raspistill very slow (normal?) - Raspberry Pi Forums

i'm using rpi b 2meg pixel camera board.

command i'm using (via ssh cli connection)

raspistill -w 960 -h 720 -n -o filename (also tried adding -gc)

takes 9 seconds create image file.

if add in -t 5 - cuts 4-5 seconds - image dark.

matter of lighting determine how long takes raspistill return camera image?

there other faster cli utilities pulling camera image?

thanks

it takes few frames exposure time, gain, , white balance determined. if had monitor attached see running preview first few seconds.
default -t 5000 5 seconds delay, can safely go down 2000 without issue, , down 1000 if add -st make run additional processing on actual capture frame optimise awb.
if use -ss , -iso set shutter speed , gain can drop -t further need determine correct shutter speed , gain scene (you'll still want -st there ensure awb chance run, or can use -awb=off -awbg=<red_gain>,<blue_gain> manually set too.
