Re: OT: Fisheye for HDRI capture

[Philipp Oeser <philipp.oeser(at)liga01.de>]

regarding the fisheye:
if I'm not mistaken (correct me if I`m wrong) you only get full 180° in your pictures with a full cirular fisheye-lens and the last time I looked into that the common ones were made for full size CCD-sensors (35mm)
The D80 doesnt seem to have a fullsize CCD and therefore you propably wont get full 180°...

if you have 2 (better 3) full cirular 180° (vertical & horizontal) you can convert to latlong and quickly layer/merge/clonestamp them in photoshop (painfully slow with loading/saving hdrs imho) or krita (linux only)
there might be faster workflows (please post them!), though...

software to consider (all free except HDRShop):

converting from fishey to latlong:
HDRShop (MirrorballCloseup>Latlong) [ >> is there a _free_ alternative out there for this step?]

Thanks guys for your tips!

I'll keep the mentioned points in mind and keep the traditional sphere handy as needed.

These are the lenses what are available to me. Is there a particular one what you would reccomend? Another point is the circular vs. non-circular. I have'nt managet to get my head around that yet, which is better for hdri capture. Local photo guy reccomended very highly first lens in the list, the Sigma AF 10mm F2,8 EX DC Fisheye.

I am using Nikon D80 for all the work. Another part is software, with that I mean stitching and ldr merging for making hdri. While shooting in raw it is not so much issue, cause the amount of pictures what are needed to take comes down conciderably but still I would like to make the process as fast and error free as possible(who wouldn't). Is there some particular software to reccomend which can do this work automatically or semi automatically?

Bull, what kind of setup are you using to capture series of f stops automatically? You just using the remote
control and take various f stops manualy or you have managed to automate this process somehow.
D80 should allow capturing with predefined f stops settings three raw pics automatically in bracket mode but i have not tested with it.

Thanks,

The only thing with some fish eye lenses is that you can get lens flares 
on the edge of the frame. This can get a bit of an issue afterwards when 
stitching the shots together.
