There’ve been a few threads about shooting reference images and creating IBL domes recently. And I’m considering to buy a few peaces of equipment for this as a christmas gift for my self. What I’ve already got is a 600D with a sigma 18-70, 2,8-4,5. And a tripod. So, for shooting reference pics all…

Biggest things are a fisheye and a nodal head. Get a nodal ninja 3 and samyang and peleng both do really good fisheyes for about €250. You don’t need a fisheye but it’ll cut down on the amount of angles you’d need to shoot from and speed is very handy if you’re on set (In that regard, a ricoh theta …

Thanks alot John! I thought the linearization would be an automatic prozess, hard to imagine how hard it will be to match all the colors and grey values. Grey values only could be possible though. The ball thing is funny. I think I saw them first in a making of of JP2, or was it LOTR1? Don’t know …

You think for an HDRI capture option you could get away with using a Theta S and this software, http://www.builtlight.org/simple-hdr/ ? I hate the time sink in capturing such a huge image set, stitching, and all that for something that gets used mostly for reflections… since you mention placing actua…

If I get a Theta S to shoot the domes. A luxmeter to mesure the brightness. And a chart for linealize the dome and some reference pics which I shoot with my dslr at the set (For material creation). Plus a grey and a mirror ball. Would that be a good starting point? And in chase of Material creatio…

Well if you have a few 1000s of $ to spare (± 18000) you can always go for a spheron VR: https://www.spheron.com/products/cgi-reality-based-visualization.html

Yeah the theta will shoot bracketed jpgs with an app - I think being able to shoot raw means you can shoot less brackets but will end up with a similar end result. The theta isn’t huge res but again if you’re on a film shoot you’ve no time and your 1st ad will appreciate you only taking 60 seconds. …

Very good suggestions here, i second them all. If you are looking to buy gray/chrome sphere instead of building them yourself, have a look at AKROMATIC ’s. We bought from them for a good price i think but i looked now and prices went up, a lot. I’ve to say though that quality is very good and we’re…

The theta seems to be the winner for me (assuming I’d have to rob a bank for the last two suggestions) So the list would be: Theta S Kodac q13 chart ND gel Luxmeter Homemade balls How would the linearlizing go? Linealizing the brackets first or linealize the HDRI? And I’m not shure how to rea…

No need for the nd gel with the theta, I don’t think there’s a way to mount it on the lens and you definitely can’t get in behind the lens before the sensor. In terms of linearizing it kind of depends what software you have access to. What you’d do is get the rgb values of each patch and then in li…

Spheron is producing cameras with technology from the last century. It can be slow as hell to capture under difficult lighting conditions.
I would recommend the Civetta from Weiss AG or the Lizard Q if you need even more resolution.
