got a question, shooting Portraits photo. Sometime got 3 model how can i make 3 model sharp.
Pose them in such a way that they are standing in parallel, so that they have roughly the same distance from your camera. Focus on their eye level, and have a decent shutter speed to avoid camera shake (or have a very steady hands!). Pretty much like it. Worst case scenario you have to rely on manual focus if the lighting condition or the background is too distracting for the camera to calculate a very accurate focus.

is that still can get bokeh background?
Pull your lens to the longest zoom available. Then stand as close to your subject as possible, until your composition is right (either you want tight framing or wider shot). That is one "cheating" way to get bokeh, rather than having lens with larger apertures.

But then still works. People will think you have a bigass expensive lens.

But with this trick, the further away the background from the subject, the better
Of course, if you want even better bokeh, you still need to get lens with larger apertures, like f/2.8 or bigger to have even more blur.
