to the evaluation of abstract photographs</i>
<p>
many(as in the case with normal photos). the number of regular polygons visible in the photo, for example. but do we
really want objective criteria?
from wikipedia
<p>
<i>According to CIPA guidelines[2] 35 mm equivalent focal length are to be calculated like this: “Converted focal length
into 35mm camera” = Diagonal distance of image area in the 35mm camera (43.27mm) / Diagonal distance of image area
on the image sensor of the DSC × focal length of the lens of the DSC.</i>
<p>
so the crop factor of your camera is 43.27/(229xsqrt(2)) = 43.27/323.85 = 0.1336
<p>
which gives a 35mm equiv focal length of approximately 20mm (153.86 x 0.1336)
i used the 10D with an adapter from cameraquest and a contax-yashica 2.8/35. i liked that combo. i didn't do much manual focussing through the viewfinder but relied on hyperfocal distance
