What was the success rate with the filter? It seems difficult to gauge what the hell you're taking a picture of with a macro filter on the Holga.
I'd say probably about 70%. I think there was 1 or 2 more besides the ones I posted from this particular farmers market visit that I decided were too blah. I have a little piece of string I carry with the filters with the focus distances marked on it for each filter. So I hold that up against the edge of the filter and stretch it towards the subject to gauge the distance (that's really important in making these turn out as well). Honestly, I don't even look through the camera viewfinder for most of these since I can kinda guess what should be in the photo based on where it's pointing and the string. Did you ever get the set I had sent to you for Christmas? : /
