I am trying to do a simple reflection hologram. I have purchased several laser pointers on ebay, and 3d printed some jigs to hold the laser pointer and the film upright. The film I am using is the litiholo self developing C-RT20 film.
The laser modules I am using are just from ebay. 5mw red 650nm. They started with a line lens, but it screwed off to give the laser a somewhat flashlight shaped beam, which from my understanding is correct.
Here is an album with my setup as well as results in direct and indirect lighting.
I exposed for 4 minutes, and as you can see from the line across the bottom of the film, it did in fact get exposed (i.e. the darker part was obscured by the holder and didnt get exposed).
Anyone have any tips? Thanks in advance.
