HDR photos with the GIMP

Step 10 Recap- steps for creating brightness-mapped HDR

- Take stock photos- one exposed normally, one 1 stop underexposed, one 1 stop overexposed, from a tripod.

- Open middle image as background
- Open dark image, copy, paste into new layer in composite image, rename layer "Dark"
- Desaturate dark image
- Adjust curves on dark image to set levels
- Create a layer mask on Dark layer, copy monochrome dark stock image, paste in to layer mask and anchor
- Do the same for the light image- open, copy, paste into new layer, rename layer "Light", desaturate original stock image
- Invert colours in stock image, adjust curves if necessary
- Create layer mask on Light layer, paste inverted greyscale light image into it, anchor
- Save image
