Re: capturing spherical HDRi's?
Hi Paul, i didn't took the time to read all the thread so you may get duplicated offerings.. For me, i got 4 different chrome balls scales … 3 inches, 6 inches, 9 inches and 12 inches.. (garden decorations) … that do all we need for us. Got my DSLR on one tripod and my chrome ball on another one. I even use my finder ring if i need to place it on a table or on the ground. Important thing is to have something that will allow you to solidify your chrome ball on the tripod. Like a screw or something. Because sometimes it gets windy and you don't want your ball to fall on the concrete… Or some blue gum paste to stick it… I normally shoot 12-15 exposures with 1-3 stops diffenrencial depending on my ISO setting.. From total black to total white. Of course proper white balance is better but you know you'll be grading them to match the grading of the actual material… so .. I now simply use photoshop with the new HDR merge tool .. Works pretty dam good. What is fun onset is how much we draw attention with our alien's setup … but we must get fast. I always ask the first AD 5 mins after shots are done without any lighting setup change. And i also ask them that the crew get out while i am shooting. Wich they normally understand pretty well. You let the creative go on the next location, and have the gaffers, electros, etc just waiting in the back!.. You must have a shutter remote so that you don't move the camera while pressing the shutter release. So you setup your focus, and without auto focus on…. you stand there clicking, changing f-stops, clicking, changing f-stop, etc… until you have all your LDR images captured. i also like to take a bad ass panorama just to see the set. I often do this with my mobile phone panorama application while they are shooting principal photography. Very usefull …. Always make yourself a good friend of the Director, First Assistant Director and DP …. they will let you do your stuff without hiccups then! hope it helps! sly Sylvain Lebeau // SHED V-P/Visual effects supervisor 1410, RUE STANLEY, 11E ÉTAGE MONTRÉAL (QUÉBEC) H3A 1P8 T 514 849-1555 F 514 849-5025 WWW.SHEDMTL.COM http://WWW.SHEDMTL.COM On 2013-01-15, at 4:27 PM, Paul Griswold wrote: Hey guys - I've been asked to help out on the show Film Riot, and one of the things we were discussing is creating your own HDR images.

Re: capturing spherical HDRi's?
You can shoot a chromeball with any kind of lens sort of well. Telephoto lenses are preferable because they allow you to stand further away and thus be a smaller object in the reflection on the chrome ball.

Re: capturing spherical HDRi's?
You don't need a macro lens, because you want to place yourself far away from the wall. The longer the lens (more tele) the less distortion and more detail your chrome ball photo will have.

Re: capturing spherical HDRi's?
It really depends how much time you think you will have on set. Most of the
times this can be a major issue, since they may need to move the lighting
setup several times in one day and you don't want to be the guy slowing
everything down!
the chrome ball is probably the fastest method and still does the trick. So
if you need to capture a lighting setup fast this will be your best bet.
Defently worth getting one in any case (garden mirror balls).

Re: capturing spherical HDRi's?
These days I use the chrome ball just for light positioning reference. For capturing the actual HDRI I'll use a fish eye lens on a DSLR, nodal ninja attached to a tripod and then shoot between 8-10 images (including direct above and direct below) covering the scene. Then load these into PTGui Pro and let it stitch them into a LongLat HDRI. Works like a charm. Both quick to do on set and quick to assemble when you get back to the office.

Re: capturing spherical HDRi's?
One thing you need to know before you shoot anything is what you want to use it for. If it's just for using the HDR image as a means of lighting (a low-res image is enough) then the chrome ball does the trick. Depending on the max resolution of your camera it might even be high-res enough to be used as a reflection map, depending on how close you get to the reflecting objects in your scene and on how blurry the reflections are allowed to be (the blurrier the lower res the HDR image may be to avoid visible artifacts/pixels). Also, I found it helpful the use a tele lens when shooting the chrome ball. The further away you are from the ball the more info you get on the circumference of the ball, and the smaller your own reflection will be in the resulting image. If you absolutely need to avoid the reflection of yourself (and camera ) you need to make two shots from different angles and paint yourself out later. If you want to use the HDR image also as a background you will need extra high resolution, and ideally no distortion. However, affordable chrome balls are never distortion free, nor will you get enough resolution from a single shot of the ball. The only option I have found (besides using dedicated hardware like the spheron camera) is shooting a panorama and stitching it into a really high-res image. Any lens will do, but a fisheye will reduce the amount of images required and time needed for a full panorama. Shoot RAW if you can (or whatever floating point format your camera AND your stitching software (or Photoshop) supports), image sequences of varying exposure are more time consuming, and light can change fast while you shoot - think wind and clouds on a sunny day, let alone the director getting nervous while you fiddle around endlessly in between shots on a stressful day at -10 °C.

RE: capturing spherical HDRi's?
If you can you should look into using a photogrammetric approach for lighting, meaning that instead of mapping your hdri to sphere you can build a proxy version of the set (geometry) using photogrammetry or an automated modeling program like 123catch to generate the geo (which you can clean therefor), then you can project your hdri (images) to the geometry it will be more precise than a spherical setup, but it is also longer to set up! And depends on the information and images you ve got from the set. Here is a video I saw some time ago, really cool stuff: (video is using maya and mari btw) its a 3 part video: http://www.youtube.com/watch?v=1d8ypguQjFw http://www.youtube.com/watch?v=pdEyQGzRSaQ http://www.youtube.com/watch?v=K3nPBrESJeE Hope that helps! -Manuel Subject: Re: capturing spherical HDRi's?

Hi, I've used this in the past for remote bracketing, works well http://www.breezesys.co.uk/DSLRRemotePro/index.htm Some other interesting bits on their site as well.

The Promote controller is less hassle, and less to carry around / worry about when on set. I have one and it's rock solid.

Re: capturing spherical HDRi's?
Thanks guys for all the info! I'm passing it all on to Ryan (host of the show). If you haven't seen it, Film Riot is a neat little show - especially for students who are just starting out doing short films. He covers a lot of low-budget approaches to achieving some really cool stuff. Mostly it's After Effects DSLRs, but occasionally he'll get involved in some 3D stuff too. I just wish shows like that existed back when I was in college! (though when I was in college Lightwave 1.0 had just been released) -Paul

Hey guys - I've been asked to help out on the show Film Riot, and one of the things we were discussing is creating your own HDR images. I know HDRLabs has a ton of great info, but I was curious to know if anyone else had any good info or resources on the subject that I could pass along. It's not something I normally do, so I wanted to make sure I was giving them up-to-date info. Thanks, Paul
