# Fotografisch bewerken - Workflow

## Afbeeldingsbewerking/Hulpmiddelen voor workflow

### Een standaard voorstel voor workflow

When performing a basic workflow, the primary areas for consideration are:

1. Exposure: White Balance

2. Color: White Balance

3. Black and white points: White Balance or Adjust Levels

4. Contrast: Adjust Curves

5. Saturation: White Balance or Vivid or Hue/Saturation/Lightness

6. Resizing (interpolation) : Change Size

7. Sharpening

8. Digital Asset Management (applying tags, captions, rating, geolocation, save under new name)

We recommend this sequence of image editing steps to ensure optimum photographic quality for the end product. In particular, never do sharpening before the last step. And we recommend using a lossless format like PNG or TIFF for storing photographs. Otherwise you'll lose a bit every time you save the results. If you can afford it, use 16 bit/channel for your best shots. If you want to change color space, in particular if you want to work in CIEL*a*b, 16 bit per channel are required to avoid truncation effects.

If you swap step 4 and 5, which is well possible if the initial contrast is already very good, you can do the first 4 adjustment in the same plugin, the white balance

Many of the tools you may need for photographic editing are included with &digikam;. Their description follows here.

### Inleiding tot algemene mogelijkheden van bewerkingshulpmiddelen

All Image Editor tools like Sharpen, Blur, Noise Reduction, Refocus, Unsharp Mask, &etc; use a common dialog style that previews the effect before applying the filter to the current image. Below you see the "Apply Texture" tool in action using this common dialog layout:

Het hulpmiddel textuur toepassen in actie

- (1): de zeven knoppen linksboven selecteren de vergelijkingsstijl van het voorbeeldgebied. De modi zijn:

  - Oorspronkelijke afbeelding

  - Split vertically without duplication. The left area shows the original whereas the right side shows the filter applied to the continuation of the selected zoom.

  - Split horizontally without duplication. The top area shows the original whereas the lower area shows the filter applied to the continuation of the selected zoom.

  - Split vertically. The left area shows the original and the right one the filter effect for comparison.

  - Split horizontally. The top area shows the original and the lower one the filter effect for comparison.

  - Effect preview. This is a live effect preview without comparison.

  - 'Mouse over' style: preview when mouse is off the preview (in the settings area), otherwise shows original.

- (2): There are two buttons that can be toggled to show over or underexposure. The colors can be customized in the general setup page.

- (3): The preview selector frame. Click and drag with the mouse on the floating frame to move it on the image. The preview area on the left of dialog is updated accordingly.

- (4): The filter or plugin settings area.

- (5): At the lower left corner: there is help and a reset to defaults button (all settings are remembered from the last use of the plugin).

- (6): Er is een voortgangsindicatie voor plugins met bijbehorende berekeningen.

## Processing RAW image files, RAW work-flow

A typical RAW workflow with &digikam; may follow these steps:

- De voorkeuren voor RAW-conversie en kleurbeheer instellen

  - haal de ICC-kleurprofielen voor de camera, scherm en printer op

  - &digikam; juist instellen door een kleurwerkruimte te definiëren

- Instelling van witpunt van camera

- Demosaicing (includes interpolation, noise filtering and chromatic aberration correction)

- Conversie naar kleurruimte

- Gammacorrectie, toon overeen laten komen

- Kleurprofieltoewijzing

- Dynamic range expansion (optional)

- Ga door met standaard workflow

From there everything is simple, select a RAW image and open it in the editor. The color management widget will be displayed after the image has been processed in order to adjust color rendering. Without color management all images are very dark, this is normal. You can experiment the various profiles you have in order to select the best input profile according to your image (some tends to be very neutral, even a bit dull, some gives more saturated results, &etc;).
