One-Hour Photo: Film Camera Filter

Quick answer: Choose one photo or up to 30, pick a look and tap Save. Point & Shoot is an everyday snapshot, Disposable is a ’90s flash camera, Film Roll is a 35 mm print and Black & White is what it says. Each one is what a simple camera does to a picture: a little grain or noise, softer corners, a gentler tone curve and real-world colour. Every photo is saved as a fresh JPEG with none of its hidden details, and with a name. Nothing is uploaded: it all happens in your browser.

How to use it

1. Choose your photos. One, or a batch of up to 30. On a phone this opens your photo library. They stay on your device.
2. Pick a look. Each button shows your own first photo in that look. Move the Strength slider to taste. Press and hold the picture, or the Before button, to see the original.
3. Name them, or don’t. Type a name and one photo saves as that name, a batch as name_1, name_2 and so on. Leave it empty and each photo gets a name of its own (see below).
4. Tap Save. One photo downloads as a JPEG. A batch downloads as one .zip. On a phone you can also send the whole batch to Photos in one tap.

The five looks

• Point & Shoot (the default): a compact digital camera, the “digicam” of the 2000s that the Y2K look copies. A slightly punchier tone curve, a touch of warmth, corners a little softer and darker, and noise that is strongest in the shadows, with the faint blotches of colour a small sensor leaves there.
• Disposable: a 1990s throwaway camera with its flash. Warm colour, a greenish tint in the shadows, blacks that never quite reach black, stronger falloff toward the corners, a warm glow round bright lights and coarse film grain.
• Film Roll: a 35 mm colour print. Soft contrast, lifted blacks, a gentle roll-off in the highlights, warm highlights and cooler shadows, the faint red glow film gets round bright highlights, and grain sized to the frame.
• Black & White: a black-and-white film, mixed a little toward red so skin looks natural, with grain and rich blacks.
• Clean only: no look at all. The picture is kept exactly, byte for byte when it is a JPEG, and only its hidden details are removed and the file renamed.

A look is the same for every photo in a batch, like one roll of film, so the photos look like they belong together on a board.

What a simple camera does to a picture

A photo from a phone app or an image program, and most of all one an AI made, is often too perfect: edge-to-edge sharp, no grain, rich colour even in the deepest shadows, skin as smooth as plastic and highlights with clean edges. A simple camera shows itself in seven ways you can see, and each look is a recipe of them:

1. Noise or grain. A digital sensor adds fine noise, most in the shadows. Film has grain, most in the mid-tones, in soft clumps, with a little colour in it, since each colour layer has its own. Here the grain is sized to the picture, so it still shows when Pinterest makes your photo smaller.
2. A tone curve. The darkest shadows settle and the brightest parts roll off gently instead of clipping. The photo’s overall brightness stays about where it was.
3. Real colour. The most saturated colours are pulled in a little, because a small camera cannot hold neon, and the deepest shadows hold less colour. Skin tones are left alone.
4. The lens. Corners a little softer and a little darker, and a hair of colour fringing at the edges, in proportion to the picture.
5. Glow. Light spreads a little from the brightest parts into what is around them: a red halo on film (halation), a soft flare through a cheap lens. The light is moved, not added, so the photo is no brighter.
6. In-camera sharpening. A light sharpening in the middle of the frame, done before the grain so the grain stays soft.
7. A camera’s JPEG. Saved at quality 92, in sRGB, the colours every screen expects.

Strength 0 leaves the picture untouched. A look changes how a picture looks, not what is in it.

What the clean-up removes

A photo file carries hidden details next to the picture. A phone writes where you were (GPS), the date and time, the phone or camera model and often its serial number. Editing programs add their name and an editing history. Anyone you send the file to can read them. Every photo saved here has none of them: a look is drawn into a brand-new JPEG, so nothing from the original file is copied across. Clean only removes every block of hidden details from the original JPEG and keeps two things the picture needs: its colour profile, so the colours stay right, and which way up it goes. A PNG, WebP or HEIC photo in Clean only is saved as a JPEG at quality 95.

Phone photos taken sideways are turned upright in the pixels first, so they never save on their side.

How photos are named

• Your name, cleaned so every computer can save it: one photo is summer-picnic.jpg, a batch is summer-picnic_1.jpg, summer-picnic_2.jpg and so on, in the order shown.
• The file’s own words, when it has some: Cozy_Living-Room_v2 final (1).png becomes cozy-living-room.jpg. Numbers, dates and the words cameras and apps add (IMG, DSC, PXL, Screenshot, WhatsApp Image, copy, final) are left out.
• Words from the picture, when the file name says nothing: its main colour and its light, such as golden-honey-afternoon.jpg or soft-sage-morning.jpg. This is worked out on your device from the colours. No AI and no server sees your photo.

Saving on a phone

On an iPhone or an Android phone, “Save to Photos” opens the share sheet with every photo in it, so the whole batch goes to your library in one tap. Photos keeps the picture but not the file name. “Save to Files” keeps the names (a batch saves as one .zip). Very large photos are saved at up to 16.7 megapixels, the biggest picture an iPhone’s browser can work on; a 48 MP iPhone photo comes out at about 3,550 × 4,730.

Making it a pin

Pinterest’s product specs say: We recommend using a 2:3 aspect ratio, or 1000 x 1500 pixels. and Pins with an aspect ratio greater than 2:3 might get cut off in people’s feeds. Pick Pin 2:3 and each photo is cut to the middle 2:3 and saved at 1000 × 1500. A photo smaller than that is cut but never enlarged. To add a title on top, open it in the free Pin Designer.
