I have a Fujifilm IS100. I would like to convert RAW to DNG and TIFF to DNG. Could someone advise me what software I would need to do this.I presently have have Lightroom 3.6 and Elements 4 (I am sure you can see I am on a really tight budget), when I export DNG from Lightroom it ends up in My Pictures as a PSD file, I open it and it opens in Elements 4. I have deleted Elements 4 and the PSD file will not open at all. Do I need another package other than Lightroom, like Elements 11?Barry Patman
