DSLR images shot direct from above.
« on: December 29, 2010, 05:01:03 AM »

Hi all, Found this forum today and it looks like it's right up my street.
We print digital vinyl cushion flooring. My question is this:-
We need to shoot a series of natural flooring images, Sand, pebbles, cobbles, Snow, cracked mud, Tarmac, grass, water and the list goes on. Any ideas will be welcome of how this can be done. Obviously I have my ideas and thoughts but it would be good to get some fresh new ones.
One thing I forgot to say that is important the final artwork whether stitched or not needs to be a minimum of 13ft sq (4m) square.

When I shoot more than a few large rugs I build a platform out of 2x4s and plywood and tilt it a few degrees and use a large rolling metal ladder with a tripod strapped to it. How controlled a situation are you planning to work in?

How 'bout a couple ladders with a 2x12 between them? Or a Gitzo super tele studex with a cross arm?

What's the big deal? What am I missing?

Hi David, The large rolling ladder idea sounds good. I plan to work with the seasons as we get a clear day start shooting in the spring, and keep it rolling through the year. I was thinking of investing in a video camera boom so it is easy enough to move around and get a series of shots than can be stitched. Thanks for the feed back.

Hi Chris, I'm just about to have a look at the Gitzo super tele studex with a cross arm, excuse lac of experience shooting location work. I'll come back to you when I've taken a look.

Hi Chris, Checked out the Gitzo super tele studex, looks like its been dropped as a product on there site. I get the idea though and understand were your coming from. Any more say 9ft high level rigs will be more than welcome. Like the "bout a couple ladders with a 2x12 between them"? comment, It would actually work well in some cases. Not sure I would want to carry them far though. :)

Bummer 'bout the product changes.

How 'bout this Gitzo, with this center column and this side arm?

I was thinking of investing in a video camera boom so it is easy enough to move around and get a series of shots than can be stitched.

Yes, it's similar to what I wanted to suggest. Some stitching programs specifically allow to assemble images of flat objects taken from different locations (e.g. PTAssembler for Windows, the Camera Position Optimizer in the Beta version). It relaxes the requirements for plan-parallel shooting tremendously (as long as the image plane is within the Depth of field), and thus allows faster aquisition.

Cheers,
Bart

You didn't mention equipment. Presuming digital, I'd want MF for maximum resolution and detail and a wide-angle lens. The wider you go (without distortion or bending) the less you will have to elevate it.
This, by the way, sounds like a great marketing idea for flooring.

Hi Ron, Great someone that gets the concept, I'm glad you like the idea. I have been looking at MF & DMF, I was thinking off shooting of somthing like. This http://www.google.co.uk/m/search?site=images&gl=uk&client=safari&source=mog&hl=en&aq=f&oq=&aqi=g1-k0d0t0&fkt=893&fsdt=4085&q=video+boom#i=4  Let's chat so more about the concept.

If you use a WA lens, you won't have to get as high, but you will have to extend it quite a bit to avoid getting the boom itself in the shot, so I would think the Hague would be best. Looks very solid too. A DMF will give you maximum resolution, and having a WA lens allows you to get closer to the subject for even better control over lighting and more detail. I would flood the area with external lighting, even when shooting outdoors, use the lowest ISO possible and trigger the camera with a remote for mirror-up function.

I'm excited by your idea and think it will have a strong appeal to high-end users. You might also consider shooting a clear flowing stream for people to install in their hallways. I can images a shutter speed that would show movement, yet retain details of streambed rocks and slower water. How cool would that be?
No matter what you use or where you use it, photography is all about the light, and having shot quite a bit outdoors, I suggest you flood the area with strong lighting from at least two sides to avoid shadows. Even with the sun directly overhead, you're going to get shadows from ambiant light.
If you shoot water, however, you'll also need a good CPL to avoid hot spots and flair.

Or this http://www.b-hague.co.uk/hague_hdv_boom_k8.htm

Booms don't lock down firmly. If you have to touch the camera, then there will be slight movement & change to the camera's position. If that's not a concern, and you want to shoot video, then go for it.

Also like the idea of running streams. Let's see what we can do :)
