I've been using a photometer since I was forteen. I have a pretty collection of pbotometers and colormeters. I am used to match lightings and other sources using my eyes but I use those devices, just in case. Today when I deploy the lights on the stage I use my mobile phone I take a snap and I use it to check the lighting and colors. It's completly reliable. Colormeters only are useful to realise how bad are the lights we hired..
Henry Matisse: "My bigest concern when draw a stroke of color is what color do I have to draw next to it"
A.Tarkowsky: "Real image and its felling is rendered in black an white, color was created for commercial purposes."
Who would dare to contradict them? Color is a very complicated issue, not a game to play with. To enhance is not to invent.
I beg your pardon for my bad translation.
Why don't they leave old films as they were creted instead of ruining them. Gerg Toland's generation were pioneers in their field, masters who developed this beloved industrie. Now a day, someone with basic knowledges of filmography and photography dares to ammend those films with a software. Pressing down a key they are eager to make easy money instead of producing their own films. I think that they are making fun of the real art.
My lens must be irretrievably dirty to wip any tissue over it. But I am a photgrapher and most of the time I have to work in extreme conditions: Heavy rain and dusty environments. First at all; all my lenses have an UV protective filter that doesn't affect image quality or frontal sun flares. I never change lenses in those conditions. All my lenses are always shut with their caps. I have a maniatic obsession for not to lay my cameras onto the ground resting over the hood as all press photographers do. Wipping a filter is not the same than wipping a frontal lens. But lenses are strong and good lenses have an antiscratching covering, they endure more than we think, Better don't risk. That's up to you.
If the speaker could speak a little slower non English listeners would understand more.
