Thread: Dog vision. Interesting simulation.

It's a fairly natural reaction Headcasee when your experiences with dogs, based 100% on how you see the world would find some of this hard to accept, primarily because you not in possession of the information of how they do work. When you actually understand the animal better, you train it better and the dog is more relaxed and accepting of lessons.

Here is some back ground information on that specific video.

This is a rough simulation I rendered through the eyes of a dog. A dog's eyesight is very limited to color in respect to what we see; they can see (a lighter shade of) blue and yellow, but cannot distinguish red and green. They also have a visual acuity (contrast) of much less detail than we do. It is believed that most dogs have an eyesight equivalent from 20/50 to 20/75, however they have been known to identify their owner at a range of 800-900 meters due to their ability to visually discriminate motion (impressive)!

BTW, this is my Labrador. His name is Wilbur!

(PowerDirector v12)
Visual acuity filter simulated through a configuration degree of "4" in the "Blur" effect filter.

Brightness effect reduced by a factor of 20% (this, however, does not account for lighter color tones, since there is a relative measure of brightness-detection with dogs due to their tapetum lucidum [a layer of tissue in the back of the eye which reflects visible light]).

For some reason, the recompiled video was slower, so I had to modify the length of the edited video to match the original.

Thank you for watching! As time progresses, so will my videos. Enjoy!

But let's look at the same information differently.


Before you jump and decide to make an internet dogs breakfast of a seriously important aspect of dealing with dogs... just think about this, and then think about how now knowing the strengths and weaknesses of your dogs vision how you will now be able to discern when they are using scent, or movement, hearing, or can see ducks after dark, or can't see something 20 feet away that is red..... The impact this knowledge makes is significant, but may seem subtle at first!

As you probably assumed... I'll have more for you.
