I made this 8x10 black glass ambrotype of an old workmate's baby on commission a couple of weeks ago.
Everything went smoothly in this shoot. A nice clean plate (by my standards), even though she wriggled a fair bit during the 32 second exposure it still came out really nice even with a kind of 'soft focus' effect rather than the annoying motion blur you'd usually expect.
This was made through a 210mm Fujinon-W @ f/5.6 on my Tachihara 8x10
Light was direct sunlgiht through the loungeroom window diffused through a white bedsheet.
As I said in my other posts, 8x10's are a lot more natural to me now, easy to do, easy to develop. The workflow is very smooth with that format. Just need to apply it to my 11x14's with more practice!
