Hey guys what's up,,
Yesterday we had a photo seminar about star trials photography using 35mm systems.
so i went home, and i was thinking what would be the most efficient way to use to use the P40+ for star trial photography when i get it ?!
let's not forget that the P40/65+ are limited to 1 min exposure time
but i think it doesn't matter at all, why ???
First of all taking a nice circular star movement would need at least 1 hour 30 min from my personal experience. if something went wrong such as a beam of light or a car passed by your camera it immediately trash your photo from a single exposure shot.
However, taking a contentious number of shots 30 sec for 1hr 30min would more efficient and then stack them using a PS CS4 action know as start trial link below

would be more efficient, in which you can remove any unwanted frames in the sequence.
now !! another problem, it would need at least 80-120 shot to have a nice star trial shot, so if were to use the full sensor resolution 60 mp or 40 mp would take huge amount of space and it would need a super computer for blending process.
Now with sensor+ technology in the P40/65+ ,,, taking a sequence for star trial shots would be the most efficient way for space and memory saving. :thumbs:
This is a shot taken by 5D mark II + 14mm F/2.8 II
the problem with this shot is that i had to use the JPEG mode for the sequence, to save space and memory on my imac, i couldn't blend 120 raw.
shots. but it turned to be that the 5D mark II JPEG processing is rubbish for both image processing and printing as well
your outputs, tips and additions will be so appreciated !!
cheers!
