Somewhere around the 100th review, I got to wondering if the photos I was taking of review samples on my little digital scale were even accurate. Some folks I know pack their gear down to ounces, which caused an instant wave of paranoia to wash over me.
But calibrating a scale isn't difficult, and neither is buying calipers to augment the (sentimental) ruler I always use for my photos. So once it dawned on me to actually test my measurements, I set about to making sure what I am telling the world is accurate.
After waiting a couple weeks for my calibration weights to come, I was quite happy to find out that my scale was/is right on the money. I tried every combination of weights in the set, and the scale always shows the correct amount.
