Paint Modes - S


Saturation

Secondary : No

Uses colour : No

Options : -256 to 256

Description :

Raise or lower the saturation of a selected part of the image. Colours get stronger with higher saturation and weaker with low saturation. If you raise saturation heavily then very light colours may appear to turn to random colours. This is not a fault with Saturation but an inevitable side effect of how saturation works. If you Blur the image before using saturation you may solve this problem.

Sharpen

Secondary : No

Uses paint : No

Options : Sharpness (1 to 9)

Description :

Edges in the current picture are detected and sharpened to enhance the image. Larger values produce a stronger sharpening effect.

NOTE.

The original Sharpen provided with Photogenics 1.0/1.1 worked differently. This can be accessed by using the Matrix paintmode and loading the 'old_sharpen' matrix.

ShiftHue

Secondary : No

Uses paint : No

Options : Shift amount (degrees)

Description :

Any colour can be described as a combination of three components - Hue, Saturation and Value. Shifting the hue can be used to alter the colour component only.

ShiftRGB

Secondary : No

UsesPaint : No

Options : Backwards Yes/No

Description :

Photogenics images are stored as RGB (Red Green Blue) data. By swapping the R, G and B values different false-colour effects can be produced. Default is R goes to G, G goes to B and B goes to R. This direction can be reversed with the Backwards option.

Solarize

Secondary : No

Uses colour : No

Options : Normal/Inverse

Description :

This simulates a classical photographic trick, deliberately exposing a negative before developing to produce unusual colouring and shading. This will enhance the darker colours but invert the brighter colours. You can select between normal and inverse solarize. Inverse solarize is exactly the same as doing normal solarize and then inverting it.

Split

Secondary : No

Uses colour : No

Options : Direction

Description :

Splits the image into four groups of pixels and moves them in different directions by the specified amount.

Stellate

Secondary : No

Uses colour : No

Options : Size

Description :

Uses an algorithmn similar to Maximum, but makes star-shaped patterns crystallise out of your image. Use with a high size setting and set your transparency high for lens-star type effects.
