Butter your dragon.....

Post by Dearis »

Hi there,

these techically are not macro shots, I used my 70-200mm f/4 L yesterday. The butterfly I was pleased with however the dragonfly I was not but I posted it because I would love some input on how on can improve or take better dragonfly and damselflys.

C and C most welcome as always.

Regards Darren

Darren, for the dragonfly you used 200 mm, 1/80 sec, f/8 and iso 100.

If you did not use a monopod or tripod, I bet you shaked the camera too much for that combination of focal lenght (200 mm) and shutter speed (1/80 sec). Normally a rule of thumb would say that 200 mm requires 1/200 sec shutter speed, or better even shorter like 1/300 sec.

You should use higher iso than iso 100, as that will give you faster shutter speed with the same aperture f/8. Had you used iso 400, you would have had 2*2 = 4 times shorter exposure, that is 1/320 sec.

I normally photograph dragonflies without flash light, and I rarely use anything below iso 400. Normally I set camera to iso 400, and then adjust upwards to 800 or more if needed. But I use a monopod, and mostly get sharp pictures at 1/100 sec at 210 mm.

Your 350D should yeild good pictures at iso 400, but also acceptable noise at iso 800.

I think the dragonfly is a bit overexposed too. The dark background fools the camera's light meter (if M, manual mode, is not used). With a background like this, I would probably try out with -1 EV exposure compensation, have a look at the image on the camera screen, and adjust maybe to -1,33 EV, if the dragonfly still seems too brigth. Had you used exposure compensation, you would automatically get a faster shutter speed, and avoid getting a shaken picture.

forgot to ask, what program on the camera are you using ? Most people probably use the AV mode, setting an iso value before getting started, and then adjusting aperture to get an ok shutter speed, at the given situation.
