The Polaris SPD-100 Light Meter comes in this simple unassuming box. The packaging is very unassuming. Inside the box the Polaris SPD-100 comes with a carrying case, a lanyard, and a manual.
The meter is a nice size coming in at 2.5 inches wide, 7/8 of an inch thick, and 4 and 11/16 inches tall. The battery door is located on the back. The meter uses a standard AA battery.
When you turn on the meter the first thing the it does is a battery check. It shows this information for about a second. This is nice because if you are about to start a complex and lengthy shoot, you can just change out the battery rather than having to stop the process (model, assistant, etc.) and restart after changing a battery. Also, if the meter does run out of batteries, the meter will save your most recent settings as it does when you turn it off and back on. Another nice thing about this meter is that it automatically turns itself off after 5 minutes of non-use. Some people might not like this, however, it is a nice power saving feature for when you get busy and forget to turn it off.
The Polaris SPD-100 allows you to measure both incident or flash metering and reflective light metering. Reflective light metering is similar to the light metering included in your Digital SLR camera. Incident light metering is the ability of the light meter to measure a light incident such as the firing of the strobe flashes in a studio setup.
To use the reflective metering you first slide the incident sphere to the right until it clicks, exposing the light sensor. Then you press and hold the ISO button while using the adjustment buttons on the side to adjust the ISO to the preferred setting. Then you press the mode button until the ambient light metering mode displays. You can have the ambient metering displayed in F/stop and shutter speed or EV values depending on how you have set this.
You then point the meter in the direction of what you want to meter and press the measurement button. You are then given the reading.
You can also use this meter as an incident light meter for strobes in a studio setting. First you need to slide the incident sphere over the light sensor on the left. Then you adjust the ISO setting. After this you can chose to a corded or cordless flash mode. The corded flash mode uses a PC cord from the meter to the flash. Then when you push the trigger button, the flash fires and the meter takes a reading. If you use the cordless mode then the meter waits for you to fire the flash. When doing this the meter waits for your to remotely trigger the flash. In the video I demonstrate the cordless flash metering with my Nikon SB-900. I then demonstrate the corded PC Sync Flash Meter Mode with a CowboyStudio 180 watt second studio strobe. Watch this part of the video and you will see when a good meter is so important. The SB-900 gave different readings depending on how I set the flash and the Cowboy Studio Strobe gave different readings depending on how intense I set the strobe. The crazy thing was though, that when I adjusted the strobe down 1/2 a turn on the adjustment knob, the strobe intensity did not go down the same amount. Had I not had this meter, I would have not known this. Also, don't try to just take a bunch of test shots and review them on your camera's lcd screen. Chances are your LCD screen is way off on color and brightness calibration. Many camera's LCD screens are brighter than the picture actually is so you can see the photo when shooting in the sunlight. If you rely on the lcd screen to check your exposure, you could easily be underexposing every shot you take!
One down side of the meter is that when in Incident (Flash) Meter mode you can only adjust the flash sync speed or shutter speed and the ISO setting on this meter. There are ten different flash sync speed settings. Then, after you take the reading the meter gives you the F/Stop that goes with the shutter speed. If the reading is in between a full stop the meter will display this on the scale on the bottom the screen. The meter displays this in 1/10th stops. This is helpful for getting the perfect exposure.
You can also use this meter to set up multi-flash situations. This means that you can take a single flash reading, then select what F-stop you want to use and it will show how many times you need to fire the flash for that setting. This does not actually take multiple flash readings. It just does the math on-board to tell you how many times to trigger the flash for a desired effect.
Overall, this is a great meter for the price. It will not do what the $300, $600, or even $1000 meters will do. However, this meter is about $170 so to compare it to the more expensive models is like comparing apples and oranges. Most photographers will find this more than enough for their needs. If you do grow out of this you can either keep it as a back up or sell it. Look around online; these types of items are not cheap. Even used, they fetch a pretty penny. So, overall, I would recommend this product. I think you will be very happy with it.
Cheers!
