“I know you are all busy filming but if I could have your attention for a few minutes whilst I explain the next step” The Professor bellowed out into the general chatter from the students filming. “Many muggles have attempted the process of converting black and white films into color for the modern generation. Although I don’t think it’s necessary and that the conversion may mean that the movies lose a little of their charm, the process is painstaking and originally involved hand painting directly onto the film frame. As technology evolved, the process became easier as they were able to digitally enhance using programming.”

“We are going to take advantage of our magical abilities and use a spell to convert our black and white films into color and vice versa.” He tapped the board as the Hollywood sign erased and a new set of words appeared.

“This is a simple variation on the color changing charm specifically designed for use in the developing fluid you have in your tanks. When you are ready, bring your film to the tanks and give the charm a try. Like this..”

The professor carefully removed the reel from its case and lowered it into his tank. “Colovaria Polychromatis” he enunciated clearly, pointing his wand at the fluid as it oddly bubbled and spat and dribbled over the side of the container like a potion having a temper tantrum before it settled back down. “You get the jist” He waved the experience off with a nonchalant wave of his hand, making a mental note to call the House Elves later to clean up the mess.
