The application

Edits are a recipe,never the file

Every change is stored beside the raw, so the original is always there.

Lighttable first

Import a card, rate and colour-label, and find the frames worth working on.

The darkroom modules

Exposure, colour balance, denoise and lens correction, in a history you can rewind.

Export the set

Apply a style to a hundred frames and write JPEGs out in one pass.

How you run it

Every defaultis one override away

The session reads its settings from the environment, so you set them on the start line.

VNC_PASSWORDWhat the tab asks for. It ships as dxflow, and everyone reading this knows that.
PANEL and TASKBARBoth hidden, so the lighttable has the whole screen. Show either one to get the desktop back.
AUDIOOff here. Turn it on and the desktop sound is streamed beside the picture.
start it your way

$ dxflow workflow start darktable --override env.app.VNC_PASSWORD=something-long

$ dxflow workflow start darktable --override env.app.TASKBAR=show --link

Good to know

The raw fileis never touched

Everything you do is an edit history beside the image, which is what makes a shared volume a sensible place to keep a shoot.

Non-destructive by design

The developed look lives in a sidecar and the database. Go back a year later and every step is still adjustable.

Export is where the time goes

Culling is light; developing a set of raws is not. More cores turn a batch export from a coffee break into a moment.

Keep the library on the volume

Raws, sidecars and the database under /volume means the catalogue is still yours at the next start.

The image

Pulled once,then it stays

darktable arrives as one image. This is what comes down the first time, and what the disk should have free for it.

What it asks for

What it wants,and what it needs

The definition asks for 4 cores and 8 GB. The image comes up on less than that, and a start given --fit trims the ask to whatever the machine actually has.

The ask is not the floorThe definition writes down what suits the work. The image itself starts on less, which is what the second figure is.
--fit caps it to the hostA start given --fit trims each step to what the machine actually has, for that start alone. The definition is never rewritten.
