Make quick and easy jumbo size proofs with your enlarger. Fasten this beamsplitter to your enlarger lens so that you can meter the light with an ohmmeter. This will speed up the proof making process. Tip: Take a "self portrait" before starting to film color scenics. This becomes the "standard negative" for analyzers which are programmed for proper flesh tones. Tone matching the easy way. An easy-to-build light-sensing meter makes it easier to match skin tones from a variety of negatives. All about color analyzers. What is available and tips on their uses. Tips on taking exposure readings when making color prints from slides. Tips and tricks you may find handy in your color darkroom. (1) Conserving on paper. (2) Freeing film of fingerprints. (3) On-easel enlarger metering. (4) Warming chemicals. Build an enlarging comparator. A printing tool that expedites routine printing by eliminating the need for additional test strips or for making mathematical exposure calculations when changing print sizes. Est. cost: $25. Color analyzers. An introduction to how they work. How to use a color analyzer to determine the filtration needed when making color slides from color negatives. An enlarging light-meter for photographic printing incorporates a comparitor circuit designed specifically for photo work. Est. cost: $25. Enlarging exposure meter. Build a Zonal Enlarging Meter which tells how light or dark each area of the picture will turn out, based on a selected standard exposure time for your enlarger. Enlarger light meter aids in repeating good exposure. Build your own darkroom color analyzer. Determine the correct filter pack makeup and exposure timing before making the print. Est. cost: $15 and up. Darkroom printing meter for B&W papers. Repeatably good results can be gotten once an acceptable print has been produced at 10, 15, or 20 seconds exposure, using this meter. Enlarging Photometer uses five light-emitting diodes (LEDs) to indicate the direction and amount of aperture-stop movement needed to set enlarger lens. Easier to read than meters and cheaper than digital readouts. Est. cost: $10. Darkroom printing meter. Turn dial until two LED lamps turn on and you know the "correct" printing time. Estimated cost: $7-$15. Darkroom contrast meter tells you the standard contrast paper grade for an "average" negative. The meter covers paper grades zero to five. Darkroom light meter (spotmeter) for reading negative density. Uses surface-mounting assembly techniques to connect conventional parts. Setting up and using color analyzers. Some tips. Personal computer meets photography. BASIC language computer program does the necessary calculations to determine exposure times when making enlargements. Requires a densitometer to measure the highlight density of each negative to be printed. Program can select paper grade and calculate exposure time and f-stop for any size print. How to construct a beginner's photo enlarging meter. Operates at constant exposure time of 10 seconds. You change f-stop on enlarger lens to provide correct amount of light. A color film analyzer. Takes the guesswork out of determining the best color balance when printing from color negatives and slides to assure consistent results. Darkroom exposure meter measures the amount of light coming from your enlarger when projecting a negative. How to use the Science & Mechanics enlarging exposure meter. Includes modification of probe. How to use the Science & Mechanics darkroom meter to determine the proper paper contrasts for different negatives. Making your own standard negative for use with an enlarging meter. Tips on using the Luna-Pro light meter as an enlarging meter. Results of test with two integration type enlarging meters, the Patterson and the Spiratone. What to look for when buying a CdS enlarging exposure meter. Incorrect enlarger exposure meter readings may be caused by reciprocity law failure. Convert an inexpensive ohmmeter into an enlarging meter by attaching a cadmium sulfide photocell to the meter. How to use color analyzers to make consistent, high-quality color prints with a minimum of waste in time and materials. How an inexpensive color analyzer can help pay for itself. Some tips. Exposure meter for your darkroom work. What they can, and can't, do for you. How a color analyzer can make printing easier. Tips on using such devices. Using an enlarger exposure meter to speed the making of fixed-size enlargements at various magnification and aperture settings. Color negative film base and its impact on color correction when using a color analyzer. How to use a hand-held incident light meter in the darkroom as an enlarging meter. How to make a meterstick, a device used to determine the proper exposure time for prints of different sizes, once you have determined the time for a good print. Exposure meters for enlargers. What is available and tips on their use. Build a zonal enlarging meter which lets you measure any area of the enlarger's projected image and adjust the lens opening until that area is as light or as dark as you want it to be. Printing exposure light meter measures enlarger light intensity with accuracy and repeatability. Accessory for VTVM or TVM allows it to be used as a darkroom enlarging meter to indicate exposure times from 1 to 100 seconds. Enlarging exposure meter. Place a light probe on copy board and turn a dial to determine the proper exposure time for a given combination of paper and developer. Automatic photo enlarger controller picks up reflected light from the projected image and turns off the enlarger when enough light has reached the paper. Est. cost: $51. Build a wide-range photometer and enlarger exposure meter. A high-resolution instrument with 0.01-, 0.1-, 1.0- and 10-foot-candle ranges that are usable down to 0.0005 foot-candle. Neutral density filters extend upper range to 10,000 foot-candle. Exposure time ranges include 0 to 25, 50, and 100 seconds. Enlarging meter circuit uses a light-dependent resistor mounted in a tube.
