    Accurate focus through enlarger

    I don't have that lope to find the focus so I use my eyes.

    Is there a way to make sure the focus is right. any technique?

    I tried focusing by eye for a while. It was frustrating. Also my enlarger was frustrating. A loupe makes it a lot easier, I would highly recommend one.

    But- at the same time of course - totally possible to focus by eye without the loupe. Don't have any recommendations except make sure the lens aperture is all the way open.

    Get a grain focuser such as a Paterson. In terms of focus still probably the best way and the Paterson one is the cheapest. Much more accurate than the eye

    I focus the enlarger by eye and then check with a focus scope and often find it is as sharp as when just focusing by eye.

    Tip: Focus the grain without paper.

    Or, use your 50mm lens reversed. Makes a great, super high quality, high magnification loupe.
