how to put full 3D effect in an image?

Question

Can we put 3D effect in an image and watch this without using any coloured glasses ?

Answer

You are really asking two completely different questions.

1. Can we put 3D effect in an image?
2. Can I watch a 3D image without using any coloured glasses?

For #1, consider that 3D images are not a single image, the 3D effect is achieved by having two different images taken from a slightly different point of view. To see the 3D effect you have to feed these two images one to each eye. This approximates how we see the real world.

So really, if you have a single image you cannot see 3D. Though you can use post-production techniques to generate two images from your single image. This is how some 2D movies are "converted" to 3D.

There is good information about 3D imagery in the Stereoscopy page on Wikipedia.

Regarding #2, there are a few ways to see 3D images without glasses. But most require either glasses (to filter the two images being displayed and provide a single image to each eye) or specialized display hardware (to split the two images based on the angle of view each eye is at with respect to the display).

There is one interesting method that doesn't require any special hardware nor glasses and that is quite easy to achieve. It's commonly called "Wiggle 3D". This question has a pretty good example of this technique, and my answer there points to a tutorial on how to make them.

Is the Olympus EP3L a good choice for 3D Macro?

Question

I'm interested in getting an Olympus EPL3 for amateur use.

In order of importance I'd like to be able to do the following:

1. Macro 3D
2. General purpose; portraits and panoramas
3. Time-lapse

Is this a good choice of camera? What lenses would you recommend?

At a later date (a year probably) I'd like to try astro-photography, will adapters for four thirds to telescope become available at some point, or will I have to convert from 4/3rds to SLR?

thanks

If my underwater macros with the PEN2 are anything to go by, I would think that the PEN3 is as good or better for macro - with the kit lens. The picture I linked is of a 1cm large pygmy sea horse, and it is cropped. The resolution is amazing and I am sure you can easily fit two of them into the picture with a 3D lens without loosing sharpness or too much resolution. They are even selling some LED lights for macros. That should be great for on-the-go use.

In general I would say that the PEN models are very good cameras for all-round photography. You might want to take a look at the Lumix Lenses to get a bigger variety. I am very happy with the 20mm 1.7 prime lens for example.

Regarding Timelapse you might need to buy an intervalometer to control the camera. There are many models that let you shoot timelapses until the memory card is full and have tons of features. I am using this one here which does everything that I need.

What 3D lenses are available for a Sony NEX camera?

Question

I currently have a Sony NEX-VG10. I would like to know if it's possible or worthwhile to get a 3D lens for it? I did a google search and can't seem to find any — or am I blind?

Answer

It's certainly possible; your camera has E-mount; you could use adapter for A-mount lenses together with a 3Dstereo lens. Perhaps slightly more known is Loreo 3D lens, that comes in Sony/Minolta A, Canon EF, Nikon F or Pentax K mount and could be used with adapter for that mount. Or, you could combine an adapter for four-thirds and Panasonic 3D lens.

As for if it's worthwhile - only you can decide that. You can search for results others have achieved and think if it could be a worthy addition to your images/videos. Some find that a special camera (such as Fuji FinePix Real 3D W3) does the job better, mostly because the distance between lenses is closer to human vision, you have live preview of the result, control over zoom and aperture, and you have full resolution for both images.

For 3D photos of still scenes, an alternative is to attach your camera on a focusing rail on top of a tripod so that it can ride sideways, and using manual mode and manual focusing (for making sure nothing changes between frames) to take separate frames for left and right image, and post-process them into a 3D image.
