Compact fluorescent lighting

Bart: EV differences 1.3 does make sense, as I'm often switching between 1 and 1.5....

>waving grass ghosts are removed/reduced< True, but sometimes beeing blury. I couldn't figure out, how it really worked, but one might ask on the HDR-photo mailing list: http://www.hdr-photography.com/pipermail/hdr-photo

Klaus: You forget to mention, how long the entire stitch takes, including all...

Hard to tell, Asher
with leaves, I found it sometimes difficult to avoid "ghosting"
Usually in Photomatix Pro I use 3 or 5 images; so depends all how much the leaves are moving, within one exposure, too. But the other day, it matched even a tree with expositions about 10 secs as longest shot.

Klaus: Photomatix' upgrade has some improved features, as gammaslider, etc...
This app is very well supported and maintained.

Hey Mike, Bart!

Shame on me - i didn´t realize that 2.4 is out. I was using 2.2.2 - and didn´t care much with aligning to be honest . . . . am used working it over afterwards in PS.

But i tested it at once last night and i must say: it works well!

Thanks again - i don´t know when i would have realized it . .

best, Klaus

P.S.: Michael, the stitching takes mostly arround 15min. Editing about 10min and rendering depends on the size. Rendering of the 80MPx-picture of the cubical building with Spline64 and smartblend as TIFF/16bit took about 20-30min on my Mac - i didn´t control the time exactly.

Time depends heavyly on the machine you use and the space on the partition you reserve for APP.
APP supports my double-processor MAc and supports up to 8 CPUs and i think cores also.

Great program!

best, Klaus

Now, you' re teasing me, Klaus ;-)

I had been using/playing arround with other pano-apps, and spend a lot/to much of time, to get it done; therefore I didn't used it regulary. But I saw yesterday, that APP uses all 4 cores of my Quad....

a Distagon 28 on FF would produce - as a one row-stitch, imcluding 5 shots - a image having 110 x 65 degrees...
The nodal point should be corrected for 107.5 mm

did you do a 110degree rendering? I´d be interested in the quality of the outer regions! It´s interesting - the kind of rendering has a big influence in that. At such big angles, i prefer to render at max. 50% - because the plan-projection sometimes produces similar problems as extreme shifting does and decreasing the size of the final-rendering as planarprojection diminshes visual problems in that regions.
At the moment i´m testing a way to photograph one picture with two lenses: a 20mm for the inner regions and a 50mm for the outer regions (of course a bigger amount of pictures to fill in). The effect is, the stitcher/renderer doesn´t have such extreme projection-corrections to outer edges while rendering a planar projection.
A friend of mine does it this way - he´s working with APP quite a longer time as i am. And it´s workin very well.

best, Klaus

No time yet....
I only calculated the possible angle.

And off course you' right about the outer regions week aspect.
But heck, I'm not a dedicated UW-shooter. On the 4/5, I rarely went wider than 65 mm, loving the 90 or 120....
So, If the distagon works fine for a 90 or 100 deg-angle, I'd be pleased.

Klaus, did you ever had the PSA from Zörk? It gives a pretty outstanding files, at 65 x 42 cm/300; I sometimes use it with Hassi lenses, for (architecture) modell shots, too. On the 80mm, distortion isn't a problem, but as I found out how to correct distortion of the shiftet lenses; I'll try that 50 mm first; here's a test with it:

maybe some jaggies, through downsampling....

Hi Michael!

Looks good!
No - i never had that Zörk. I use a 4x5" view (Linhof) or a field (Wista) camera for architekture with shift. Or sometimes a SWC or a 6x9 Silvestri. Sold the Silvestri and bought the Wista instead. I´m just selling the SWC also - too much limitations. I can do it with my 6x12/17 camera more flexible.

best, Klaus

P.S.: how did you scan the shot?

Which scan?? They' re just screenshots: (apple+shift+4)
