Scatter: x-ray beam is deflected from its path by interaction with matter (dangerous) What does the mA control- quantity or quality of x-rays? quantity What does the kVp control- quantity or quality of x-rays? quality What control panel setting controls contrast? kVp (kilovoltage peak) Describe Ideal Contrast. Secondary: x-radiation that is created when the primary beam interacts with matter (patient tissue) Only inspiration will take you that most important step.What is thermionic emission? Release of electrons from tungsten filament when it is heated electrons stay in a cloud around the filament What happens when the high voltage circuit is activated? Electrons in cloud are accelerated across x-ray tube to anode When are x-rays produced? When electrons travel from cathode to anode and into the tungsten target How much heat (%) and x-rays (%) is produced? Heat: 99% X-ray: 1% Define Primary, Secondary and Scatter Radiation Primary: made up of x-rays that come from the target of the x-ray tube Look at Hopper, Rockwell, Picasso, Lowry - so many! It's a never-ending struggle for me to get something looking how I want to imagine things as being. You can find more Replichrome based shots on my flickr photostream at you're curious. It's part of my small town America project. Here's where I'm at with Replichrome at the moment, using their Ektarchrome setting tweaked somewhat a little further by me. Bruce Davidson is grungy and popping with gleaming streaks amidst the muddy colour.

For example, Saul Leiter and Ernst Haas employ very inky, slick, vivid colours with lots of black. Then after being inspired by them see how close you can get to that feeling you felt when you saw a photograph that blew you away. see how they use colour and black and white and discover your favourites. I'm talking Stephen Shore, Gregory Crewdson, Dorothea Lange, William Eggleston, Lee Miller, Alec Soth, Don McCullin, Garry Winogrand, Saul Leiter, Fred Herzog, Bruce Davidson. Then, hit the library and go through as many photography books by the masters as you can find. Learn how each one effects a photograph and how they play off each other. Still, I'm getting closer.īut I think the most important thing to take away from Replichrome, VSCO and all the others isn't the presets itself, but the education they give you in using Lightroom. But I have to learn to accept that I can't really achieve that on a Fuji X camera, and that if I want Stephen Shore quality I should just scrimp and save for the next who knows how long and get a plate camera.

The only thing is that no matter how much I like them, I can't quite get close enough to that dream preset that will make my photographs have the same colour and tonality and breadth as Stephen Shore. But the Replichrome ones are cheaper overall, which is nice. The difference isn't huge, but it's there.

You'll find Replichrome's simulations a little more dirty or grungy than VSCO's, which tend to be a little slicker and more fashion or portrait friendly. I love their 'film curve 2' for removing a bit of shadow detail as well. But theirs are easy to use and you can stack them quite easily to get certain effects. I dig their other film presets too, but I always find myself tweaking them slightly for personal taste. (Disclaimer, I got the second one for free in exchange for giving them a few photographs for their website.) I'm wedded to their black and white Kodak BW 400CN setting. Personally I use and enjoy Replichrome's Film Preset packages I & II.
