The chemical and digital technology are vying with each other for facilitating more the cause of cameras and photography, but in the present scenario it seems that digital technology has the upper hand and has established itself as the reigning king of the market. Digital cameras are cheaper in the long run for your photography passion and these digital images can be easily stores in multiple places and can be manipulated. But there is one more impact that these digital cameras have made in improving the environment, for, the use of chemicals and other intoxicants in the film cameras is reduced. This sounds very confusing and almost everybody seems to ignore this effect in the glittering aura of other features that these digital cameras provide.
Nobody seems to be aware of the fact that when we take these films to the developing center, these films undergo many processes with certain chemical, which are actually hazardous to our environment. It should be noted that after using these developing and fixing solutions, they are thrown out in the environment and this, in turn, pollutes the environment to a great extent.
It is not that there are no laws for disposing these environment hazardous chemicals; certainly there are some, but due to the expense that these laws and the processes therein incur, developing companies just avoid following those laws. Chemicals must be stored in absorbent materials and then dump in wasteland after these have been rendered inert. No question that bigger and established companies adhere to these laws, but this is the case with small scale and new companies: they just put the waste chemicals in drain, which is very dangerous for domestic life.
There is one more way to dispose off these chemicals, and this is done by cruises, which are not bound by the US environment standard laws. These ships throw the chemicals of photo-developing companies in the sea and thus cause a major problem for the aquatic life. These things are avoided with the use of digital cameras, for, there is no chemical involved in these digital cameras.
However, these digital cameras are not totally out of questioning from danger forum, as they use the ink for printing the photographs. The human skin sucks this ink, if someone handles it when it is not dry. But there is certainly no problem after the ink is dry and there is no danger handling it.
Another thing that can be raised against these digital cameras is the use of batteries, for they certainly are hazardous to our environment. But almost all the digital cameras come with rechargeable batteries, and therefore, the threat is lost from these batteries.
It is clear from the above discussion that digital cameras are better from many angles, and they pose less threat to our environment than the film cameras. And it goes without saying that other features of these cameras have already outsmarted the film cameras, and they are going to rule the market for long.
