Today i saw an individual walking with 2 minolta cameras side by side walking around taking pictures of everything. I stopped and asked him what his setup was all about. He responded 3D pictures.?.? does anyone have any examples or experience as to syncing two cameras side by side. He seemed to only have to press the shutter on one camera but it would capture on both cameras. Any info would be appreciated but an example would be the best!
 
I know a guy tha uses 2 rebel XT's like this. his shutter release is a remote though

Yeah, that was me that mentioned it.

The results with the ($100) lens are AMAZING if you realize what you are buying and what it's for.

Traditionally, 3D pictures would be printed and viewed at a max of 4x6, so perfect focus and super sharp photos were really not required.

What I mean is: you are not critically examining the picture for perfect focus and massive detail, you are taking the picture for the sole purpose of the effect.

The effect (3D) ends up being WAY more important than anything else: composition / lighting / focus / etc.

But, if you manage to nail exposure / focus / etc AND have a photo that really "pops off the screen" .. it's amazing.

The lens is capable of being fairly sharp, but it's certainly not without its issues.

(They are coming out with a new lens next month that addresses many of these concerns.)

Personally, I find impossible to shoot "flat" photos after doing 3D. Instead of "viewing a picture" of your vacation, YOU ARE BACK ON YOUR VACATION.. standing there, just where you were, with the vista stretching out before you. It's amazing.

The big development by Loreo (besides the lens) is their new viewer.

This viewer allows you to pull up the picture on a 17" monitor, not a 4x6 photo. And, if multiple people are sitting around a screen, they can all see 3D at the same time, making for some very interactive family fun. I went to the zoo recently and got some amazing pictures. When I pulled them up on a large monitor, my kids would laugh and scream.
Try THAT with flat photos! Impossible.

HIGHLY recommended lens!
 
Are you talking about pictures that you have to wear a special pair of glasses to enjoy the 3D efect? Thanx.
 
sadly after examining more and thinking back to my map and arial photography class, you do have to use either a stereoscope or a mirrorscope. No fun! i was thinking you could some how merge the photos to gether to give it a look as if it was popping off of the paper. Not so unless you have the glasses/scopes.

Actually, that's not true. If you take a look at the sample images here:

http://www.rpm.or.jp/home/h-kouno/3dphotose1.htm

you can easily see the 3D image by forcing your eyes to lock distant focus on the image pairs labeled "parallel view" - you "look through" the images until your visual cortex merges the two images into one 3D center image. Google "stereogram" to see a bunch of examples. It's a very impressive effect - cool products.

I actually think that we are talking here about two different things (and both are called 3D pictures) - the first one is when you take 2 pictures (right and left) and using special software you combine them into one and then view them using special glasses (ref eg. Photo3D 303 - they sell a complete kit).

The 2nd 3D is so called stereogram (haven't got a clue how you achieve the effect), and for this you don't need any special glasses, just focus your eyes into infinity, and that's really cool.

I presume the original thread referred to the first scenario (but I could be wrong).
 
Well, from someone who has focusing problems between my eyes, I can't for the life of me see ANY 3D stereo-type pictures. Even the ones with glasses aren't the best sometimes. However, it would be neat to actually try to see the effect this lens has on a big monitor.
 
I know a couple of people who cannot focus to infinity and I myself had problems at the beginning. Just try and try, it's worth it! Once you get it right, you will always get it right!

The contraption the OP referred to creates the 2 left / right pictures which you can view by laying them side by side and focussing your eyes "behind", or "through" them. The link I posted was for the product in the third post, which creates the same effect using a split lens device focussing two images on the film plane - er, chip. Here's a sample from the Loreo website:





Unfortunately, I can't figure out how to get DP Review to display them side by side, but the top picture should be on the left and the lower picture on the right. If you cut and paste them into a graphics program side by side with no or very little space between them, then focus on getting your eyes / brain to focus through them and combine the two images into one "central" image, you will see a very realistic 3D effect. Check out the website in my previous post for more cool example.

Here's a better example from the same website. If you look at the single top image, the clutter created by the branches and the building, and the similar color, makes it difficult to determine the true shape of the building. At least not easily.

Looking at the lower image pair, and allowing your eyes to focus past and through so you combine the two images into a stero image, the branches lift way out in front of the building, and it is much easier to examine the structure and design of the building. Way cool.

Yes, Loreo's new glasses are not the old red/blue kind.. just clear glass that force your eyes to see both images without trying.

Actually, it's a "box" you look thru, it folds flat for mailing / storing.

It's.. amazing. Again, old school 3D was a personal thing limited to staring down one small image at a time. These glasses allow you to see a 17" (or whatever your monitor is) image.. and 3 or 4 people can sit around the monitor at once enjoying it.

(BTW, I don't work for them, just LOVE their stuff.) :)
 
How do you view the images? Do you have to cross your eyes or wear special glasses?

Does it help to use shallow DOF to isolate subjects?

Can you stitch multiple images with this effect or it's only that one shot?

Is it just me or are these images in the example way too small to see/appreciate. I have no problem with the 'looking to infinity' to view them but the pics are tiny and can't appreciate anything. Instead of one 3d picture, I'm seeing 3 pics, the one in the middle being the '3d' one.

How easy or difficult it is to "lock onto" the 3D image seems to depend on a lot of factors involving the size of the monitor, the resolution, dot pitch (?) and other stuff, at least for me. At work I have a 20" Mitsubishi high res CRT monitor, and the images I posted of the oriental temple and the trees snaps into the 3D view without too much effort. At home I have this little 15" Dell LCD and it took me almost 10 minutes of staring at the d@mn thing to get the image to snap into place. I have no idea why.

When it does snap into place, what I see is a very clear and distinct central 3D image - clearly 3D, no ambiguity at all - with two faint, ghostly images, one on the left and one on the right, almost out of the field of my vision. (My face is about 7 to 8 inches away from the screen for this to work.)

Doing this on the screen at home does induce a bit of nausea, by the way, which never happens on the monitor at work. I have no idea whatsoever what kind of processing is going on in the visual cortex to make this work, but it's clearly making my brain work harder at home than it had to on the screen at work.
