The idea that 'practise makes perfect' has been drilled into me from a young age. While I don't believe you should wait for perfection (nothing is perfect and so you will wait forever) I do firmly believe perfection should be something we strive for. We will always miss but the closer we get the better our creations will be and the more consistently we will be able to create.
Practise has the real risk of becoming being dull, however. When we repeat a task over and over again it can take something you love and push it firmly into the mundane and risks killing creativity. I have first-hand knowledge of this with product photography. A field where repetition and consistency are key for image creation but remove nearly all forms of creativity from the act of creating.
So the balance must be made between repetition and gripping boredom. If only my school teacher had figured that out. Without this balance, you will burnout.

Variations along a theme, this was shot on film and then processed by me!

This is nice and all, but why are you talking about this?
At the time of writing this, I have been shooting with a model ( Instagram:- @kirstyspence ) for a while and we have been doing the same style of shoot. While not a bad experience it is important for us to stay creative and we are getting better at this style of shoot. Continuing to shoot like this wouldn't be a bad thing but it is going to be difficult to keep creating interesting images by repeating ourselves.

So its time for something new?
Yes and no. We will probably come back to a shoot like this when we have another idea that warrants it but for now, we are looking to shoot in a different setting and create differently styled images. This was it keeps things fresh and what we create will be of more use to us in the future. It also allows us to explore new ideas and maybe hone what we really want to continue doing. Ultimately, exploration is so important in any form of practice.
