1 3 and 5 are the best ones. However. I don't think you need to have them all be black and white. But you probably took the pictures in black white, right?
No, but my intention was to make them black and white later, though the colour ones are good, I decided just to stick with the plan for ease.
Taking photos in black and white (on a digital camera) is a stupid idea. Take them in colour and desaturate them on a computer where you have more control.
The only reason to have black and white photographs straight out of a camera is if you've genuinely used black and white film.
Yes, I did that. Although desaturation isn't the best option to make it black and white.
