iPhoneでポートレート照明を調整する方法

You can adjust Portrait Lighting on your iPhone both before and after taking a photo. 1. Before taking a photo, open the Camera app, select Portrait mode, frame your subject, tap the lighting effect name, swipe through options like Natural Light, Studio Light, Contour Light, Stage Light, Stage Light Mono, or High-Key Light Mono, choose the desired effect with real-time preview, then take the photo. 2. After taking a photo, open it in the Photos app, tap Edit, scroll to Lighting, tap the current effect, select a different one, and tap Done to save. Note: Effects require proper lighting and distance; some are unavailable in low light or incorrect range. Portrait Lighting only works with Portrait mode photos, not non-Portrait selfies, and older iPhones may have fewer options. Preserving depth data allows switching effects without quality loss if the photo isn’t cropped or flattened. This feature enhances portraits with professional lighting effects either pre- or post-capture.

You can adjust Portrait Lighting on your iPhone both before and after taking a photo. This feature simulates professional lighting effects to enhance the look of your subject’s face in Portrait mode. Here’s how to use and tweak it:

Before Taking a Photo (Live Adjustment)

When you’re in the Camera app and have selected Portrait mode:

1. Open the Camera app and tap Portrait at the bottom.
2. Frame your subject — the iPhone will automatically detect if the lighting and distance are suitable.
3. Once the lighting effect name appears (like “Natural Light”), tap it to open the lighting options.
4. Swipe through the available lighting effects:
   • Natural Light – subtle, balanced lighting
   • Studio Light – evens out skin tones and adds soft front lighting
   • Contour Light – adds dramatic shadows for a sculpted look
   • Stage Light – darkens the background and highlights the subject
   • Stage Light Mono – black-and-white version of Stage Light
   • High-Key Light Mono – bright, airy background with a B&W subject
5. Select the desired effect. You’ll see a preview in real time.
6. Take the photo.

Note: Some effects (like Stage Light and High-Key Light Mono) require good lighting and distance to activate. If they’re grayed out, adjust your environment or move slightly back.

After Taking a Photo (Edit Later)

You can change the lighting effect anytime after taking the photo:

1. Open the Photos app and go to the portrait photo you took.
2. Tap Edit in the top right.
3. Scroll through the editing options at the bottom until you see Lighting.
4. Tap the current lighting effect (e.g., “Natural Light”) to open the menu.
5. Choose a different lighting style from the list.
6. Tap Done to save your changes.

Tip: The original depth data is preserved, so you can switch between effects without quality loss — as long as you don’t crop or alter the photo in a way that flattens the image.

A Few Things to Keep in Mind

• Portrait Lighting works only with photos taken in Portrait mode.
• Lighting effects are not available for selfies taken in non-Portrait mode.
• Older iPhone models may have fewer lighting options.
• For best results, ensure your subject is well-lit and within the recommended distance (about 8 inches to 6 feet from the camera).

Basically, adjusting Portrait Lighting is a quick way to give your portraits a professional touch — whether you decide on the look before or after the shot.
