I'm so damn sick and tired of these so called radical Canonnites and
Nikonians preaching about how Canon is better/Nikon is better..
...
this is a very simple posting........hoping to maybe see some GREAT
photography, but as expected the same people coming on here posting
negative commentaries about wrong forum, or who cares?......WTF???
I've post on both Canon 1d and Nikon D3 forums and the same type of
responses occurred. So instead of just posting your best photo, and
let your photograph do your talking.....you'd rather hide behind you
computer and continue with the usual B.S.
its a damnnnnnnn shame.
Thanks for the in-depth explanation of your lightning photo.I do all my lightning with the 1D Mk II for the following reasons....
1) The lock button!!!!
2) The long exposure noise is very well controlled and no DFS noise
reduction is required.
3) I am not as concerned with rain. I am still concerned, just not
as much.
The lighting stitch was my first attempt at stitching lightning. To
do this I needed a very strong storm and we happened to get one the
night I took that shot. The storm dropped something like 100,000
strikes in 2 hours on the East Valley. It was amazing and a target
rich environment. NOTE: I try to stay far enough away, I can't hear
the thunder. Still a bit dangerous, however.
I shoot with a short telephoto like the 85mm f1.8 set to f5.6 to
f8.0. ISO is set to 200. Shutter speed is what-ever. I like 8-10
seconds.
Over the course of about 8 minutes, I took about 60+ pictures of so.
Since strikes were coming from this cell every 4-5 seconds, I would
get 1-2 strikes per shot. I worked from right to left making sure I
got 1 "dark frame" (a frame with no lightning in it, only ambient
light) and a few shots where the lightning never left the frame and
was well centered (more on this later).
The camera was in Landscape mode and there are 5 "groupings" working
right to left.
When I got back, I grabbed all of the frames that had well centered
lightning. I needed dark edges to aid in the blending. Also, if a
strike left the frame, it would just look weird.
I used the dark frames to subtract out the light from each lighting
shot. This left me with just the light added by the lightning and
nothing else. In most of the 5 groupings, 2 shots were combined
using the following formula:
![]()
The Base represents the "dark frame". 'n' was 2 or 3. I don't
remember the "x" value off of the top of my head. I wrote a quick
and dirty Cocoa app to do this for me.
I then stitched as normal using PanoTools and blended manually.
