We are alive and shipping

True enough.  We have been for a little while: a meter here, a meter there.  It's not kilometers yet, but we are trying.  There are a bunch in process.  We have resolved manufacturing issues.  Orders from here out will be filled from the new batch.

MetroLux II is still available, also.

Meter Sub-Ranging and Its Effects

The Pocket Spot Light Meter sub-ranges between 5 and 6 EV. This means that at less than about 6 EV, the meter changes from 1 degree to 3 degree reading. (To judge 3 degrees is the same as 1 degree, but use the thickness of the case. Remember that the actual spot is mostly square, not round as the site implies.)

To optimize meter sensitivity over the widest range, the Pocket Spot Light Meter subranges in two places: at the low end and the high end. For various reasons, the high end sub-ranging is not an issue and will probably never be noticed. But because we photographers are so interested in the shadows, there are times when the EV 5 to 6 range is very important. It is in this range that the meter sub-ranges, i.e. it changes from 1 degree to 3 degrees to gather more light.

So, what happens if the one degree shadow is surrounded by something slightly brighter and the meter sub-ranges? If it isn't that much brighter, the meter will meter the 3 degrees and that is that, but if it is several stops brighter, it will go between 1 degree and 3 degrees displaying a reading that oscillates between the brightness of the 1 degree and the 3 degree. This can be confusing, but knowing what the meter is doing can clarify the reading.

Oops, I dropped my Pocket Spot meter in the ....

We hope this never happens, so to avoid costly and untimely repairs, be sure that the lanyard is in good shape and the knot is tight and the appropriate knot. Always keep the meter secure.

First, if you should have a bad day and drop your meter onto a hard surface or run over it with a car. Don't worry, it is probably okay. It is not out of calibration. If it hit very hard, then it is possible for the electronics to break, but not likely. And they can be replaced or repaired as necessary. If the switch on the bottom appears damaged, don't try to fix it yourself unless you are in the Gobi desert. All other deserts, please contact us. Do not attempt to disassemble this meter. It is virtually impossible unless you know what you are doing. This is not a challenge, only a warning. Don't take the dial off as that will get you nowhere.

Second, if you should drop the meter into a fresh water. See if there is water inside. Although Pocket Spot is not waterproof, it is fairly repellent and should dunk be brief, it may be fine. Dry off the outside. Take out the battery and see if there is water inside. If there is water inside, you will need to send it in for repair. Do not put the battery back in place. Again, if you are in the Gobi and have no email, rinse the meter with distilled water and dry in a warm place such as the sunny dash of you car or a vacuum chamber.

Third, if you should drop the meter into salt water. See above and if there is water inside, then rinse it several times, inside and out, with distilled, reverse osmosis, or de-ionized water. Leave the battery out and contact the factory. If you get it in time, there is hope.

MetroLux II, End of Production

MetroLux, the compensating darkroom timer ends production

MetroLux, The Darkroom Lamp Controller,
get one while you can


MetroLux counts down for the last time

The last production of MetroLux IIs is upon us. There are a small number of units left for sale and that will be that. When they are gone, they are gone. If you have always wanted a MetroLux or think you'll want one in the future, then there is no better time than now to get one. We won't be making any more and used MetroLux are hard to find and almost as expensive as new ones. We won't be holding any back and there will be no more after this.

Prices

MetroLux II w/probe and instructions $369
Footswitch $45
Extra probe $45

Plus shipping and applicable taxes. Prices are subject to change.

Service for MetroLux One and II continues to be available, although for the One, some parts are scarce. This is not as scary as it sounds. To date, we have been able to fix all the Metrolux that have come our way. The return rate is very low. The Metrolux design has been and continues to be very durable.

Early Pocket Spot Baffles

Unpainted older metal baffle.


If you have an early Pocket Spot Meter, then the baffle in front of the lens (outside) will be one with several individual 'rings' made of anodized aluminum. If this is the case, there is an improvement to be done if it hasn't already been done. You should be able to tell. The edges of the rings, at least the forward most two, should be painted with flat black paint. Krylon UFB is the best, but most any will work. Put some on a Q-tip or paint brush, and go around those edges without getting any on the lens. This improves metering contrast. If you'd like us to do it, send it in.

If you have a baffle that appears to be threaded and made of plastic, then this is not an issue and you can sleep at night.

Pocket Spot




Here is the Pocket Spot in the rare red model. Most units are all black with white laser scribed writing and red LED display. Single LEDs on display indicate 1/3 and 2/3 addition EVs. The meter is 2.25" long and a little wider than 2". Body is 3/4" thick and the dials adds 1/8". Finish is black anodized over a solid block of machined aluminum. It weighs 4 1/8 oz (117 grams) with strap and battery, both included. EV range is -1 2/3 to 23 at 100 ASA. Spectral sensitivity is compensated for "typical" B&W film. Angle of view is approximately 1 degree. Viewing is by bore-sighting through the hole the length of the chassis. Battery is the 6V PX28.
