Photisan

Handcrafted photo development and editing.

Photisan is a photo editor for Mac, with no artificial intelligence. You develop the RAW and edit with layers in the same window, with tools built on how photography works.

For macOS 11 or later. Made for Apple Silicon.

No artificial intelligence.
By choice.

Photisan uses no AI: not to generate images, not to decide for you. No replaced skies, no automatic skin retouching, no suggestions from a neural network. What you see in your photo is what you did.

Every tool follows the rules of photography: light, emulsion, development. The ones that work on their own, like film conversion or quick selection, follow rules you can see and correct.

And your photos never leave your Mac: the app only goes online to check your license.

Developing isn't another module

Open the RAW and adjust it in the side panel: exposure, white balance, curves, colour and detail. The development stays a layer of the document: you work on top with layers and masks, and move the exposure again whenever you like, without exporting or resorting to smart objects.

For Bayer and X-Trans sensors. Merge photos into HDR or panoramas and save them as DNG.

Layers panel: two layers of a RAW inside a group, under an adjustment layer

Cinema colour

Colour grading tints and exposes the shadows, midtones and highlights separately, with soft transitions by exposure. With the qualifier you isolate a colour and work on it alone, as in a film colour suite.

Colour grading: lift, gamma, gain and offset wheels, with the vectorscope

Convert your negatives

Open the scan, or the photo you took of the negative with your camera, and Photisan converts it like a minilab. Tell it which film it was to use its real curves, and choose how the lab prints it: Frontier style, Noritsu style or neutral.

Colour negative, black and white negative, and slide.

  1. Recognises the orange mask
  2. Measures the film base
  3. Balances the greys
  4. Sets the exposure

The tools you already know

Layers, groups, masks and blend modes. Quick selection that follows edges, refine edge for hair, liquify, patch, curves and perspective transform. Work in RGB, CMYK, Lab or greyscale.

Opens and saves PSD

Your documents are saved as PSD, with layers, groups, masks and blend modes, in 8 or 16 bits. Open them in Photoshop when you need to, and bring the ones you already have into Photisan.

Light

The download is under 30 MB. Adjustments are computed on your Mac's graphics card and applied to the full photo, not to a reduced copy.

24 films, modelled from their datasheets

These aren't colour filters. Each simulation reproduces how the emulsion responds: each layer's sensitivity to colour, how the layers hold each other back during development, their characteristic curves and their grain, measured for 35 mm, medium format or large format. Overexpose or underexpose, and each film answers with its own latitude.

Questions

Does Photisan use artificial intelligence?

No. No feature uses artificial intelligence models, either to generate or to decide. That's a choice: Photisan is for people who want to make their photos with their own hands.

What does the trial include?

Everything. For 14 days you can open, edit, save and export with no limits. When it ends, the app still opens and shows your photos, but you need a license to save and export.

What happens if I cancel the subscription?

Nothing stops working: you keep using, forever and on your two Macs, the versions released while you were subscribed. You just stop getting new ones. If you subscribe again, you get every update again.

Do I need to be online?

Only to activate the license or start the trial. After that, Photisan works offline for up to 14 days in a row, and renews the license by itself when you're back online.

Can I move to another Mac?

Yes. Deactivate the license in Settings › License and activate it on the other Mac with your key.

Does it open my Photoshop files?

Yes, it opens and saves PSD with layers, groups, masks and blend modes. What Photisan can't reproduce, such as editable text or smart objects, opens as pixels. The app tells you what would change and, the first time, saves under another name so the original stays untouched.

Is there a Windows version?

For now, Photisan is Mac only.
