Exciting color pictures always have something special that could be mood, pose, action, atmosphere or design.
Color can be any quality-
Hot and heavy, soft and misty, clear and clear, black and mysterious.
The photographer learns how to use his equipment and materials.
It is most important to choose the right movie.
The movie doesn't "see" the color as the human eye does, so there are various types of color films that react to two different kinds of light
Daylight and Labor(
They can be used interchanged with conversion filters in a pinch, but this reduces their speed). Transparencies? Prints? Or both?
A movie with the words "chrome" or "color slide" in the name will produce a color transparent film on the front, which can be projected on the screen or checked in a handheld audience.
Transparent film can be made into print, but this is not their main purpose at present.
There are all kinds of "speed" in color films "(
Sensitivity to light).
In the United States, the speed rating is called the "ASA" value;
Some foreign ratings are called "DIN" values.
The appropriate numbers must always be set to the exposure meter or the built-in exposure control in the camera.
The ASA rating for color transparent film with relatively "slow" advertising may be 25.
It will be useful for bright, sunny, beach or snow scenes, regular outdoor portraits and regular outdoor work, where there are plenty of light ads. Dorothy ·
The "high speed" transparent film is rated from ASA 160 to 500.
Some can be "pushed" higher by special handling.
They are useful for quick action or low light work.
In general, they are rougher than slower films, with lower color fidelity and clarity.
The ASA rating of a "moderately fast" color negative can be 80.
Many simple cameras that do not have a speed setting are designed to use this film in an outdoor or indoor average light condition for optimal results.
Film can also be measured in an adjustable camera.
In addition to Christmas, Easter and birthday parties, color photos taken outdoors in warm weather may be more than any other time.
Sports, travel, picnic, vacation, playground, flowers, pet, rock concert-
All weather events bring a lot of cameras.
People in the processing industry also know that they will bring a lot of mediocre pictures.
What special thing will they become?
First, think about what is shown in the viewfinder and take a few seconds to move the camera or subject to a relationship that looks very good in composition and color combination.
Filling the viewfinder with the main theme is the easiest way to get attention and stay interested.
This may need to change the lens or move the camera closer, or both, but it's worth it.
Close-up movement can usually eliminate interference such as garbage or someone's elbow, and only this item can change the "snapshot" to a photo.
Color creation is a matter of personal taste and style.
A color photo with different saturation can be as eye-catching as a wild rainbow. (
Photos of natural rainbows are spectacular and should never be missed. )
Perfect Exposure usually "makes" a color picture.
Most color films only record the brightness ratio of three to one, so professionals usually put their exposure "stand" up and take some photos while reading the meter, then take a few more photos in a quarter or half a month. Negative film (
For making prints)
There are more degrees of freedom, and it can be corrected more easily when printing.
For pictures with true colors, it is usually recommended for morning and noon advertising time, and side lights with some shadow details are usually more interesting than direct or flat front lighting.
For outdoor portraits, direct sunlight usually narrows the subject's eyes.
People will relax when the sun is used as a background or side light, but will be in the shade.
By using a blue flash or an electronic flash as a fill light in a shadow, the photographer can balance the light and give the portrait a true professional quality.
Other simple filling tips are to use the reflection of a bright beach or white wall to have someone lift a white sheet or towel and project the sun's light into a shadow on the subject's face.
Sometimes a strong nearby color may be reflected on a light-colored body --
Not noticed in real life, but not popular in photos.
This can be avoided by keeping the distance between a light object and a large number of heavy-colored objects.
The scenic panoramic photos pose the opposite of the portrait.
A large open landscape may be boring if there is nothing strong in the foreground.
It could be a person, a tree, a rock, a castle --
Or anything that can guide the eye into the distance and give it size and grandeur.
Skylight filters with transparent film can reduce atmospheric smoke in the distance and help the scene look more solid.
UV filter can be used for color negative, although it is not needed.
From the early morning fog to the glorious sunset, from the night mode of traffic to carnival lights or window displays, eye-catching color photos can be taken outdoors at almost any time.
The time exposure of moving lights at night is impressive, as are the reflected lights on wet streets.
Flash is also a useful device, but it is not always the answer to every prayer.
When people use their small units at large parties and find most of the pictures in the dark, they tend to be disappointed.
These units are not too far away, so it is important to understand the scope of each unit and follow the recommended guide number.
Indoor photos can be taken in daylight close to the window and filled with a flash or taken separately with a flash.
The indoor flash in the evening is best shot in a room with moderate wall light and low ceiling color.
Movies and pictures can both deteriorate or fade if stored improperly.
They should be kept away from the heat and humidity and not stored near the radiator or in hot car suitcases and glove compartments.
If the film is sealed and kept in a refrigerator or freezer, they will remain at a long speed, but must return to room temperature before use.
The exposed film should be processed as soon as possible so that the potential image will not deteriorate.
Advertising color pictures on the display should prevent high temperature or strong light exposure to keep fading to a minimum.
It would be helpful to shine them with UV glass.
