The ideal scenario is to have the aircraft on the ramp (or an aerial shot) with the least amount of distractions possible. Images taken in the morning or near sunset are best as this is the Golden Hour and is the best light. Keep the aircraft away from others if possible and if you can wash the ramp with a hose. Take a lower angle looking up for the most dramatic look. Here are samples of images I have rendered. This is NOT an app. I work in Adobe photoshop and have to manually take out distractions such as power lines, buildings, wires etc. Then I have to apply artistic set of tools, lighting, exposure and coloring to get the image. This is a great hangar or home piece that you can be proud to mount.
