Put some paper on the work surface under the light, cover half (with a thick card, book etc.) and leave it there with the light on for about 5 minutes (probably 5 times longer than you will ever have your usual paper exposed) and process it normally. If you can't determine where the paper was covered and where it was uncovered your "safelight" is safe. If you can determine a difference you'll have to reduce the power of the bulbs and try again. I've got a 30 watt bulb in mine 3 feet from the developing tray and I've not been able to notice a difference in paper sitting under it half covered even after 10 minutes.

A Lens angle of view table from half frame to 8x10. Not on the diagonal but the horizontal long side which is far more useful. 2.

For running two rapid fixes on my film now i have a control sheet so i know when to throw a gallon bottle out or move it over. And a cost analysis again. It cost 7 cents a roll to fix a roll of film if you belive my numbers. 5. And if you are into rectangles; formats, i have an Aspect Ratio chart so you can get square or panoramic and anything in between and call it it's own special name! And you can see the formats drawn to scale for a visual comparison.

My own chart tool shows diagonal, width and height, so it serves all. I was going to make a comment that I've seen folks use a camera tilted for the diagonal to get in a large group, airplane, building, skyline or what have you. At first it seemed odd to use a camera that way, but now I see the sense of humour in it and sometimes do it myself for less serious photos. There are other measures, too, such as width of field, with the assumption that an 8x10 will result.

A shot from behind the catcher with the ump and pitcher making a baseball diamond. I did a shot like that myself and it remains in my family album 37 years later. (with a brownie Instamatic 100) Of all the different companies putting out the specs on their lenses, Hasselblad is the only company who listed the side by side angle as well as the diagonal! It matched our results from the formula we were appllying. All of the other companies just listed the diagonal angle. By the way we found out if you like using your 100mm lens on your half frame camera (18x24) and you decide to take that small step to 8x10 film: Your lens of choice would be a 1000mm one! If they make one of that exact length! Now that's easy to remember!
