Red Hot Heat Effect in Gimp
To apply a nice Red Hot Heat effect to an image simply follow these steps:
- Open Image
- Colours > colourise
- Adjust the Hue value to around 200, basically you want a good solid blue colour, sway more to light than dark though.
- Adjust the Saturation to around 75
- You can leave the lightness at 0, but probably don’t adjust it more than 20 either way
- Next Duplicate this layer
- Then go Filters > Blur > Gaussian Blur... and set it to about 75
- Now change the mode of the blurred layer to Overlay and and then merge the layer down
- Duplicate this layer again
- Go to Filters > Blur > Motion Blur...
- Set the length to around 50
- Set the angle to around 90
- Again change the mode of the blurred layer to Overlay and and then merge the layer down
- Next add new white layer and apply a Difference Mode to it.
