Feature Requests / Re: Key Tone -- Perfect Exposure
June 25, 2015, 05:58:11 PM
Thanks for your info dmilligan

but the matrix zone system its very different to the zone system. the matrix zone system proposed by Michael Freeman its a grid analysis and convert the image into the 67 squares in grayscale to identify the key tones like reference for a correct exposure.

For a deep explanation, in this link can download the book http://soul-foto.ru/knigi_po_fotografii/Michael%20Freeman.%20Perfect%20Exposure.%20The%20professional%20guide%20to%20capturing%20perfect%20digital%20photographs.%202009.pdf.html



Thank you so mouch

Feature Requests / Key Tone -- Perfect Exposure
June 24, 2015, 05:47:31 AM
Hi ML Team

In the Book The Perfect Exposure by Michael Freeman pages 16-17, 67-113 this photographer use a grayscale mosaic zone system to help a identify a Key Tones of scene for a Perfect Exposure, the question is if its possible development a tool on LV that convert the scene in mosaic grayscale according to this method.

thank you!!!

Hi ML Developers

Will be technically possible to development ML Hidden Picture View Module capable of show select snapshot 2-3 seconds on the display; but then only you can see the picture when download the files on the PC?

thanks again for your efforts and majestic works!!!

Yes ansius the M Monochrome its a special monochromatic 3CCD sensor instead of CMOS Color array EOS Sensor, if its technically possible; the request its on the way that enhance the mono picture style to a Module with deep controls over the B&W..

Hi ML Developers

It´s possible development a Module to B&W Video and Still Photography with controls to enhance de luma channel and/or raw data capabilities in the same way of  the Leica M Monochrome ( "...The M Monochrom features a full-frame, 35 mm format sensor developed especially for black-and white photography. In contrast to conventional sensors, it has no need for color filters for individual pixels, and therefore requires no interpolation for the calculation of luminance values. This means that raw data and even JPEG image files from the M Monochrom can be used directly and without any further image processing. This speeds up the workflow, and enables photographers to capture images with greater brilliance, superior sharpness, enhanced tonal gradation, and resolution that can equal the quality of medium format. Due to their low compression value, JPEG files from the camera also satisfy professional demands...")

Thanks in advantage for your wonderfull works!!!

Duplicate Questions / Focus Patterns for Canon 6D.113
January 07, 2015, 03:23:03 AM


Hi ML Friends

It´s possible enable the Focus Patterns Module for the next build on 6D.113?

This is a majestic tool!!!

Thanks a lot!!!

Hi ML Friends

It´s possible enable the Bulb/Focus Ramping Module for the next build on 6D.113?

This is a majestic tool!!!

Thanks a lot!!!

Thank you eduperez for your comments...

The actual  ML for the 6D.113 Mirror LockUp (MLU) configuration only set up for hanheld shutters between 1/2...1/125 option, for me is interesting activated the mirror lockup only when the shutter speed was under the equivalent focal lens to avoid blur for camera shake.

Hello Magic Lantern People

First let me give a biggest thanks for the majestic works that you are make it.

I have a feature request for a 6D.113 firmware if its possible.

The photographer well know that to avoid a blur effect of the Camera Shake you need activated the MLU when the Shutter Speed (SS) is under the Focal Length of the Lens (FLL) (or effective focal length, if you're using a crop sensor camera).

The empirical formula for a FullFrame camera is SS=1/FFL or for and for  a crop sensor SS=1/(crop factor x FFL). Of course, many Canon Lenses have built-in  Image Stabilization (IS) features that reduce the effects of shake and allow you to use shutter speeds two to four steps slower than normal.

The question is if it possible write an algorithm that detect the Shutter Speed and relation whit the Focal Length of the Lens (FLL) when te IS its no actived or when we don't have a IS Lens for example:

For a FullFrame Camera like a Canon EOS 6D (6D.113), If I have a Canon EF 70-300 ƒ/3.5-5.6 or wathever EF Lens and I need a Shutter Speed of 1/125sec if the Focal Length of the lens is 70mm I don't need a MLU but if I need a 300mm the MLU need activated. the MLU Auto algorithm  must be detect this situation and activated the MLU; this  program must be independent for ƒ/number  and ISO that we need.

For a APS-C Canon Crop Sensor  (and maybe this is another feature request) the algorithm must be multiply the  Focal Length of the Lens by the crop factor to obtain the effective focal length if the Lens is a Canon EF but directly if the lens is a Canon EF-S or Canon EF-M.


In general this must be different feature request one for the fullframe sensor and another for the crop sensor but this is the idea

here some internet links documentations about this:

Thanks a lot Majestic People ;)

Best regards!!!
