Analysis of the new PS to fog mirror function

Fog Mirror function detailed comprehensive based on Raw files

Adobe upgraded all of its products to CC 2015 this month, and the new version of Photoshop is optimized for system operations, but the new camera Raw 9.1 Adds a very practical fog-going function. In the last few days, Beijing again ushered in a continuous heavy pollution haze days, we will look at Adobe's fog mirror function of how practical, the current domestic software fog mirror function compared to what is different, the actual use of fog mirror function is easy to be replaced by conventional adjustment.

• Based on raw more effective? PS to Fog mirror test

First, let's take a look at Adobe's vigorous launch of the camera raw fog mirror function. The Photoshop update from 2014 to 2015, in the functional and not much progress, the main upgrade from Camera Raw 9.1, that is, the new camera raw memorial. Fog mirror function is a domestic software more common functions, but also very practical function, we first look at this based on the raw file to fog, the effect of how.

Photoshop 2015 fog mirror function in camera Raw 9.1, the specific operation will be introduced later

Before using the fog mirror, we must first distinguish a misunderstanding. Fog mirrors are not designed simply to eliminate mist or haze, and when filmed in an opaque environment, photographs can have a "foggy" effect, using a fog mirror to make the picture more transparent, rather than removing the mist and haze from the screen. So the fog mirror is more likely to be used in cloudy, or direct sunlight is strongly caused by the image of the gray scene.

Fog Mirror Example: the air permeability is not enough to fog, the effect is obvious

By contrast, the fog mirror in dealing with the problem caused by light problems, the effect is still very obvious, especially for the enhancement of color richness and photo-level sense. After using the fog mirror, the photo will appear sharper, clearer and more colourful. From the actual use, the fog mirror is not alone equivalent to sharpening and enhance contrast, all aspects of treatment is good. Because the fog mirror has a good effect on the clouds, let's take a look at the contrast effect.

Example: To improve cloud level, the effect is good but color change

For the adjustment of the Clouds, Adobe's fog mirror performance is also good, because based on raw files, so there is a color offset is not a problem, can be easily corrected. Let's take a look at everyone in the Royal Park this kind of air dirty environment, to fog mirror is still useful.

Example of fog-mist: effects on haze, elevation contrast

As has been said before, fog mirror in the haze days of the role is not large, or accurate, to fog mirror can make the picture more colorful, but for its own no color haze weather, fog mirror function is limited. In foggy weather, Adobe's fog mirror to enhance the contrast is still very obvious, in the fog fog can enhance the details of the performance, but also to improve the level, but to rely on the fog to completely eliminate haze, basically is not feasible.

Function Summary: Fog mirror can improve contrast, enhance color, enhance the level, improve sharpness, the function is not simple to enhance contrast or sharpening, with other later software adjustment, can quickly improve the picture hair ash problem, but can not remove haze from the essence.

• Different software contrast algorithms vary greatly

Below we compare camera RAW file based on the fog algorithm, and the domestic based on JPG software algorithm what difference. Here we choose the domestic software for everyone familiar with the lighting magic hand, this software is very mature a lightweight image processing software, in the country has a high visibility and utilization rate.

This time we contrast, is the domestic traditional image software: Light and Shadow Magic hand

First, let's take a look at the fog-adjusting function in camera Raw 9.1. The new PS CC 2015 's fog mirror function hides in the camera raw effect one column, with a 100 to +100 adjustment range, which can be adjusted parameters, and the latest lighting magic hand adjustment filter is more like the United States Mito (I do not like this form), fog is a simple filter, There is no tuning option.
