Have a look at Help-Camera for selecting a camera (specs)
the type of head will make no difference to camera, the thing that affects camera is material thickness. Set your camera calibration with a piece of material the thickness you will mostly use under the spot pattern.
I know that, for example, filming the course of a cut/etching without a filter will damage the camera.
The question is: Won’t the laser reflections while cut/etching damage the camera?
Yes, I can understand that. It has to do with the viewing angle of the camera, right?
I believe that the further away the camera is mounted, the more it eliminates this effect, but on the other hand, the accuracy is lower.
So, I’ve been looking at the camera table and I can see that in the “camera” column the number refers to megapixels and the letter refers to the viewing angle.
I can understand all the other fields as well except “Aspect”. What does this field refer to specifically, that I can’t associate the corresponding number with anything.
I notice that.
But, as I understand very little about cameras, I am not able to relate the value “1,333 or 1,778” with anything. Are you referring to some kind of scale?..
I can understand that a camera to work on a rectangular table (large and more industrial tables) has to be different from one to work on a square one, but that’s only as far as I can understand.
I apologize for my ignorance…
Not a scale. In simple terms it’s the aspect ratio of the sensor in the camera. You can think of this in terms of screen resolution. The 1.333 aspect ratio cameras will provide screen resolutions based on 4:3 aspect ratio size. This is like old TVs before HD. The 1.778 aspect ratio cameras will provide screen resolutions based on 16:9 aspect ratio size. Common HDTV resolutions like 1080P, 720P, 4K UHD are all 16:9 aspect ratio.
I didn’t exactly understand this relationship but I clearly understood the concept, which for me is the most important. More than that I have to go learn “image” or “photography”.
Now I know I have to look for one of the 1.333 because my machine has a square bed.
Many many thanks!!!
The extended axis kits often produce a Y-Axis that is twice as long as the X-Axis. This can make the 1.788 camera more attractive.
There is a Switch in Settings to turn the camera image 90 degrees to what is shown.
After the change to Settings, the camera can be rotated 90 degrees to make the image upright. This allows the theatre-width to be applied to the extended Y-axis. The value for the wide aspect ratio of the image will be inverted.
