I find it more convenient to use the Olympus Viewer 3 program which for some inexplicable reason was not included with the E-PL5 (but can be downloaded from this link). The filters can be applied and reset and the final selection exported a JPEG file.
I have changed my work flow a bit. I used to to import and convert RAW files into DNG with Lightroom, discarding the RAW files, but I think I'll keep them around from now on, this can be fun.
Today is Saturday, meaning it is also CATURDAY!, one of the myriad Google+ photo theme days, so I have a photo of Paris, using the "grainy film" filter.
