many of you have already successfully created HDR panoramic images.
i like to creating a HDRI.map for 3D Maya use, with IBL technique (image base lighting)
just wondering if you can give me some tips on shooting, perticular on my setup
Setup i have is
Nikon D200 + 10.5mm DX fisheye
Papywizard on Nokia N800
i like to take 13 angles all together.
in portrait orientation. 12 angles of 360 degree surround
1 angle of up right of the sky.
they will be bracket to 7 exposure for each angle, so at the end i will have 13x7= 91 shots
1. Nodal point for my setup
2. preset for this shoot
thank you all in advance!
The D200 with the 10,5mm needs 6+Z=7 shots for a full sphere without Nadir (you donÂ´t need a Nadir for IBL usually - but you can retouch a Nadir-hole in Photoshop very easily). For hires spheres use 20mm or 35mm to get more resolution. I used 20mm on a 20D (1,6 crop) for quite a time and had 24 shots for a sphere.
You can find the NPP position for your 10,5mm here: http://wiki.panotools.org/Entrance_Pupil_Database
Basically thereÂ´s two ways to achive a "true" HDR sphere to use it in Maya for IBL.
1) shooting bracketed (of course)
2) importing the bracketed images into AutoPanoGiga and create stacks.
3) render them as .hdr or .exr to keep the HDR-nature of the file.
1) shooting bracketed.
2) importing the images into APG and create stacks.
3) render them as layers,
4) for saving, write a "%" before the name - this way each layer is seperately rendered using itÂ´s bracketed values.
5) give the seven (or more) layers into a HDR-app like Photomatix for generating a single HDR-image from the bracketed layers and save the result as .exr or .hdr
for importing it in Maya, Cinema4D or others.
