Medium Format
Medium format refers to the size of your roll of film (or if you’re talking digital, it’s the size of the camera sensor). It really just means that you are shooting on a bigger piece of film than you do with a 35mm camera. The increased size of medium format film means a much larger negative. This will give you finer details and less grain.
Choosing your Right Medium Format Camera
Twin Lens Reflex (TLRS)
TLRs use two objective lens of the same focal length. The photographic objective lens is the one that is used to take the picture. The other lens, called the view lens, is connected to the viewfinder. Most TLRs are fixed focal length, and the more expensive models may incorporate a rudimentary room function. Most TLRs use a leaf shutter system, resulting in high speeds, quiet operation and low shutter vibration. There are also close-up, wide angle and telephoto adapters for TLRs.
Some popular TLRS cameras are: Yashica MAT-124G, Rolleiflex 2.8F, Minolta Autocord and Mamiya C330
Rangefinder
Rangefinder cameras are medium format cameras with a range finder. This negates the waistline, viewing that most TLRs carry. They are also much smaller than TLRs, and allow for easier point and shoot photographs. They tend to have limited focusing ranges, and do not have lenses larger than 180mm or 200mm. Rangefinders are quieter and easier to focus in dim light. They are mostly fixed lens models, but higher range models also provide for interchangeability.
Some popular rangefinder cameras are: Fujica G690, Mamiya 6/7, Bronica RF645, Norita 66 and Pentax 67

About Atem Mini
Transitions
Available transitions include:
-
Cut: When you press the cut button, ATEM instantly changes from your current program source to the preview source. Cuts can be performed by directly selecting sources or by pressing the cut button to switch to the next source.
-
Mix: The mix, or dissolve, gradually transitions from one source to the next by creating a smooth blend. You can set custom timings to manually blend the transition.
-
Dip: Just like mix transitions, a dip transition is a gradual blend that includes either a solid color, graphic, or another clip between the two video sources. Dips to black or white between sources are the most popular, or you can use logos or sponsor graphics.
-
Wipe: Built-in wipe patterns include circles, diamonds, squares, and more. Shapes and patterns can be inverted or softened, and can even have customized colored borders.
-
DVE: With the powerful built-in Digital Video Effects processor, or DVE, you can push, spin, squeeze, or swoosh your live video from one camera to the next with incredible built-in transitions. DVE transitions can be flip-flopped and reversed, giving you even more transition options.
Upstream Keyer
Layer live video over other video sources or graphics with the Upstream Keyer. You can use luma key, linear key, pattern key, or shoot against a green screen and use chroma key to instantly composite the video over virtual sets.
-
Luma key: Luma keys work best with high-contrast images, like white elements on a black background, so you can use the contrast to cut the black background and replace it with live video or graphics.
-
Linear key: Get clean, high-quality results with linear keying by using two separate sources for the fill and the key to create one video image. The fill signal contains the video to be stacked over the background, while the key signal contains a gray scale mask to cut out, or mask, the area to be filled.
-
Chroma key: Used every day for TV weather forecasts, chroma keys are a powerful way of combining live images in real time. The presenter typically stands in front of a green or blue background and the chroma keyer will remove only that color and combine it with another image, such as a video or graphic.
-
Pattern key: Combine live images with any of the built-in wipe patterns to combine live images or graphics with geometric shapes. You get full control over softness, symmetry, size, and position to create unique picture-in-picture effects that can be transitioned to as easily as any live source.
Downstream Keyers
The ATEM Mini switcher includes one downstream keyer, so you can add high-quality graphics like logos, bugs, and titles from the built-in media player over the live stream program output. Downstream keyers are the last layers of keying, so they overlay all video switched to the main program output.
Audio Mixer
The built-in audio mixer lets you control both camera and external audio with precision level and balance adjustments on all six available audio inputs and two channels. The mixer features selectable On/Off/Audio-Follow-Video per channel, plus it has separate gain control per channel, level and peak metering, and new Fairlight audio enhancements such as compressor, gate, limiter, six bands of parametric EQ, and master gain control.
Monitor Output
The HDMI monitor output allows you to see your sources, graphics, preview, and program output on a single screen.
Media Player
Eliminate external character generators by storing up to 20 broadcast quality RGBA graphic files in the media pool. The one media player appears as input sources to your switcher. You can transition to graphics as full-frame video, or feed them to the keyers for overlaying video. Popular image formats such as PNG, TGA, BMP, GIF, JPEG, and TIFF are supported.
