This is probably a very stupid question....but I am wanting to convert some color photos to b&w. On Arcsoft Photo, I have the option to convert to Grayscale. Is this the exact same thing as black and white? Please forgive, me...I am just learning how to mess with the photos.

I'm not familiar with Arcsoft; however, if there is a way to adjust hue/saturation, try that instead of grayscale.

Converting an RGB image to Grayscale is the exact same thing as converting it to black and white.

A grayscale image is essentially the colour image with the colour information simply discarded, using up to 255 shades of gray (8 bit image) in it's place.

The resultant grayscale (black & white) image tends to be a little flat though, certainly with Photoshop. I don't know Arcsoft, so it may be different, though I doubt it.

This is why users generally employ a different approach to converting. Again, in Photoshop there are numerous ways to convert, that each give far better results than simply switching to grayscale mode. You should explore your software for alternative methods.

If it has a hue/saturation function as Lucky said, try that.

In the meantime you could try increasing the contrast and brightness of the image before you convert. Don't worry if the colour image looks a bit 'too much', once the colour has been discarded you should be left with a more pleasing grayscale, in terms of less flatness/more contrast. Though I do prefer very contrasty black and whites, you may not.

The best thing to do however, is to try different things, move any sliders around, play with it until you see something you like.

If it works for you, then that's what is important !!
