In case anybody is following my attempts to use photo and video editing software, here is my update after migrating to Win 7 from XP.
Videos that could not be read by Windows Media Player and Windows Movie Maker on XP are now readable by those applications in Windows 7. This includes the AVI format produced by my game camera and the MOV format produced by my Fuji X30. Whereas I needed converters (VLC player and Handbrake) on Win XP, these are not needed on Win 7, and neither is Quicktime needed as a standalone player.
I had wanted to keep Photoshop Elements as my photo editing program. I was using a very old version 3 which did everything I wanted it to. Version 3 won’t run on Win 7, and the only version of Photoshop Elements now available has many bad reviews. I switched to GIMP, free open source, and use XnView as the photo organizer, also free open source. I use Windows Photo Gallery for importing images from my cameras.
The drivers for my Canon Rebel XT are not available for Win 7 64 bit and the camera cannot connect to the computer like it did in XP. This was overcome by switching the Communication Mode on the camera to Print/PTP. The camera was then identified by Windows Photo Gallery.
Using XnView as the front-end to GIMP works almost exactly the way the Photoshop Browser worked in relation to the Photoshop editor. The only thing lacking in XnView is a timeline view of images, as was available in the Photoshop Browser. XnView is folder-oriented. GIMP can be invoked directly from a selected image. GIMP to my mind is an improved version of my old Elements 3. So far, so good.
