This is a very useful spradsheet done by Jhon Lane showing all lenses
I’ve been a google lover for a long time, and this love only increased when they bought Picasa.
I use Picasa to catalogue, search and view more than 50,000 picture and have been using the beta of version 2.5 for quite some time and I honestly think it has improved.
I recently happened to need a photography model release form to make it sign to someone. So here I was on the net searching and looking for such photography forms and I ended up by findind a few.
John Williams created a community where us, photographers, can share,find and provide details about our favorite photography places such as landscapes, panoramas, wildlife, wildflowers, waterfalls, cityscapes, canyons etc…
