Not sure what they are called specifically....
Quite often I see landscape photographers and more often filmmakers holding up a mask to assess the best viewpoint and composition before pointing a camera

Does anyone know what they are actually called and if there any websites that provide dimensions to enable diy make of some ?

Can't you cut a three by two hole in a piece of card?

Or you could extend the thumb and forefinger of each hand to form a rectangle.


Those that can, do. Those that can't whinge.

Yep I could, but I want to know dimensions and if they need to be specific to match different focal lengths etc. and know a technical term will help with googling....

1) Cut 3:2 hole in something flat
2) Go some where nice
3) Place flat thing with hole in front of face
4) Extend arm for tele, bend elbow for wide angle


In other words, it is not possible to assign a focal length to a certain size hole because your angle of view will be determined by the flat thing's distance to your eyeball.

I know a machinist who can make those for you for about $200. (Be sure to include a measuerment of how long your arm is.) By his choice of materials, they should last several hundred years, so pro-rated they would be cheap at that price.

And as you know, the reading from the reflected meter in your camera is heavily influenced by the tones in your subject, so I recommend that you buy my old incident meter which actually reads the light falling on the subject without that nasty influence.
Downside is that you'll have to run downrange several hundred yards (meters to you) to read that light falling on the subject, but just think about what wonderful shape you'll be in after a year of that! ; )

Go to a craft store and purchase some photo mat. 4x6, 5x7 8x10. It will give you what you are looking for.

I think they are called a director's viewfinder. It seems you can also download an app to a smartphone which does the same thing -

Many recent Canon cameras have this built in during Live View, probably the best way to do this, as you are using the sensor and aspect ratio indicators to give you the truest sense of what you are capturing.

So is everyone else who just looks through the viewfinder to get the angle of view & then looks at the subject to decide if that's the view that they want to include. ; )

Near the end of the article is the smart phone app which I was referring to - "Artemis Director's Viewfinder". Not sure how much the app costs but it would achieve what the OP is looking for.

The one I have is for 4x5 and has a tape measure you hold to your cheek at the marking for the fl of lens. Making your own would involve some trial and error unless you want to do a little trig.
