Welcome to my world!

Hi guys! I'm roberta, a 23 years old girl from Siena, Italy.

After I graduated in "Visual Design" at University of Florence - Departement of Design, I work with enthusiasm as a freelance.

I really love graphic design and infographic: experimenting with colors&layout makes me happy, communicate through pictures is for me a rewarding job! Furthemore I loooove Photo Editing!

I always willing to learn more&more... this is for me the key to do it better! ^___^

Do you like 3d?

『 watch the pics with 3d glasses! 』

Stereoscopy, anaglyph and 3d perception
Stereoscopy refers to a technique for simulate 3d perception in an image by presenting two offset images separately to the left and right eye of the viewer: the anaglyphs precisely.
Anaglyph is a type of stereo 3D image created from two photographs taken approximately 6,5 cm (2.5 inches) apart, the center distance typically between human eyes. The Red color field of the left photo is combined with that of the right photo in such a way as to create the illusion of depth.
The first attempt to make a stereo-image with anagliph has been tried with success by Sir Charles Wheatstone in 1838. Understanding the operation of binocular vision, he built a stereoscope, which combined a system of prisms and mirrors to allow viewing of a three-dimensional image from a two-dimensional image.

Compared methods for creating anagliph with Adobe Photoshop
There are various methods to create anagliph pictures, here there are the "from two pictures" method and the "from 2d image" method. Let's try to explain both of them!

• The "from two pictures" method
  1. Place the camera in the tripod, make sure you have disabled autozoom and autofocus and take two photos, first take the left picture, and then slide the camera from 5 to 50cm (2 to 20 inches) to the right and shoot. To find right distance you have to try: consider 5 cm is the perfect distance for subjects between 2 and 15 meters (6 and 50 feet)! The perfect  focal length is between 35 and 50mm.
  2. Name the photo depending on the position "left" and "right" to avoid mistakes!
  3. Open the left photo, double click on the Background layer and rename it in "LEFT" and similarly open the right photo, double click on the Background layer and rename it in "RIGHT".
  4. Copy/paste the RIGHT in a layer above the LEFT.
  5. Double click in the icon of LEFT layer. This brings up a dialog box. Uncheck the red channel. Similiarly double click on the icon of RIGHT layer and turn off the green and blue channels leaving the red channel checked.
  6. You should now have what looks like an offset double image showing as a red and cyan mix with both red and cyan edges that are slightly offset. Most of the time when shooting a stereo pair with a single camera, these layers will have to be aligned vertically. To test your image, put on your red/cyan glasses. Look at the monitor image and see how things look. If you are happy with the results, crop the image to eliminate the overlap at the edges of the frame.

• The "from one pictures" method

  1. From your picture, separate the subject(s) from the background, using the Quick Selection Tool (W) and the Polygonal Lasso Tool (L) in the toolbar, trimming carefully.
  2. Now click on the Refine Edges button, up in the property bar and in the window that opens, set the Radius and Contrast values at ​​0 px, the Feather value at 1 px (this will give us slightly soft edges) move Smooth to smooth edges of the selection and lightly increase Expand to expand slightly better selection to enclose all the edges of the figure. When you are satisfied with the result click on OK.
  3. Click on the Move Tool (V) in the toolbar and press cmd + X (or CTRL+X) to cut the selection. Create a new layer and press cmd + V to paste the selection, and move it in the same position. Now you have your items on two separate layers.
  4. In the Layers window, create two folders, that represent the two depth layers. Rename them "Up" and "Down", moving the Backround layer in the "Down" folder, and the Subject layer on the "Up Folder".
  5. Now hide the Subject layer and using the Clone Stamp Tool (S) repaint the area inside the empty areas around the edges, pushing ALT button on the area you want to copy and then draw normally as if it were a normal brush.
  6. Now duplicate the backround layer and the subject layer in the respective folders. Rename the layers of the "Down" folder "backround_ right cyan" and "backround_left red" and the layers of the "Up" folder "subject_right cyan" and "subject_left red" (see the pic ☞]
  7. Right click on a layer and choose Blending Options, in the tab Advanced Blending uncheck the green channel (G) and blue (B) if the layer is a red or red channel (R) if the layer is a cyan.
  8. To see the anaglyphic effect, we must shift each layer of depth in an appropriate manner: select the "background_left red" layer and press for 5 times the LEFT ARROW key. Select the "background_ right cyan" later and press for 5 times the RIGHT ARROW key.
  9. Do the same with the subject layers, paying attention to the direction of the movement!
  10. Now you're ready to wear glasses and see the result!
