This is a thread that explains digital camera processes and capabilities and, more importantly, why some cameras are like they are. This is an extensive thread that will give you information that will let you choose the camera that will best met your railroad photography needs. Thanks to Pete Nolan, Flandry and others for their input. Thanks to the TB membership for their questions. This thread will take some time to read and re-read, but it is well worth the effort BEFORE you select a camera. One of out best threads, IMHO.
