Professional flashes should have a slide up card that will throw the light forward while bouncing of the ceiling. Slide in and out no hassle. Same outside I never use straight on flash unless your very experienced or have a lot of time you will see hot spots and changes in clothing color tones on group shots. I angle the flash just over the heads of the subject using the card to bounce down for the eyes. Meter for the ambient and add fill flash, compensate down so it looks like there was no flash used. If you don't have a high end flash you can make a better bounce card which folds up and down easy and fast and throws more light forward or Al's business card method. www.abetterbouncecard.com YOUR QUOTE: "Ambient light is aquired by lowering the shutter speed and flash for the subject" It can can also be aquired by opening up the aperture.
