RED Tools is a convenient reference tool designed for use by filmmakers and camera operators to outline best practices in camera set-up for a variety of shooting situations. Each tool is customizable based on a selected RED camera and sensor type. Standard film formats are also included for comparison. RED Tools is also included in the RED Control app, which also provides free, full-featured camera control and video streaming for RED’s latest DSMC3 products. TOOLS INCLUDED: CROP FACTOR Preview how a given focal length will appear depending on resolution setting and sensor type. Illustration depicts viewable area relative to a traditional 35 mm stills photography sensor by default, but other reference sensors are selectable within the drop-down menu. R3D RECORDING TIME Evaluate the video data rate and available recording time based on your RED camera settings. This can help you understand media requirements and production costs in advance of a shoot. FLICKER FREE VIDEO Find a flicker-free shutter speed and frame rate combination when shooting under artificial lighting. DEPTH OF FIELD Understand how various camera settings influence depth of field. PANNING SPEED Estimate the panning speed where judder will likely become too pronounced. The goal is to provide a more accessible tool than the charts and tables commonly referenced in cinematography manuals. It uses the standard rule of thumb that camera panning should not cause objects to transit the entire horizontal extent of an image in any less than seven seconds. EXPOSURE Assist with exposure when one camera setting has to change. Example usage scenarios include when a higher frame rate needs to be used for slow motion, when the T-stop has to change for depth of field, or when the shutter angle has to change to minimize flickering in artificial light. NIKKOR Z Lens Coverage Use this tool to understand how NIKKOR Z lenses will look on your RED Z Mount camera bodies. The tool shows the extent the light will fall off at different sensor formats, and if any hard vignetting occurs.

Magic Canonic ViewFinder presents you a precise framing preview for the real camera/lens combination you'll be shooting with, right where you stand with your iPhone / iPad. It simulates the field of view of digital cameras or lens and can help thousands of professionals in filmmaking at the preproduction. PLEASE READ: this app does not turn your Apple device into an external monitor, but operates as a stand-alone director's viewfinder. The app contains ad banners, which can be turned off with additional in-app purchase (in 'About the App' menu). The app is a digital directors viewfinder - it helps you see the exact field of view for your future shot. Select the camera from the menu and rotate the wheel to select the focal length of the lens. Supported cameras: Full Frame (in both photo mode 3:2 and video mode 16:9) - EOS-1D X Mark II - EOS 5D Mark IV, III, II, I - EOS 1D C, 5DS, 5DS R, 6D APS-C cropped sensor (photo mode 3:2 / video mode 16:9) - EOS 7D M II and I, 80D, 77D (9000D), Rebel T7i (800D), etc - EOS M6 / M5 / M10 / M3 - EOS C100, C300, C500, C300 MkII - XA10, XF100 Magic ViewFinder simulates using tele adapters or anamorphic optics on your camera (see menu). From the menu you can also select the aspect ratio of the frame guide overlaying your image. Magic ViewFinder lets you apply color presets (aka LUTs) to the live picture, which brings you even closer to the final shot. You may capture the image or video for future reference, with additional data like the focal length, date/time and camera / lens information. While capturing, you may lock exposure and turn on/off AF to better control the captured picture. You can turn on the AF mode, or lock the focus temporarily. You can also tap the live screen to focus on particular objects. White balance may work in Auto, Locked or Manual mode. If the field of view of your real camera is wider than your in-device camera, the app adds 'padding' around the image, since the device cannot 'see' what is beyond. Please note that position of your iPhone or iPad should correspond to the 'nodal point' of your real lens, which is somewhere in the middle of the lens. This point is, so to speak, the weighted center of the optics. Ad policy: The ads are designed to appear non-intrusively. Ads can be turned off (see below).
