Technically, the tap-and-lift photo feature is part of Visual Look Up, which was first launched with iOS 15 and can recognize objects in your photos such as plants, food, landmarks and even pets. In iOS 16, Visual Look Up lets you lift that object out of a photo or PDF by doing nothing more than tapping and holding.

During the WWDC, Apple showed someone tapping and holding on the dog in a photo to lift it from the background and share in a Message.

Apple

Robby Walker, Apple senior director of Siri Language and Technologies, first demonstrated the new tap-and-lift tool during WWDC. He had a photo of a French bulldog and tapped and held on the dog. Walker dragged the dog's "cut out" from the photo and into the text field of a text message.

"It feels like magic," Walker said.

Sometimes Apple overuses the word "magic," but this tool does seem impressive. Walker was quick to point out that the effect was the result of an advanced machine-learning model, which is accelerated by core machine learning and Apple's neural engine to perform 40 billion operations in a second.

Knowing the amount of processing and machine learning required to cut a dog out of a photo thrills me to no end. Many times new phone features need to be revolutionary or solve a serious problem. I guess you could say that the tap-and-hold tool solves the problem of removing a photo's background, which to at least some could be a serious matter.

I couldn't help notice the similarity to another photo feature in iOS 16. On the lock screen, the photo editor separates the foreground subject from the background of your wallpaper's photo. This makes it so lock screen elements like the time and date can be layered behind the subject of your wallpaper but in front of the photo's background. It give the lock screen a slick magazine cover ovibe.

I've used the new Visual Look Up feature many times now and I'm still impressed how quickly and reliably it works.

1. Ensure Your iPhone Is Updated To iOS 13

The built-in Photos app is one of the best photo editing apps for iPhone.

And with iOS 13 (iOS is the iPhone operating system), you get a completely redesigned photo editor.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The new Photos app has a wider range of editing tools. And you can fine‑tune your edits with more precision than before. You can even edit videos using the same tools that you use to edit photos.

To ensure you have these new iPhone photo editor tools, make sure your iPhone is running the latest iOS 13.

To update your iPhone to iOS 13, open the Settings app from the Home screen. Then go to General > Software Update.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

If your software is up to date with iOS 13, you’ll already have access to the new photo editing tools.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

If your software isn’t up to date, follow the on-screen instructions to download and install the latest iOS 13. (Before doing this, it’s a good idea to back up the data on your iPhone – just in case something goes wrong during the update process!)

Note that if you have the iPhone 6 or earlier, you won’t be able to update to iOS 13. And therefore, you won’t have access to the new editing tools in the Photos app. You can still use the old editing tools though – you just won’t have as many tools to work with.

2. Duplicate Your Photo To Preserve The Original (Optional)

When you edit a photo in the Photos app, the original image gets replaced by the edited version.

However, editing in the Photos app is non-destructive. This means you can undo edits or revert back to the original image at any time.

But sometimes you might want to keep the original photo, along with a separate edited version. If so, you can easily duplicate the image before editing.

To duplicate an image, open it in the Photos app and tap the Share icon at the bottom left. Then scroll down and tap Duplicate

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Tap the Back arrow at the top left to return to your photo library.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The duplicate image will appear at the bottom of your photo library. You can edit this image while the original remains unedited.

Read on to learn how to edit photos on iPhone using the built-in photo editor tools.

3. Open The iPhone Photo Editor In The Photos App

So, how do you open the photo editing tools in the iPhone Photos app?

Just open the photo you want to edit, then tap Edit at the top right of the screen.

How to add a photo to another photo iphone

In the iPhone photo editor, there are three icons at the bottom of the screen. Or if you’re editing a Live Photo, there will be four icons.

And the best place to start is by making a few quick adjustments to color, brightness, and sharpness.

To make adjustments to your photo, ensure the Adjust icon (dial) is selected at the bottom of the screen.

How to add a photo to another photo iphone

Beneath your photo, you’ll see a row of adjustment tools. Swipe across to see more tools.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

4.1 Auto Enhance

The Auto tool automatically adjusts the colors and brightness levels in your photo.

Simply tap the Auto icon to apply this one-tap edit. The icon turns pale gray when it’s switched on.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The great thing about the Auto tool is that you can actually fine-tune the edits that it’s made.

You can use the slider at the bottom of the screen to adjust the strength of the edit.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

You can also adjust the individual edits that have been made to color, brightness, etc. If you swipe across the adjustment icons, a bold line indicates which tools the Auto adjustment has used.

How to add a photo to another photo iphone

To fine-tune an individual adjustment, tap on the tool and use the slider to adjust its strength.

If you want to remove the Auto edit from your photo, tap the Auto icon so it turns dark gray.

How to add a photo to another photo iphone

Now, you’ll discover how to use the manual adjustment tools to make your own edits.

4.2 Exposure

The Exposure tool brightens or darkens your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to brighten the image, or left to darken it.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The Exposure tool has more effect on the highlights than the shadows. This means that the bright tones in your photo are affected more than the dark tones.

4.3 Brilliance

The Brilliance tool is great for bringing out details and making your photo look richer and more vibrant.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to brighten shadows and darken highlights. If you drag left, the shadows will become darker and the highlights brighter.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

4.4 Highlights

The Highlights tool adjusts the brightness of only the bright areas in your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider left to make the highlights darker, or right to make the highlights brighter.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

4.5 Shadows

The Shadows tool adjusts the brightness of only the dark areas in your photo.

