it seems that i shoot many of portraits at the beginning of the month......
the 1stone is an 8x10 petzval on 8x10 aluminum. f11 for 4 sec. he asked for some artifacts...i tried to make a weird boarder but all in ended up with was the vignetting. i think the vignetting woks. i did have some trouble with my holder. seems to have been bleeding chemicals off the dark slide. i changed DS and fixed my problems.
the middle two are 5x7 using the above petzval. for about 1-2 sec.
the last is an 8x10 self pot. i used a 15 inch cooke and a packard shutter. seems based on my facial expression it takes some serious concentration to operate a bulb and count to 4! f8
