I am not at all an expert in photography. I admire the work of those who perform it, like yours. But as a simple spectator. I think the best photo is the one that speaks for itself. You do not need any fancy filter. There are photos that they make you feel things. Your photo of the cart of recycled materials, is that kind of photos. That photo speak .

I think being simple is a way of living. When one learns to enjoy the simplicity of things, one lives better. And if you live simple, your photos can do wonders valuing the simplicity of day to day.

cheers my friend! Greetings from Argentina.
