Has anyone tried Irfan View? I ask because it is rarely if ever mentioned anywhere in the photography community but personally, mainly because Lightroom is a little slow on my PC and because it's great for quickly browsing and culling files pre-Lightroom import or Photoshop editing I find it indespensible.
Some of the functions I find useful are..
it recognises all Nikon, Canon and Sony Raw files (as long as you have plugin pack installed).
It quickly renders your image at 1:1 with one key press.
It runs in an uncluttered full sized window and you can browse in a full sized screen.
It can be configured to move/copy files to different folders with a multiple key press.
It has batch conversion, resize, rename, copy and move functions.
I can be configured to export to Photoshop (with it's edit in external editor function) with a multiple key press.
It displays Exif data with a key press.
It's a small and completely clean install (just uncheck any boxes that sugget installing chrome or avg on the initial install).
It's completely free.
Draw backs are that the built in image editing functions are minimal and pretty much pointless.You need to spend a little time configuring it.
If you have a lightning fast PC that imports quickly and browses through files in lightroom or bridge without any rendering delays you probably wont benefit from it too much but if you don't and you want to keep your lightroom catalog imports as small as and as fast as possible or you want a picture browser that will quickly import files to Photoshop without having to associate files to Adobe software then it's worth consideration.
I'm not selling anything so if you want to try it just google it. (and don't forget the plugin pack so it recognises raw files).
If you try it, after you configure let us know how you get on. :-)
