Hi Joan-ramon,

 

The major critique for your flower anaglyph would be for something called retinal rivalry (R/R).  There is definitely color R/R caused by the colors in the image being too close to the colors of the Red/Cyan filters in the 3D glasses used to view the image. 

 

A possible second type of R/R is caused by a difference in lighting between the Left and Right image that makes up the pair.  This can be caused in a couple of ways but most common when using the cha cha method, allowing time between the capture of the left and right image to change its lighting conditions. 

R/R can also be caused in a cha cha or even a sync'd capture simply by the angle at which the light reflection from an object is caught in one lens compared to the other.  

 

If the R/R is not too drastic, a solution is to clone the offending portion of the image from one chip (L or R picture) to the other.  SPM now has a clone tool, or you can use another software such as Photoshop.  These applications can also help with the color rivalry by either de-saturating the color or changing the hue.  The image could be grayscaled (black and white) if desired.  SPM also includes a menu item that tries to match the brightness between chips.  This is helpful for that condition but more may be needed to fix others causes. 

 

Note: When using that feature in SPM to match brightness, use the X key to switch the Left and Right chips so that the best lighted image is on the left side before matching brightness since SPM tries to match from the left to the right side.

 

Final note:  Try to anticipate or in this case where the subject is "set up" under a controlled environment, "plan" ahead so that the colors are not blue or red.  Sometimes even other colors may cause retinal rivalry but by far it's normally Red and Cyan or blue.

 

Cheers,

Brian
