Tutorial 02: Shooting Recommendations for Optimum Results

your first images, we recommend you to start shooting something easy like a stone wall and try to apply these rules below. Then go to more complex subjects when you gain experience.

What to do:
The photographer must shoot each subject 2 times,

  • Once facing the subject - that's your FRONT PHOTO
  • Once slightly more to the photographer's right side, still pointing camera to the subject - that's your RIGHT PHOTO

Example of imagesThe recommended subject choice for beginners is a stone wall as it's the easiest of all subjects

Recommendations for Optimum Shooting for Beginners:

  • The recommended angle between shots is roughly 10 to 20 degree
    • you don't need to be too precise
    • lean to your right if close to the subject like 1 meter (4 feets)
    • side step to your right if your subject is at 3 meter (12 feets)
    • walk to your right to get the equivalent of 10-20 degree if your subject is further away
  • What you should do:
    • Shoot both images in the same action
    • Center aim at the same spot on the subject
    • Always control images on the camera screen after shooting
      • Flipping between FRONT and RIGHT photos should make the subject "rock" or "dance" like an animated movie. If you see that images don't "rock" because they are too different or if lighting (*) is different or something got in the way. Then it's better to shoot the sequence again.

        Control after shooting - Your subject should be rocking like this

      • (*) : see the advanced tutorial to lock exposure with your camera when facing difficult conditions

  • What you should avoid:
    • moving your camera up or down between shots
    • tilting your camera between shots
    • step-in or out between shots
    • subject that move between shots
    • insufficient lighting
    • inconsistent lighting between shots
    • flash
    • disturbing backgrounds behind your subject, uniform background is best
    • being too close to the subject, step back and zoom in for better results
  • Optimum subject choice:
    • textured subjects like stone
    • 2.5 D subjects like wood bark
  • Subject that won't work well:
    • shiny or mirroring objects like cars
    • complex geometry and objects on multiple layers like tree branches
    • too uniform surfaces with no detail like modern buildings
    • translucid and transparent objects like water
    • black objects or white objects
    • patterned surfaces

That's all you should be all set for your first 3d images now!

Tutorial 01 (Video): Software Discovery

PhotoSculpt Textures Video Tutorial

This short 1'46'' video shows you how to create 3D models from 2 photos of the same subject

For this tutorial, you need 2 photos of the same object, a FRONT PHOTO (sometimes refered as left photo) and a RIGHT PHOTO. We recommend you to use samples photos provided with the software for this tutorial.

Then launch Photosculpt Textures and follow those 5 easy steps :

1. Open or drag'n'drop your photos into the PhotoSculpt Texture interface

2. Click on the sculpt button. This starts the sculpting operation.

3. Stop the sculpting operation when enough detail is sculpted

4. save as 3D model or texture map using the tabs and the save icon

 Technical note: All textures and UV maping are based on your FRONT PHOTO only.

5. Import the result in your favorite 3d program, setup your scenes, cameras and lightings and launch a render

That's all for this tutorial, thanks for reading and watching!

You can now go to the next tutorial to get prepared to your first 3d shooting session!
