Old Photo Effect

What makes a photograph look old

Old prints have a recognisable set of characteristics, and an effect that reproduces all of them looks convincing while one that reproduces only the colour does not. They fade, so the blacks lift towards grey and the whole image loses contrast. They pick up a colour cast, usually warm yellow or brown, from the paper and the storage environment. They have grain from silver halide that has grown in the print. They are often scratched, creased, or spotted. And the edges often vignette as the mount yellows unevenly.

NoteFading is the most important characteristic. Colour cast without fading looks like a filter.

Fading matters more than the sepia

Sepia toning is the part people recognise, and it is the part that matters least. A faded colour photograph from the 1970s is recognisable because of low contrast, lifted blacks, and a yellow cast, not because it is brown. Applying a sepia to a modern image with full contrast produces something that looks like a filter applied yesterday, which is a different and less convincing effect. Reducing the contrast and lifting the blacks first, and only then adding the cast, is what produces something that reads as genuinely old.

• Reduce contrast and lift the blacks first. That is what reads as old.
• Add the sepia or yellow cast afterwards.
• Sepia on a full contrast image looks like a filter applied recently.
• Faded colour is more convincing than a uniformly brown image.

NoteFading is the characteristic that sells the effect. Sepia alone is the weakest part.

Grain has to be the right kind

Digital sensor noise and film grain are not the same thing, and using one to imitate the other gives away the effect. Sensor noise is fine, colourful, and evenly distributed across the frame, and it appears in the shadows most. Film grain is coarser, more visible in the midtones, and has a slight clumping structure from the silver halide crystals. A convincing grain layer is coarser than a noise filter produces by default and is applied more evenly, which is why a dedicated grain looks better than a generic noise filter.

• Film grain is coarser than digital sensor noise.
• Film grain is most visible in the midtones, not the shadows.
• Sensor noise is fine, colourful, and concentrated in shadows.
• Using sensor noise to imitate film gives the effect away.

Damage cannot be done well with a global filter

Scratches, creases, and stains are specific to particular areas of a print, and a global filter that adds them uniformly across the frame looks obviously artificial, because real damage is scattered unevenly and clustered near the edges and corners where a print is handled. Producing convincing damage requires either an overlay placed in specific positions, or a mask that limits the effect to a region. If that is not available, the honest choice is to skip the damage and do a good job on the fading, cast, and grain, which between them carry most of the effect.

• Real damage is uneven and clusters near edges and corners.
• A global scratch overlay applied uniformly looks artificial.
• Convincing damage needs a placed overlay or a region mask.
• Without that, do the fading, cast, and grain well and skip the damage.

NoteDamage done globally looks fake. Fading, cast, and grain carry most of the effect without it.
