Shoot Film - beauty of film is it forces you to slow down and think. This is very important to help you visualize what you want to capture in the given scene in front of you. Shoot JPEG - don't have film? Shoot JPEG. Set your JPEG recipe once and don't touch it again.
Leave your camera at home - take a journal with you and write down what you see. Try to get as much detail as you can with 5 minutes. When you're 5 minutes are up describe what you see next.
Get off the computer and do something else creative - ...wait!! First share this article with your friends and leave a cool comment. Seriously though if you shoot a lot like I do sometimes a fresh creative outlet will help you to break through a rut.
Photograph a subject you don't normally capture - When I want to grow I'll shoot landscapes, nature or still life photographs. It's not my speciality but shooting something that you normally don't can help you become better at your speciality.
What do you do to get back that loving feeling when its gone? Let me know in the comments.[hr]
Bonus! Cover up your LCD screen. Don't have an EVF? Go ninja! Just close your eyes and "feel the photo" :roll: Why not? Nikon made pros do it back in the day with their D1 cameras.
Note - We really do love Nikon but we could not resist.
