Measuring Tiny Amounts Without Scales!

In this Friday Tip we look at how to measure those tiny amounts of darkroom chemicals without having to buy expensive scales. Yes, it's easy and accurate enough for darkroom use in our developers, fixers etc.
Common darkroom chemical weights by the teaspoon/tablespoon.
These are "flat" teaspoon and tablespoon measurements. Buy a cheap kitchen teaspoons measurement tool, flatten the chemical with a knife by running it across the measurement tool to get accurate measurements. (see Making D-23 on this KZfaq channel).
Chemical weight by flat teaspoon (tsp) or flat tablespoon (Tbl)
Phenidone 1 tsp = 2g 1/2 tsp = 1g
Metol 1 tsp 3.5g
Sodium Thiosulphate Penta. 1 Tbl = 18g 1 tsp = 6g
Hydroquinone 1 Tbl = 9g 1tsp = 3g
Sodium metaborate 1Tbl = 14.5g 1tsp = 4.8g
Sodium sulphite Ahyd. 1Tbl = 22.8g 1tsp = 7.6g
Borax 1Tbl = 15g 1tsp = 5g
Sodium carbonate 1 Tbl = 18g 1tsp = 6g

It's so simple! I feel a little dumb that I never thought of it. 😅 Edit: I'm a chef, not a photographer. Sometimes I write recipes, and I wanna get really accurate on dry goods without a gram scale, so this method will definitely come in handy. Thanks again! 😄👍

How exactly tf did the video help

@ShovelChef 3 ай бұрын

I'm gonna rewatch it and get back to you. But I'm pretty sure the answer is "use math."

@ShovelChef 3 ай бұрын

Yeah, basically, if you need gram-scale accuracy for a recipe, and you know the "visual weight" of the stuff-- a teaspoon or whatever-- this is how you can split it accurately, distribute it across different batches of other-- omg I just realized more things that aren't photography. 😏

@malachite072 If you can only weigh to 1g accuracy but you need 0.25g or 0.1g you can use this method by dividing the 1g accordingly.

Doesn’t it also depend on the density of substance for what it will weigh?

Is funny that calibrated spoons are sometimes more expensive than small digital scales. Bought one scale for 20€ and it is very accurate. I checked it with some calibrated weights...

@@PictorialPlanet indeed😂. I want to change to self mixing my chemicals. So may be it is a good idea to get s little scale... But your method seems to be good too..

I normally use scales too but I show teaspoon measurements to help those who want self development to be as affordable as possible. Back when I started darkroom work in the 1960s many used cooking teaspoons for their measuring. It was and still is quite adequate. As I explain in my videos you don't need calibrated teaspoons/ tablespoons as long as you use the same ones each time. You will find your own developing times for your measurements. However, I applaud your buying scales! It will allow you to make much more.

@@PictorialPlanet I like your approach to do things the easy way. Unfortunately my son took all old spoons when he moved out and my wife forbid to steal the newer ones for my lab work. ;) These measuring spoons seems to be more common in the english speaking world. Here in Germany i found a better quality (not cheap plastic but metal) set of them for 25€ at amazon and a scale costs just 20€… It is crazy how cheap (and bad sometimes) electronic devices are nowadays…

According to The Calculator Site, 1 gram = .17 teaspoon. Which is less than 1/4 teaspoon, or .25 teaspoon.

@Thechezbailey 3 ай бұрын

Teaspoons measure volume, grams measure weight. Some things will weigh a gram per teaspoon, others will not.

@BostilCensurado 2 ай бұрын

that looks like way too much to be just 1 gram for most things, its more like 10 grams

I don't provide advice on taking anything internally. Obtain the correct measurement from a pharmacy.
