Two for the price of one! I've done some tweaking on my recently build Loch-Lomo(aka Agfa Clack Pinhole conversion) I thought i had the pinhole a wee bit big at about .5ish mm.
Some quick Googling about Focal Lenghts vs Pinhole sizes came up with some interesting answers and programmes to calculate the correct size and another 10 minutes later i had reduced the aperture to around .36mm . In terms of cameras it's still way short of .376mm that is the ideal for the 72mm focal length of the agfa , but it will suffice(i know, i know , i'm german, and we are precise and fastidious and accurate blah blah blah......but if i wanted accurate and really good engineering I would buy a Leica. But then again, the pinhole is designed to be a little soft and gentle; so it would still fall into the above'i'm german etc' category as a precision instrument that does exactly what it is designed to do...quid pro quo, status quo is maintained...ergo: i'm happy!)
For this weeks edition of POTHW I have used one of my test shots from my tweaked pinhole camera 30 second exposure on TMX100, developed in d76(1:3, 15min) scanned and just slightly adjusted curves as the image was just a little too bright and sharpened to compensate for the scanner. all in all an acceptable result for me. next step is a few rolls of colour
