How is the weather there in Kerry on this Mothers day!
Its a nice scene, and always a good idea to try b&w.
I agree with Keith, - start with a colour image. The use this to convert to mono, using any editing programme. You will have a lot more control over the final product. There are also special programmes that can convert colour to mono automatically, or with lots of control, - your choice.
If you scroll down to the bottom of this page, bottom left, theres a strip that goes from white to black in 16 steps; a good mono or b&w image will contain a range of these topnes, from black through to white, or very close.
The image has tones that are in the middle of that range as mentioned, - a range of greys, or mid-tones.
But its a start, and you have to start someplace.
lets know what software programme you use and we can give you more specific advise.
Mu version of this is different than Keiths, - so you have a lot of options.
In general, when you take a shot that contains the sky, the lower part will be underexposed. So I have brightened the lower area, made the darkest spots = black, and sharpened quite a bit. Its cropped a little to get the horizon on a third. The horizon is straightened, very slightly off, and Ive corrected the barrel distortion that makes the horizon curve upwards.
Take a look, and see what you think. Try converting some of your existing colour shots to mono for practice.
