[alt-photo] Re: Prints on Aluminum- response

[Diana Bloomfield]

Hi Rajul,

Thanks for being so generous-- and with such detailed information.  I  
always assumed aluminum had to be "degreased" with something super- 
acidic, so I'm surprised to see that it can be prepared with such  
common ingredients (sandpaper, detergent, etc).   Although I'm sure  
the images "in real life" are even more impressive, these come across  
really well. I love the light and sense of movement in them especially.

Thanks again.

Diana
