I just got a used Polaroid 545i off of ebay and I"m excited to start shooting. My main goal with polariod film is to have the prints as original pieces of art. I'm planning on shooting color, sepia, and black and white.

I'm confused about the black and white though since there are so many types. I"m debating between type 52 (iso 400) and type 54 (ISo 100). The confusing thing to me is that they say type54 will match a color chrome, which to me means prints with more contrast, due to the limited range of transparancy films. Type 52 looks like it's made to determine exposure and mimic true black and white film. Is this all correct so far?

Which do you think would be better for just the prints? And which do you think would be better to check exposure for true black and white film? Also, I've heard weird rumors about needing to clear Type 52.. like with a brush or something? Is this true?
