As it's B&W film also consider coloured filters which could buy you a stop or two. These may also be useful to change the tonal relationship between colours (e.g. a tomato on a lettuce leaf shot through red filter will appear light on dark and through green filter will appear dark on light (forgive me if this is teaching Grandma to suck eggs!)).Originally Posted by clogz
If you use any filter then be wary of flare, especially in the bright light conditions that you describe.
All the best,
