There have already been a number of reviews about Lomography's reformulated Lomochrome Purple XR 100-400 film. I thought I'd throw my hat in the ring and share a bit about my own recent experience with this unique, specialty film.
I've only shot one roll of this new formulation so far, so I'll refrain make any unwarranted claims that go beyond my personal experience. What I have observed is that the new film seems a bit more subtle, and less grainy, than the original version. In a word, Lomo Purple has matured as a product. That's a good thing, considering it's not exactly cheap. It still gives you that faux infrared look, though, which is truly unique among color print films.
The degree to which the purple effect came out in images varied according to subject, and the amount of light in a scene. Greens, most prominently, are rendered as rich shades of purple. Back-lit daffodils took on beautiful pink hues, regardless of whether the flowers were actually yellow or white. In shade, as one might expect, the purple tones were darker overall.
The following examples were all shot at EI 400, and home developed using a Unicolor C-41 kit. The camera used was a Canon EOS Elan IIe, with a Tamron SP 24-135 f/3.5-5.6 zoom. Unfortunately, this camera seems to have developed a light leak, which I corrected for by adding a little vignetting to some images. I applied all my usual edits: curves, dust spotting, some transform corrections.
