Focusing loupe power

[Leigh B]

I've heard recommendations of 4x to 6x for ground glass focusing.

The Toyo is 4.6x, which seems to be pretty close to ideal. It's also long, so my nose doesn't hit the GG.

My Toyo is 3.6x magnification. It was the last version that you could get. My nose doesn't hit the GG either and I have a big nose!

[Leigh B]

OK. I have one new in the box and it does say 3.6x.

My other three were purchased used, advertised as 4.6x, but I've never checked them.

Thanks.

Shawn and I both use the Toyo 3.6 and like them a lot. They are a little hard to find since discontinued, but check eBay frequently and one may show up. I saw one once on the LF Forum, but it was gone before the person i told about it could buy it.

I have read that Toyo made a 4x loupe that you could change the focus.

I have a selection of loupes and the one I use is decided by the final enlargement ratio of the photograph.

For example if I'm enlarging 4x then I need at least a 5x loupe to have some focussing accuracy in reserve. If I'm doing a 8x10 contact then I don't need a loupe at all. The ground-glass is already showing me everything I will see in the final picture.

I'm not sure how this would work. Do you limit yourself to a particular print size for a given negative?

I frequently find myself doing multiple images from the same negative, usually crops or changing aspect ratio (8x10 v. 11x14 etc).

Yes, I use only two sizes of photographic paper, the aspect ratios are known before I start, and all cropping is in-camera. Then I go out and deliberately choose subject matter that fits those sizes and shapes.

[Leigh B]

OK.

So what happens if you do a landscape-format print, then a magazine wants to use it for a cover (obviously portrait mode)?

I've had that happen.

I shot chromes for many decades, so I'm well-accustomed to cropping in-camera. But requirements change.
