As the first post on the photography sessions I'm taking for the Response dept at TOI, this one is on focal lengths. The best way to illustrate this is with the 12x zoom Sony DSC H2. Check out the series of photographs to understand how 'zoom' gets distant objects 'closer'...
Photos are all shot on a tripod out through my window (it was too hot to visit the terrace for this) and saved in irfanview to reduce file size (dimensions are same as original). click on the photos to see full size. Check out more information on the photos on their flickr page linked
here.
