A very popular enhancement, especially for wedding photos, is to spot color elements of the photo. The bouquet is always a favorite but there are many other applications as well. How this is done: select the area of a color image you'd like to retain as colored. Copy the selected area and paste into a new blank file (Photoshop: hit FILE, NEW, BLANK FILE, PASTE). Now under IMAGE, MODE, grayscale the original image to make it b&w. After that, make the image RGB again. It will remain b&w but will now accept color elements. Copy and paste your selected bouquet (very precisely) on top of the b&w bouquet. It makes a charming and very popular photo.
