Review: ViewfinderMasks

A custom viewfinder mask to save time and money

By Don Chick, M.Photog.Cr., CPP

Every now and then you encounter a product that falls into the category of “nice to have,” but for one reason or another, it just doesn’t make your priority list. Initially for me, a custom viewfinder mask was such a product. I could see the reason to own one and the potential value, but higher priorities and price kept me from making the investment of $195. Boy, was I wrong to delay!

Now that I have a custom viewfinder mask from ViewfinderMasks in my camera, I am convinced that it is one of those must-have products that will make your post-production life easier and pay for itself in both time and money.

A custom viewfinder mask helps because a DSLR, or 35mm camera creates a 3:2 ratio image area, which translates to 4x6 or 8x12 image formats, while most professional portrait photographers print 4x5 or 8x10 images using a 4:5 ratio. The composition and cropping problem happens when you fill the frame with your 8x12 subject (Figure 1) and attempt to print the image on 8x10 media.

you tend to fill the frame with your subject …

Part of the image must be cropped off at one or both ends (Figure 2). It is especially difficult to create a pleasing portrait when some of the head and body has to be cropped and the frame is filled mostly with the subject’s face.

The Viewfinder Mask I now use has the lines scribed on either end to indicate an 8x10-crop. When I create a portrait now, I almost never see the edge of the screen, but rather the lines. This has completely eliminated any guessing about how much or how little to include for the final image. Figure 3 shows the 3:2 ratio full viewfinder image and the final 8x10-crop image.

By confidently composing the image for the crop in-camera, you don’t have to worry that you’re not going to have enough room for cropping or that you’ve allowed so much extra space around the subject that you lose some of the camera’s resolution.

Figure 4, below, shows another ViewfinderMask option. With the mask oriented vertically, you can produce underclass or sports team portraits with every image having the identical head size. No more guesswork, no more post-production cropping. The dashed lines allow correct cropping for 5x7 images. From time- and money-saving perspectives alone, serious photographers should consider a custom viewfinder mask.
