Mist-erious forest

syamastro posted a photo:


Morning fog at the top of the escarpment in Hamilton, Ontario, Canada. On the
right side, the cliff goes 100m down sharply. I used my new lens - fisheye
Samyang 8mm - which produced an interesting effect of curved trees at the
edges of the frame.

Here is a full sphere panorama from that spot (beware - it is huge, 38 MB, so
it might take a while until you see it in color):

HSS everyone!

Foggy escarpment - panorama

syamastro posted a photo:


A full-sphere panorama (rectangular projection) of Hamilton escarpment on a
foggy morning. Stitched out of 9 photos made with the Samyang 8mm fisheye
lens and my DIY zero-parallax tripod head. (The 9th shot was made hand held
without tripod, to patch the nadir.) Stitching was done using free software
Hugin. The resolution here (16 megapixels) is slightly reduced compared to
the original shots.

Samyang fisheye for street photography: de-fished

syamastro posted a photo:


De-fished (rectilinear) version of my street photo with Samyang 8mm fisheye
lens. Faces and figures are very distorted here - check the face of the girl
on the left side, and the right leg of the person walking on the right side.
The original version (see below) produces much more naturally looking faces
and figures, making the Samyang lens very useful for street photography.

Testing Canon135L lens with AF extension tubes

syamastro posted a photo:


First test with my new cheap (from China) macro extension tubes with electric
wiring (allows AF and aperture control of the lens) with my Canon 135mm f2L
lens. The magnification of such a combo is 1.1:1. I used a flash (Canon 580
EX) attached to the camera with a DIY softbox. The aperture was f/16 -
probably too small, as diffraction effects were pretty obvious. The shot was
slightly cropped.
