Here are two viewers, a color chart with accurate measurements and two gray scales.
The two “L” shaped pieces are held together with clips found at Dollar Tree. You simply combine them into the size you want and clamp them that way. A simple, portable view finder.
View finder number two was a bit more complicated. I tried to follow the measurements on Clive’s you-tube video, but could not see them very well. My sizes are these:
Two 5 x 5 1/2″ pieces of matboard.
Two 1/2″ pieces 5″ long.
One scrap piece to fit below the window.
A scrap piece which fits snugly into the window slot.
Begin by cutting an identical square opening in both pieces of the 5 x 5 1/2″ pieces of matboard. My square is 3 1/4 by 3 1/4″. Mark out your window and cut it out of both pieces. Mine is not centered lengthwise. The bottom is 2 1/2″ while the top is 3/4″. I did this to give me a larger area to hold onto while using it.
Take the pieces you cut earlier and glue them to the backs of one of the viewfinder pieces (the pieces with the holes cut from the centers). You need to place them about an eighth of an inch from the edges of the cut out square. You will have surrounded the window with a frame on three sides, the left and right side and the bottom. Like a “U”. Leave the part directly above the cut out square free from any additional pieces.
Before you attach the other half of the view finder to the one you just glued the stuff to, cut a piece of matboard which will fit in that opening with a half inch sticking above the top of the viewfinder. Using a standard hole punch, punch a hole in the top of that piece of matboard. Check to make sure the matboard piece will fit securely within the viewfinder, yet be able to be pulled in and out easily. If all is well, glue the back onto the part you added pieces to. You are good to go. The punched hole in the slide gives you a viewfinder for tones or colors.
I hope that made sense…
Another quick and easy art supply. Gray scales.
These are wonderfully useful tools in your artist tool kit. If you can nail down tonal ranges, you have the hardest part of creating art in my opinion.
And finally, how to measure you color amounts:
When mixing we use the 1 + 1 = your color. Each amount is called a part. The problem is people often cannot understand what a “part” means. This chart will help you do that. You laminate the chart. Using a clear piece of glass (say one from an old picture frame) you lay it on top of this chart. Each line becomes your “part”. Simply fill the line in with color, add another color in another line and mix together to create your color. Or add as many lines of color as you want, it’s up to you. This is simply a way to measure consistently.
Each of these tools can be used very effectively in your personal art practice. The simple “L” view finders and a gray scale are going in my Plein Air box. I may add a coat of varnish to the more complicated view finder, as I often have paint all over my hands and don’t want to wreak the mat board.