How to add a photo to another photo iphone

Drag the slider right to make the shadows brighter, or left to make them darker.

How to add a photo to another photo iphone

4.6 Contrast

The Contrast tool adjusts the contrast between the dark and bright tones in your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to increase contrast, making the shadows darker and the highlights brighter. Or drag left to reduce contrast, making the shadows and highlights more similar in tone.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

In most cases, reducing contrast doesn’t produce good results. Increasing the contrast a little can make your photo look sharper. However, you’ll often get better results with the Brilliance tool as it keeps the colors nice and vibrant.

4.7 Brightness

The Brightness tool brightens or darkens your photo. But it does it in a slightly different (and usually better) way from the Exposure tool.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider left to darken your photo, or right to brighten it.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The Brightness tool has more effect on the shadows and midtones. This means the dark and medium tones get adjusted more than the bright tones.

4.8 Black Point

The Black Point tool affects the brightness of only the darkest tones in your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

If your photo lacks rich black tones, drag the slider to the right to make the darkest areas appear black. Dragging to the left will make the dark areas appear faded.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

4.9 Saturation

The Saturation tool makes the colors more vibrant or less vibrant.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to make the colors more vibrant, or left to make the colors more muted.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

In most cases, increasing the saturation a little bit will make your image “pop.” But be careful not to over-saturate the colors. If you make the colors too vibrant, they won’t look natural.

To create a black and white photo, set the Saturation to -100.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

4.10 Vibrance

The Vibrance tool makes muted colors more vibrant without affecting skin tones or saturated colors too much.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to boost the vibrancy of muted colors. Or drag it left to reduce the vibrancy.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The Vibrance tool usually produces more natural-looking colors than the Saturation tool. This is because it doesn’t over-saturate skin tones or colors that are already vibrant.

4.11 Warmth

The Warmth tool makes the colors in your photo warmer or cooler.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to make the colors warmer (more orange). Or drag it left to make them cooler (more blue).

How to add a photo to another photo iphone
How to add a photo to another photo iphone

You can use the Warmth tool to correct the color balance of a photo. Or use it to change the overall mood of an image.

4.12 Tint

The Tint tool allows you to add a green or magenta color tint to your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider left to add a green tint, or right to add a magenta tint.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

The green tint is great for increasing the vibrancy of green leaves or fields. Just be aware that it tints the entire photo, so all colors will be affected.

4.13 Sharpness

The Sharpness tool sharpens detail in your photo by making edges crisper and more defined.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to make the image sharper.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Be careful not to increase sharpness too much. Over-sharpening will reduce the image quality.

4.14 Definition

The Definition tool adjusts contrast to improve the clarity of detail in your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to increase clarity and definition in your image.

How to add a photo to another photo iphone

4.15 Noise Reduction

The Noise Reduction tool reduces “digital noise” – such as grain caused by shooting in low light. You can also get grain in your photos when editing, e.g., if you brighten the shadows too much.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

If you have a grainy or “noisy” photo, drag the slider right to reduce the noise.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Use this tool sparingly as too much noise reduction will soften the detail in your photo.

4.16 Vignette

The Vignette tool darkens or brightens the edges of your photo.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

Drag the slider right to add a dark vignette, or left to add a bright vignette. A dark vignette usually looks better than a bright one.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

A dark vignette can help draw attention to the center of the image. It’s also great for adding a sense of drama to your photos.

5. Use A Filter To Adjust The Color Tone

Filters offer a quick and easy way to change the look and feel of your photo.

With a single tap, you can adjust the color tone of your image using a range of color and black and white filters.

6.1 Auto Crop & Straighten

When you first open the Crop options, you might notice that your image is automatically straightened and/or cropped.

To adjust the vertical perspective, tap the Vertical Perspective tool beneath the image. Drag the slider to adjust the vertical perspective.

How to add a photo to another photo iphone

This tool is great for architecture photography. If you took a photo of a building from a low angle, the building may appear to converge towards the top. Adjusting the vertical perspective allows you to straighten up the vertical lines on the building.

To adjust horizontal perspective, use the Horizontal Perspective tool.

6.5 Crop

The Crop tool lets you remove the edges of your image.

Cropping your photo is great for getting rid of distracting elements from the edges of the frame. This results in a cleaner, simpler image with a stronger visual impact.

How to add a photo to another photo iphone
How to add a photo to another photo iphone

You may also wish to crop your image to improve its composition. For example, cropping can help you create better symmetry or apply the rule of thirds after taking your photo.

How to add a photo to another photo iphone

Cropping also allows you to zoom in on a distant subject. But be careful not to crop too much of the photo as this can result in a small, low-quality image.

To crop your photo, drag the corner crop handles. A white border indicates where the new edges of the photo will be.

If you crop in too far, drag the corner crop handles out again. Or pinch inwards with two fingers to bring more of the image back into the frame.

13. Limitations Of The iPhone Photos App

The editing tools in the Photos app are perfect for everyday image editing. But it does have some limitations.

It’s missing certain features that you’ll find in some other popular photo editor and photoshop apps.

In particular, it doesn’t include the option to make selective adjustments to a certain part of an image. And it doesn’t have a healing tool for removing objects from your photos.

If you’re looking for a more advanced photo editing app with these tools, the free Snapseed app is a great option.
