The Basic of Exposure by rick gondrong

Making a good photo require us to pay attention to the exposure of the photo. Camera have to ascertain the amount of optimal light to the camera censor to create a good color tones of the photo. This matter is obtainable by arrange long exposure (shutter speed) and light intensity of lens (lens aperture). All digital camera at this time have arranged the exposure automatically. But its still need the human to readjust the exposure to get desire photo.

Extremely Illumination
At the extremely level of light brightness is not possible to get the right exposure which recording the detail of shadow without light excess at point of interest the object. Or the otherwise. Generally the camera own the dynamic range value about 4EV. Its meaning we still can see the detail of shadow which is 2EV darker than mid tone of photo. And otherwise, 2EV lighter than mid tone of photo.

Mid-Tone
The concept of the mid-tone is a tone or detail at the middle area of the object photos. Mid-Tone is representing the parts of picture that we want as a point of interest at the photo. To maximize the exposure, the camera work at the standard of grey color tone, precisely its 18% grey. Thereby, we shall arrange the object at this level of brightness. This is one of weakness metering from all camera.

Metering
Light Metering on camera cannot differentiate the object which owning a different inheren brightness level. But, the camera at least can catch the contrast of illumination. By default, the metering system of the camera is Multi Pattern, which is measuring light brightness value of the object. With multi pattern metering, the camera automatically can accomodate a type of light which is captured from the object.
But all photographers most prefer to use the center weighted metering, that is emphasize the light measurement at the middle of the frame. While a spot metering, also emphasize the light at the middle of the photo which is centralize at the smaller area.

Aperture And Shutter speed
The camera arrange the exposure by using shutter speed and lens aperture. The combination among shutter speed and lens aperture can give various creativity in photography. The smaller aperture, earn the compensation with the slow speed of a shutter speed. Otherwise, by boosting up the speed of shutter speed, will need a larger lens aperture.

Simple mystical effect on your photo by rick gondrong

Step 1.
Fix your original photo histogram by using image adjustment level and curve

Step 2.
Use Unsharp Mask tools to more sharpen your photo, if your photo not to sharp.
In this photo, i used the amount 100 and radius 1px

Step 3.
Create duplicate layer from background and rename as cloud, then use filter-render-clouds to create smoke effect to the photo

Step 4.
Coloring the smoke with yellow to give warm effect to the smoke, I used color balance on image adjustment on this step

Step 5.
Change the Cloud layer Opacity to 81% and Fill to 51%

Step 6.
Use your creativity in deleting some smoke area on your photo

Step 7.
Create enother duplicate layer from background and name it Blur. Then use filter-blur-gaussian blur with 50px

Step 8.
Change the blending option of Blur layer to Hard light. This will give more contrast light to your photo

Finish
