The Dom's tips for photographic success include:

Good Cameras - we use Nikon Digital Cameras, the present mob being pictured above.  The D200 is a robust fully functioned work horse, and is supported by the equally impressive slightly less functioned D80.  The stunning Leica D-Lux 4 has taken over restaurant and building interior work as well as being good enough to take out on its own!  The P5000 (with wide angle attachment) now travels as a reserve.  All the Nikon cameras are 10 megapixel - Leica don't (need to) chhase megapixels!. 

Good Lenses - we have stuck with Nikkor because we think they are the best.  The 18-200 (with vibration reduction) is the workhorse and the 12-24 takes over the wide angle work for large buildings and small piazzas (hint- get the building you are interested in at the top or side of the composition to minimize parallax problems).  The 70-300 (VR) lens is ideal for corbelling (if you are into that).  The 70-200 lens is just stunning - super fast silent focus and super fast optically because of the extra light it drags in, and ideal for everything from poppies and stained glass to long distance views of cathedrals (but not for carrying around - it weighs over 2kg).  We also have a 2x booster insert for the latter which takes it to 400 (600 plus 35mm equivalent) which reveals amazing people on tower tops!.

Sunshine - particularly early morning (always the best if you can get up early enough!) or evening - no digital manipulation can simulate good sun lighting, and paradoxically the sun in southern Europe in late Spring / Summer is too strong for really good photo light for much of the day.

Patience - if for example the sun is behind a cloud, then wait for it to appear again - this photo of Fonterutoli and Siena came after a one hour + wait for the pools of light to do the right thing - and of course there was no certainty that this was going to happen at all.

Profligancy - or whatever the right word is for taking lots and lots of photos - digital enables you to get statistics on your side.

High Quality Originals - use the highest photo quality and size (pixel dimension) settings - to help in this the Dom uses mini disk drives which store up to 500GB of data.  Never delete the original photo file but work from a copy as you cannot go back to the original after processing.

Composition - there is no need to worry about framing digital photos exactly because if they are sufficiently large it is easy to rotate and crop them (and also remove parallax lens distortion in tall buildings etc) as the first part of the "darkroom" process.  

Time - we spend a lot of time looking for interesting photos, or often parts of photos, and then sorting them to find the best and putting these through the "Adobe Darkroom" (v7 of Photoshop Elements is now available).
