Camera Flash



Paparazzi

Why does everyone insist on using the flash constantly? 
 
Although it might be a slightly dull topic to begin my blog with, it's actually something that I feel is rather important because there is a lot of controversy over who is 'right' or 'wrong' about the situation when it comes to flash.

Firstly, what is a flash? I hear you ask. Flash photography is used to create an artificial light to help illuminate a scene, particularly a dark one. It can also be used to capture objects that are moving quickly or it can also just alter the quality of the light.

You will commonly see flashes built into compact cameras already which will automatically be triggered by the shutter. This is even seen on a DSLR when using automatic mode. This tells the camera operator that flash must always be needed. However, the camera is assuming that the inexperienced photographer on auto mode won't be aware if they have a good quality of light or not and therefore just alters the light for them anyway with an automatic flash. This is obvious as in a manual mode, the flash will not be triggered unless you tell it to (given that you previously assess the lighting condition ahead of you). This proves that an automatically rising flash is due to the assumption of inexperienced users not being able to tell what needs to be used.

When using a DSLR, other than using the 'on- camera' flash, you can mount a flash to the accessory mount bracket or 'hot-shoe'. The problem with this is that if you don't know how to use it properly, you will use the flash just as a 'direct' light source, much like the built in flash but with a higher light intensity meaning that the image will be quite still and unmoving. I would definitely recommend a bounce flash if possible (when you're inside with a low enough ceiling) as the light created is much softer and even. This effect can also be created with the use of a 'Fong' and possibly a dome. This is just a diffuser which the light of the flash hits and therefore spreads the light out more evenly. I don't particularly like this type of diffusion as it looks quite unprofessional with a big plastic cup attached to your flash.

You always see the paparazzi on the TV photographing celebrities with their huge DSLR cameras and hige flashes attached to them. However, you also see them holding the camera up above the crowd and just pointing downwards. This involves no skill what so ever as they don't even look through the viewfinder to see what is in their shot before they press down on the shutter. This must also be bad for photographers surrounding them as numerous flashes going off at once would surely disrupt a few lighting conditions.

In addition to this, the cost of a flash to attach to your DSLR would roughly set you back about £150-£200 whereas it would be free to use natural lighting. Also, the size and weight of the flash has to be considered when you carry around all of your gear.

Ring Flash

Positives for flash:

  • Ring flash creates a lovely 'halo' effect
  • Good if there is not much available light
  • Studio flash lighting is needed to illuminate the model in the darkness

Natural lighting just cannot be beaten at all. If you compare an image taken with a flash to one taken using natural lighting, you will see how soft and even the lighting can be when it's natural. My favourite example of this is Julian Germain and his project 'For every minute you are angry, you lose sixty seconds of happiness'.


Next time you go to take a portrait shot, instead of using the flash, just stand your model by the window instead with the light coming in towards one side (if the window is behind them then you'll get a silhouette) and you will see how effective it can be for a naturally occurring element.
