Once the background plate has been shot, we need to carefully study it to…determine how to light our object. What is the sun and shadow direction? What…are the darkest darks, and the brightest brights?…Let's open the following image, which can be found in the sourceimages directory.…Notice in the image, we chose that the shadows are not fully black, and that the…color of the sun is warm, not midday white.…We need to take this into consideration when setting up our lighting.…A good photographer will get the right lighting, framing, and lensing, but there…will typically need to be further enhancements on the image.…
The great thing about shooting RAW is that with the 32-bit file format, there is…plenty of pixel information to manipulate.…There are several ways we can color correct an image. We can do it now in…Photoshop, or we can do it in our composite.…Here is a quick way to color correct the RAW image in Photoshop.…Let's close our preview. We notice in our sourceimages directory our Camera RAW…
