Improper exposure in any portion of your photos results in color distortion and disappointment.
It’s probably fair to say that the biggest challenge in photography is trying to get perfect exposure throughout every aspect of your entire photo. This is because of the camera’s inability to reproduce what the human eye sees. The human eye is dynamically adjusting for exposure – whereas the camera only contains a single aperture.
Even in a great photo, some portion will be improperly exposed relative to what the eye sees. Inaccurate exposure means inaccurate lighting – and inaccurate lighting means distorted colors.
Compounding this is the traditional method used to increase brightness – adjusting Luminance – which guarantees even further color distortion.
Perfectly Clear is the only solution that emulates in your photos the essential and correct missing eye function the camera lacks, while rigorously adhering to the physics principles of light. The result is Superior Photos and superior emotional impact on those who view your photos.
Proper Exposure is the Largest Challenge in Photography
Statistical studies have shown that as many as 90% of all photos taken have some sort of exposure challenges. Is this because the photographer taking the pictures is incompetent? Absolutely not. It’s simply a result of one of the 15 ways your camera distorts color.
How the camera’s Light Gathering Compromises Exposure
The challenge with exposure is intrinsic to camera design and has been from the beginning of photography. There’ll always be endemic exposure challenges as long as cameras have a single aperture and shutter settings. It’s impossible for a single aperture to open and close in a precise instant and properly expose everything in a photo. Photos include subjects/objects at different focal distances. Each often exposed to different amounts of light. Even the character of the light they’re exposed to could be different. How can a single aperture with a single shutter speed accurately represent this diverse information?
The camera operator, knowing the limitation of his single aperture, focuses the aperture on a particular subject/object in the photo and selects a unique shutter setting.
Although this is perfect behavior, the result of these actions means that some portion of the photo will be properly exposed and other parts not. So exposure in photography, digital or film camera, is a compromise.
The insurmountable challenge for the camera is that single aperture means that the camera has a fixed and restricted dynamic range. But the advantage of digital over film is that poor exposure can be overcome after the fact.
Your eye gathers light perfectly and so does Perfectly Clear
The iris – the eyes equivalent of the aperture, is constantly adjusting itself to optimally expose the object that has caught your interest (the current subject). As you’re looking around, your eye’s irises are adjusting to optimally expose objects that catch your interest. The dynamic adjusting of the dynamic range of your eyes means everything that catches your focus is recorded with the equivalent of a good exposure setting.
These continual focal adjustments are why your eyes see an event differently than your camera does. Your eyes are actually seeing the event over a period of time. Your eyes are literally sending thousands of images to the brain to render a composite – and thorough – original image of the original event in the mind’s eye. In effect, unlike the fixed dynamic range of the camera your human eye is dynamically making ongoing dynamic range adjustments to see everything clearly.
Perfect Exposure for a Superior Photo means optimal light intensity, or, in other words, optimal exposure, in each and every pixel. A Perfect Exposure photo correction requires:
optimally increasing the light intensity in every pixel in a manner consistent with the physics principles of how the human eye gathers light so all color attributes are responding to the natural attributes of increasing light, and
preservation of Real Color, the original hue of all of the colors in the photo with a patented approach to the RGB Triplet, which will best match the colors of the original event.
To achieve these two principles requires an emulation in your photos of the essential and correct missing eye function your camera lacks.
What if you had a lens emulated at every pixel as Perfectly Clear does as shown in this figure?
“This is the patented solution for optimum light gathering” This patented innovation of emulating a lens at every pixel is an enabler for the solution to analyze light at the pixel level and is a critical piece of Perfectly Clear’s Perfect Exposure. What magic is the solution doing at the pixel level? It’s achieving the two key components necessary to meet the two objectives set out above. Firstly, it’s maintaining the original hue of the color on a pixel by pixel basis. That is, it’s maintaining the hue of each pixel’s location within the CIE color space, by applying a patented RGB Triplet innovation. This is an integral aspect of accurate color and is covered fully in the section on Real Color. Secondly, it’s addressing the challenge of how color is affected as more light is gathered. Fundamentally how light is added to a photo, and the impact it has on color is the single most important issue in photography. To get the accurate outcome Perfectly Clear is modeling the logarithmic function of how the eye gathers light on a pixel by pixel basis, the whole time adhering to the physics principles of incoherent light. Taken together, these produce optimal lighting in every pixel.
The result is a high degree of Photo Accuracy so that your photos are beautiful and match the original image in the mind’s eye. These have been found to be the best memory triggers of the original Precious Memory. Taken together these actions effectively reproduce in your photos the essential and correct missing eye functions your camera lacks. A Superior Photo has the greatest emotional impact on the viewer.
What Others Do
The common “enhancement” methodologies for addressing exposure/brightness challenges of adding white, changing Luminance, dodging and burning, and memory colors results in clipping, arbitrary color shifts, washed out photos and distortions. This example shows the original corrected with a Luminance correction (notice how it’s washed out) and then with Perfectly Clear bringing out the vivid colors with proper exposure.
Some systems resort to memory colors to overcome these obvious shortcomings, but even the software database containing these memory colors frequently fails. This is ironic because they’re supposed to create blue skies and green foliage regardless of the exact hue in the original scene. However, memory colors often turn the blue sky to grey and the underexposed blue water to grey, whereas Perfectly Clear will maintained the vividness of the blue sky and water. In the example below notice how Perfectly Clear brings out the blue water and whites in the sails and sailboat as they appeared that day whereas the memory approach keeps everything very dull and grey.
A further challenge with memory colors and fuzzy logic is that, although they’re supposed to be like “paint by numbers “, they often don’t get the numbers correct! You’ll note below how, in an attempt to turn the sky to a darker blue, a large portion of the sky is missed close to the house and the leaves. This creates a glowing “transition zone.”
These distortions occur because these other methods either don’t model any eye function or, if they do, they model the wrong eye function. Learn more about how todays editing and “enhancement” software takes your Camera’s Distortions and adds “Enhancement” Software Distortions.
Other”Enhancement” methods of increasing brightness distort colors: How does a Perfect Exposure correction measure up?
Perfectly Clear overcomes your camera’s limitation of poor exposure and lighting in your photos, a very common problem of digital cameras. Unlike other photo “enhancements”, the Perfectly Clear correction operates to add light in a natural manner consistent with how the human eye gathers light. This is achieved with a series of algorithms that replace the essential missing eye function the camera lacks. The results are Accurate Photos that match the original image in the mind’s eye and serve to preserve Precious Memories perfectly. Accurate Photos are Superior Photos and science shows superior photos have the greatest emotional impact with viewers.
