Example of sharper pinhole photo

[kevin klein]

Here is one, toy steam engine. Taken with Kodak 4x5 Tmax 400, open shade, 10 sec.
Developed with Kodak D19 8min. It is a good dense negative suitable for salt printing.

The print is on 8x10 Ilford rc paper.

I used to have one of those. Powered by methylated spirits under the boiler.
Now I wonder what happened to it.

Always wanted a toy steam engine, but the folks never agreed.

Pinhole photography doesn't have to be soft.

As I recall, you were using a pinhole WITH a lens. Is this image one made like that? If so, it's deceptive to describe it as a pinhole image. I don't mean to say it isn't ok to do it, I just hope that when you tell us what it is, you tell the whole story. Otherwise, how can we know what to make of it?

I too would like to know how you achieved such a sharp image, would like to try one myself.

The pinhole was placed between the lenses, the diaphram is closed down part way and the brass with p.h. is set on that and the rear lens screwed back into place. The brass has to be made just larg enugh so it wil not slide around too much. So it is more of an extreamly closed down f stop than anything but it does just exacaly what I want.

And that's what's important.
