and if anyone could help me out...i have a hard time photographing my work.. is there any tips or tricks .. i cant seem to capture how it looks in real life and its really frustersting

david, first of all, and most importantly, find a good location that has a bright window.

second, diffuse the light somewhat. could be as simple as pulling down a translucent white shade.

this will provide a soft, even light for your subject. unless you shoot at the "golden hours" of sunrise or sunset you'll have nice white 5500k light.

longer lenses can help decrease the barrel distortion, but you may run out of room.

on zooms there is an optimal focal length that tends to minimize barrel/pincushion distortion. on this tammy the change from barrel (on the wide end) and pincushion (on the long end) seems to be around 24mm. you can compensate with your post processing using some specialized software, but as usual it's better to get it "square" right away.

also zoom lenses will show different vignetting wrt focal length. usually it gets better as you go longer. around 35mm the tammy gets very good in that respect. you can compensate with your post processing but again it's better to have it right from the camera (as pushing up exposure in post invariably makes noise worse).

so, using this lens, a good focal length would be between 24 and 35mm.

shoot at the optimal aperture for sharpness. i believe it was established earlier in this thread that f/5.6 or so on this tammy is the sweet spot for sharpness.

obviously use the lowest ISO you can.

shutter only needs to be as quick as eliminating shake. consider a tripod, though given a nice bright day with plenty of light, a quick shutter is guaranteed anyway.

finally, make sure your lens axis is directly orthagonal to the object frame plane to avoid keystoning.

ckfishel2001, it seems to me like you've focused on the door...at least it's sharper than two girls in front of it.

LOL thanks alot , yeah they are mine and are pencil drawings , just a hobbie of mine:D

Amazing! Do you use photographs or are these purely out of your imagination?

Otherwise, what kind of advice would you give to someone wanting to draw these kind of realistic drawings?
