Hi I am interested producing HDRi 360° panos as per those on this site. http://www.hdri-locations.com/faq.php It would be apreciated if anyone could give me some info on the "high resolution HDRi map and matching backplates". What are HDRi files and can Autopano Pro produce them? Also what would be ment by "matching backplates"? I currently have a 20D but have ordered a 5DMkII. I have a sigma 8mm fisheye, would this lens on the 5DMkII be OK for 11500x5750 files? I have a half homemade/Realy Right Stuff pano head that works quite well. My son is into car design and wants me to produce some of the above files for him. I don't think he knows exactly how to use them as yet but he is researching it. Thanks in advance.
APP can produce HDR files. A backplate is a photograph into which the modeled 3d car will be placed. The HDR shot is used to light the car in a realistic way. You don't need 11500 x 5750 sized images, that was just an example of the image sizes they get with their equipment. If you want to know more about HDRi, its pointless for me to duplicate what has already been said on these forums countless times and what there is plenty of information on on the Internet, I would suggest you start with wikipedia or google http://en.wikipedia.org/wiki/High_dynamic_range_imaging If you want to know what resolution you can expect from your setup, use an online fov calculator, like these: http://www.worldserver.com/turk/quickti … ators.html http://www.tawbaware.com/maxlyons/calc.htm
Thanks for that I have a reasonable understanding of HDR photography and have combined exposures to produce a jpg or tiff file but have not come across a .hdr file that is used for lighting. I have not been able to find out exactly what a backplate file is, is it the full 360° rendered image or portions of that image? if using a fisheye lens is it the defished images? or do I take the same scene with a normal lense but not as a 360° but as a normal pano? Thanks in advance
So the point of a backplate is to impose a car onto it, and the panorama shot from precisely the spot where the car will be standing is used to make the lighting on the car and reflections all look real.
So you want to find a nice spot to show off a car (e.g. road curve in a forest), decide where exactly the car will be placed, shoot a normal photo of that view as if the car was already there, so your clients or son can superimpose the car onto it, and then go to the spot wherever you imagined the car to be standing and shoot a 360 from there.
Would be nice if you showed us what the end result will be
