I have a zoom in my camera, optical zoom - btw never look at electronic zoom when you buy/choose your camera, you do not need it, you may zoom the same way using appropriate software and in contrast to optical zoom you always loose quality using electronic zoom :-))).
Top secret: my camera has 7 x optical zoom. WOW ---> I am not forced to walk too much hehe.
Look at my picture? Do you like it? Hehe.
Be careful! San Diego offers a lot of sun (even in April when I visited it) so taking pics of architecture maybe difficult especially in a midday.
Read/learn about black & white balance (if your camera has manual B&W balance regulation) or wait for better light or walk (don't be lazy, it's healthy :-) and take a picture from the other side.
Ok, OK, OK.
Hmmm... sometimes it was not so easy to take pictures, especially of the old cars which were presented (and sold) at Gaslamp District. Although... look at the nest tip.
