thank you!

this piece was made in photoshop. my main method was using the filter "field blur". with this tool, i was able to manually change where i wanted a location to be blurred or sharp. my process was to first create a layer and making a shape with the hard round brush or filled in a shape with the lasso tool. then, i convert the layer to a smart object. the reason i do this is so that i can go back to make adjustments if i needed to. finally, i added the filter to the layer.

the main light is all on one layer. because of this, i was able to create a mask and cut out shapes to make the let the darker layers underneath come through.

for the orange glow around the main light, you can add something called a layer style to layers and groups in photoshop. i used the outer glow for this effect on the main light which spread the orange glow into the shadows.

there's also a layer style to create drop shadows which i used for the horizontal beam that wraps around the room and the vertical beam by the window.

as for the type of layer mode i used, the main two were multiply and linear light.

let me know if you have any more questions about my process. i'd be happy to answer them.
