Photographing the concert begins long before it starts. It is optimal to scout the shooting location in advance so that you know all its advantages and disadvantages in advance. Among other things, it is important to prepare a strong professional photographic equipment.
Intelligence service. Determine the location of the stage, auditorium and your own. Provide yourself with the ability to move around the room. If possible, arrange for yourself to go on stage to take a closer look at the artists.
Technique. Lenses should have the highest aperture ratio. The flash during the time is useless at best, and at worst you will not be able to use it - it is not recommended to blind the performers in the eyes during the performance, so as not to knock and distract them. Also, take care of the ability to quickly change focus.
Shoot in manual mode only. Automation will compensate for dimly lit elements of the composition. Use spot metering to individually capture the participants in the performance.
Look for footage not only on stage. Pay attention to specific spots of light, audience reactions. Actively use hover to zoom in on individual objects and backward hover for panoramic shots and general shots.
