Years will pass where you guess what your video camera's direct exposure latitude may be, you may wonder why in some shots the complexion has gone grey. You may desire to know if you can shoot that scene at midday, or what those night shots will come out like and what different ISOs do to the detail and colour of a scene.
If you are using a canon point and shoot video camera, I can still conserve you from buying a new camera. Attempt utilizing CHDK (canon hack advancement kit)if your camera is not too outdated. Discover more about that below. I'll have to ask forgiveness to Nikon users as I don't have a service for you yet.
Lets have a look at how a proper direct exposure works. The shutter speed, in a wedding event for example, will freeze the movement of the topics, so that the images appear sharp and pleasing to the eye. So, the shutter speed determines for how long the light impacts the sensor on the electronic camera, and the aperture affects how much light hits the sensor. So the combination of just how much light strikes the sensing unit for for how long determines by the shutter speed, provides us an appropriate direct exposure.
The cam will be in manual mode, so set the shutter speed so you get proper exposure at a low-ish fstop (maybe f4). Then, change the fstop to greater numbers so you are letting less light in, gradually under exposing. Ideally you wish to close down a minimum of 5stops. As in the highlight test, expose at each 1/3 stop closing the lens up to minimum aperture (f22 here or whatever your lens can). You will keep in mind on the back of your video camera the image starting with out burnt out whites, then getting darker and eventually losing a great deal of information as you go through the steps.
Assessment of shadow and highlights. This is where you need your opinions. Open all of the files in your editing software application. I use Adobe Lightroom Free Alternatives as it enables for fast evaluation of the raw files. Ensure all presets or effects are off. A great quality, appropriately adjusted screen will ensure you are seeing the detail you ought to see. Lots of monitors struggle at the extremes and we are evaluating extremes.
The primary program that we utilize at work for graphic style is Adobe's Photoshop. If you don't understand, Photoshop is the end all, to be all program. Every expert graphic designer either utilizes it or wants they did. They are the exception to the world if they do not. We utilize Photoshop for every visual print or web graphic, and even some in our DVD menus. Our message inserts, advertisements, and some more things are all finished with Photoshop. I'll get to the 'more things' later.
If the scene falls beyond these borders. -You need to accept a less than ideal outcome. Which you will comprehend what it will appear like as you will have performed this test. -You can change the lighting by utilizing rearranging, reflectors, or flash to control the dynamic variety of the scene. -Or utilize HDR methods to take several frames differing the exposure for the issue areas, and integrate the frames in post production.
