|Detail - Starlight|
The background layer consists of the photo of a small hilltop covered by willows taken a couple of nights ago without a moon.
The mid ground is a castle I built a couple of years ago. It is looking a bit the worse for wear and the spiders had got in. I chose a silhouette to match the starlight night - the first picture had too much detail (thinking of using it with a moon).
Ensure you have a (sky) blue background and use the Photoshop cc.
Use the Quick Select tool to select and then cut the sky. Then add the castle by copying into a layer with the background. I then selectively deleted some of the castle wall to allow the tree shapes to reappear at the front of the castle - adding to that with brush strokes. I then used the layer-Matting tool to achieve a seamless juncture of the two layers.
A couple of fires were added with a flame brush - together with ash, embers and smoke.
Flames can be tricky to add - flames show a lot of variation. You need to add local reflections (in this case the fires cast a relatively small circle of light, which would have been largely out of sight, but which backlights the foreground tree/bush silhouette), smoke (where illuminated by other elements - the fire itself and other light sources), live embers (which tend to be in and below the prevailing drift of smoke), and ash (darker elements within the drift of smoke).
|Fire - detail|
I extended the smoke behind the castle layer to emphasise the silhouette.
The dodge tool helped brighten elements of the castle to reflect some of the fire and starlight.
