Using a Photographic Enlarger : Photographic Enlarger: Grain Focuser


This is a grain focuser. And, in a way, this
was one of the hardest pieces of equipment for me to learn how to use in this darkroom.
And, what it does is, you actually put the focuser on the surface that you are printing
and it looks up into the negative. And, as you are focusing it, it lets you see the grain
of the negative. And, when your grain is sharp, that means you are in focus. Because it is
possible to print an image that you took in focus and you could print it out of focus.
And, there is, nobody wants to do that. So, the way the focuser works is again, you put
it down on the surface and very slowly you move this fine focusing handle up and down.
The way I learned to look for this grain was that it almost looked like if you had taken
a magnifying glass and put it over newspaper print. You start to kind of look for stuff.
And again, it took me a couple of days. This is also a precision thing. It is back to what
I was talking about before. You do not want to just guess. You really want to make sure
that that is in focus. After you have it in focus, you want to take this lock and lock
it down to make sure that focus does not slide on you.

  1. Hello Anthony, I'm no good at making videos but since you ARE I thought I'd make a suggestion so you (if interested) make your educational video precise; It is imperative people know about Adjusting the the finder. Some higher magnification grain focus finder models have adjustable eyepieces. To use one of these devices, you first need to adjust the eyepiece to your eyesight. This is best done in bright daylight. Many focus finders have a solid black bar or circle in the centre of the viewing area that is visible at all times. You need to adjust the eyepiece correction mechanism until the black bar is perfectly in focus.
    There might be a locking screw holding the adjuster in place, loosen it to adjust and do not forget to tighten it back once you are done. Make sure the adjustment has not drifted out of when locking it. Once adjusted, you will generally not need to touch it again unless your eyesight changes or another user needs to use the focus finder. Some focus finder models are designed to be viewed from a distance, and do not require viewfinder adjusment.
