For example, while the Mac version of iPhoto would have fairly rigid settings for things like vignettes, it is now possible to move and resize your vignette by simply pinching your fingers on the screen. You can also alter the colours of your shots by swiping on the screen rather than having to drag endless sliders around. Here we focus on Black & White. This is no longer an effect that looks the same every time thanks to the slider at the bottom of the screen, and you can create some incredible-looking vintage shots, all of which are totally different, using just this one tool.
Step 1: Choose your photo
Find a photo to edit using the browsing options like Albums and Events. You can see all the images in the chosen section to the left; just tap the one you want.
Step 2: Enter Editing mode
Next, open up the Editing menu. Tap the button in the top-right and a bar will appear with options such as auto-enhance and rotate in the middle.
Step 3: Pick the effect
In the bottom-left, hit the Effects button. A swatch book will open with a host of filter types, so choose the Black & White swatch from this menu.
Step 4: On the bar
The bar at the bottom represents different tones. Slide your finger along the bar to set the lightness of certain areas of the photo until you find your perfect level.
Step 5: In the frame
Next to the bar are three buttons. The leftmost adds a vignette. Tap it and place two digits on the photo; pinch and move your fingers and the frame will move.
