Preparing an old photo for a new frame

The gap between “I have this photo” and “this photo is on the wall” contains about four decisions, and most people discover them in the wrong order, usually after buying the frame.

Capture it properly first

Everything downstream depends on this, and a phone is genuinely good enough if you do three things:

• Flat, in daylight, away from the window. Direct sun blows out the highlights. A bright room with the print on a table beside the window is ideal.
• Camera parallel to the print. Stand over it, not beside it. A photo taken at an angle has to be un-skewed later, and that costs detail.
• Fill the frame, then step back slightly. Get the whole print plus a little margin. Cropping later is free. Recovering an edge you cut off is not.

If the print is in an album with a plastic film over it, take it out. That film is why your capture looks foggy.

Know what restoration can and cannot recover

It can deal with creases, tears, scratches, dust, fading and colour casts, and it can pull back a surprising amount of lost contrast.

It cannot invent detail that was never captured. If a face occupies twelve pixels of a badly focused snapshot, no process recovers who that was. What it can do is produce a confident-looking person who is not them, which is worse than leaving it blurred. Be suspicious of any result that gives you more than the original could have held.

Keep the original either way. A restored version should always be a second file, never a replacement, so that anyone looking at it later can compare.

Then the ratio problem

This is the one that catches people. Old prints are rarely the shape of modern frames.

A typical 1960s snapshot is close to 7:5. A standard modern frame is often 4:3, or A-sizes in Europe, or 8×10 inches, which is 5:4. None of these match. So something has to give:

• Crop. You lose the edges. Fine for a portrait with room around it, bad for a group shot where somebody is standing at the edge, which is exactly where the person nobody has identified usually is.
• Widen the frame. Extend the scene outward so the photo fills the new shape without cutting anybody. This works well for backgrounds like sky, walls, grass and roads, and badly for anything with detail that has to be right.
• Mount it. Use a mount board so the print keeps its own shape inside a frame of a different one. This is what a framer will suggest, and it is usually the honest answer for a photo that matters.

Decide the ratio before you prepare the file, not after. Measure the frame, or the mount aperture if you are using one, and work to that number.

Size it for print, not for screen

A file that looks perfect on a laptop can print soft. The rough rule is 300 pixels per inch of final print size: a 10-inch-wide print wants around 3000 pixels across.

If your capture cannot reach that, print smaller. A crisp 6×4 is better than a mushy A3, and nobody has ever stood in a hallway thinking a photo was too small.

Check it at arm’s length before you commit

Look at the file at 100%, then look at it small. Restoration artefacts that are invisible on a phone can be obvious at A3 on a wall in daylight. Faces are where you look first: check the eyes and the mouth, because that is where an over-processed result gives itself away.

Keep the trail

Whoever hangs this photo will not be the last person to care about it. Keep the original capture, the restored version and the print-ready file, and keep them connected, so the next person can see what was done and undo it if they disagree.
