GRIM architecture in Black/White and Sepia

Not all of it is grim, and not all of it is black and white:

1.

2.

3.

4.

5.

6.

 

I like 2 and 3 the best. Good patterns and pretty good contrast.

 

Thanks. These are some of the first B&W conversions I have done. Something I found impossible was capturing the full dynamic ranges, so the skies are blown out! They would have looked much better with a nice sky but to be fair, it was white and cloudless. Any more tips?
