One of the most important characteristics of photography is the lighting, hence if there is too much lighting then definitely your shot gets overexposed or worse, you do not get a shot at all. If there is little or no lighting then your photo also suffers because you either lose your photo all together or it comes out underexposed. Most of the time when it comes to photography lighting, natural light is all one needs. In most occasions you will find most people waiting for sunrise and sunset to take magnificent photos.
You will also find that photography lighting is also important when it comes to cloudy days or days when it is raining many people have no interest in taking photos. However there are a few people who do not mind taking photos on this kind of days and some even take photos of lightening which could be extremely dangerous if you are not clever.
It is best that you take photography lighting seriously especially if you do not want to keep overexposing your photos to too much sunlight. Most photographers switch to flash lights if it gets dark and want to take more photos, this usually depends on where you are and how dark it maybe. If you go to photo studios even during the day you will find that the camera man might switch on the studio photography light or will switch to a camera flash, or to an off-camera flash. Photography is mainly about instinct, if you have it, believe me you will enjoy greatly taking your photos.
