Thanks! I'm not sure there's much more I can do to make things in my favour. The only question I have is with the software I use to stitch the image together (I have to scan the 4x5 in two passes and stitch it). When it stitches it it only allows for exposure compensation with low dynamic range. There's no other option for me to select. The exposure should be the same on both so I'm wondering if I might possibly be losing dynamic range in my photo- but maybe I'm just overthinking pinhole in general. Oh- I'm going to write a thread tonight about a virtual viewfinder app. I've been in contact with the developer and he's Gerry rigging his app to provide not only a preset for the harman titan pinhole and it's three cones but also since the iPhone's camera isn't wide angle enough for the 72mm cone he's working on adding on support for external clip on iPhone lenses that will provide an accurate wide angle viewfinder. I'm going to write it and post it later tonight when I have a chance and I'll send a copy to mike walker at walker cameras. Being able to actually get a decent idea of what your pinhole is going to see would be fantastically helpful, esp with the 150mm cone. That picture above I was convinced was framed to only include just the head. It was literally inches away using the 150mm cone and still I got a lot of the background. I honestly don't know how the extra background even got into the frame. It doesn't follow the angle of the cone at all and seems to bend physics to me.
