Some people call this the Neapolitan Rock, but I know that's not the correct name ...

Here is my humble rock photo I took yesterday, on Worldwide Pinhole Photography Day.

That's not humble, that's an excellent shot, pinhole or not!
How large can you enlarge a 4x5 pinhole negative like that?

Hi DMR,
Thanks for the kind comments.
I haven't had the opportunity but 4x5s can be enlarged to "mega size", certainly larger than 35mm film. Type 55 film in particular is very fine grained, with excellent range of tones. Maybe someone more knowledgeable will reply with their experience enlarging 4x5 negs.
One day when I build my own darkroom....

Thanks for the kind comments.
You're very welcome.
I know that 4x5 negatives can be enlarged to billboard size if needed.
I'm curious on how large is practical from that pinhole-exposed shot, as I know that many pinhole shots look "soft", but yours, at least from the contact print, looks much sharper than most pinholes I've seen.

These 4x5 pinhole shots are definitely more sharp (at the center) than my other pinhole images from smaller-format cameras. But taking a closer look at the type 55 prints, they are still soft in a pinhole sort of way - creamy/dreamy.
I like it, and it may still be quite nice blown up. If I ever get a decent pinhole negative on 4x5 and darkroom access I'll have to give it a try.
thanks,
