Face and Body Scanning / Re: Mounting cameras to light stands

« on: May 15, 2014, 12:47:21 PM »

Just looked at your suggestions Lambo, would those allow me to mount the camera like this (see attachment, excuse poor mockup).

Just looking as some other Arkon stuff on Amazon maybe these would allow me to mount the cameras at the angle I want?

Regarding these: http://www.cullmann.de/en/results/cat/klemmen.html - They look ok but as they say in the description they are only designed to hold a light DSLR with lens. I need it to be able to hold 600D and 1100Ds

Hi

I've tried a few of the handle bar clamps and they didn't allow me to position the cameras with enough precision. Also could only mount camera portrait.

Thanks all for your replies on this. So

Manfrotto Super Clamp 19.95
Manfrotto MA492 Ball head 28.00
Manfrotto Adaptor Spigot 7.95

Total 55.90 UK pounds

That price is fine if I only want to do it for one camera, but for multiple cameras it becomes very expensive. Is there a cheaper option ?

Thanks Mark

Thanks for the reply, but I assume thats just a clamp? I'll then need to buy something to actually mount/adjust the camera angle ?

Hi all

I've been using tripods in my setup but they take up too much room. Ideally I'd like to mount my cameras on light stands, say 4 or 5 cameras per stand. Can anyone direct me to some good clamps that I can use to mount DSLRs to lights stands? Looking for something that's sturdy, adjustable and above all doesn't cost a fortune.

Regards Mark

Hi

Assume you've read my post Masking Hair from last week? I'm experimenting with not actually using background masking and just using the quick selection tool in Photoshop. Although with 100+ images it becomes a bit of a nightmare. This process also requires you to think about what what your actually masking, part of someone's hair can look very different from one angle to another and it's this thinking that's really slowing the process down for me? The only good thing it allows me to mask inside areas where previously photoscan would just leave a white patch.

Looking forward to a magic fix!

Ah i see Lambo. Sorry Wishgranter, I thought you were walking about the Magic Wand tool. I'll give it a go.

Thanks Mark

Hi

As I said, does the last image need to be taken any further to be used as a mask? Does it need to be solid white on black? Sorry I'm at work at the moment so can't actually test any of this.

Mark.

Hi

My experiments with the quick selection tool haven't been good, also trying to to it for 100 plus photos would be time consuming. Surely difference masking gives better results ?

Hi Admir

Ok I've just got an random image off the internet test this. Image 1 - original. Image 2 - Difference mask. Image 3 desaturated. Am I looking to lose all detail after this stage and have a completely white on black image ?

Thanks Mark.

Hi

Can you explain the difference blending method? Load your photo and background into photoshop, put the background on the top layer and change it to difference blending, then what do you do ?

Thanks Mark.

That sounds like a quick way of doing it, thanks. So do you prefer that method over photoshop ?

Hi All

I'm using background masking in photoscan, which on the whole works fine, but it does struggle around peoples hair. I try to get the hair as smooth and as flat as possible, but certain areas such as where the hair meets the neck causes problems with masking. I always end up with some of my white background within the mask. This in turn ends up on the photoscan model as white patches in the hair. Is there away around this besides manually masking each image in photoshop or could I using difference masking/keying in photoshop to get better results?

See attachment for problem I'm getting

Thanks Mark.

Hi sounds good. Yes my images are in tif format, they come of smart shooter as .cr2 files. Forgot to mention that a have a turntable setup where I need to use background images for a range of photos. For example, camera 1 would take image as as follows:

01_01.tif, 01_02.tif, 01_03.tif, 01_04.tif

camera 2

02_01.tif, 02_02.tif, 02_03.tif .........

And so on. So how would I tell photoscan to apply 01_01_background.tif to all images that camera 1 has taken ? and not to touch camera 2s images.

Thanks Mark.
