As a commercial photographer, you would always need lots of practice and experience to keep learning the art and the nuances of photography.
If you are a budding commercial photographer, an amateur, a dabbler you would need a lot of training to know the skill and get better at it, in order to be successful.
Or even if you have years of experience and have got the due recognition and the love of clients, you still need lots and lots of practice and research to keep yourself updated and never rust.
But practising your art with a film camera is and has never been a very feasible idea.
The only reason why film cameras have never been a very good option for practice is the cost that it entails.
The running costs of a film camera is quite high.
First it requires film rolls, which are expensive and they are an absolute requirement for such cameras.
Second, if you take a shot that you don't find good enough later on, it would mean that you have wasted your film roll there and whether or not you choose to print it, the image has captured its space in the film roll.
Therefore film cameras have never been a very good option for a commercial photographer, especially those who face a frequent shortage of money.
And for commercial photographer of today, digital camera has come like a boon in disguise.
Though these cameras are a little expensive as compared to the film cameras, but the running costs are quite low.
You just need a memory card where you store the shots you take.
From the camera, with the help of a USB cable, you can transfer your pictures to the computer and then delete all the pictures from the memory card.
Then you can use the free space for more pictures.
