Couple Poses For Photography - Which Poses Work the Best?

!±8± Couple Poses For Photography - Which Poses Work the Best?

If you do a lot of work with couples who want to get flattering portraits of themselves, then once in a while you might run out of ideas for poses. Here's many ways to take casual, romantic, or simply unique photos of the couple.

Before you think about the poses, you should also put some thought into things like how to bring out their unique personalities and how to depict the nature of the relationship between them. Depending on preference, the portrait might be taken in your studio, outdoors such as a garden or park, or at a location with a special importance to the couple. You could ask the couple to bring personal props to use for this purpose.

Here's the list of great pose ideas. Take away what you think might work well for the shoot.

1. Classic shot - either one sitting and the partner stands behind them with a hand on their shoulder.
2. Close up of the woman resting her head on the man's shoulder or chest, or simply having their arms around each other.
3. Close up of the two of them looking into each other's eyes. This is a profile shot with their heads turned to face each other.
4. A more romantic one - the man giving a light kiss on her forehead, cheek or even her neck, while she closes her eyes and smiles softly. This can be done from the front or as a profile shot.
5. Instead of the usual shots, the couple could be laughing or smiling at each other, instead of the camera-ready smile. To achieve this, it's great to have the couple simply talking with each other, while ignoring the camera.
6. Action photos also work well. Try some physical, unusual activities - wrestling, running through a field of flowers, chasing each other on the beach, and so on.

Start trying out these shots, and with practice you will soon start to get a hang of it. This is an easy way to learn how to take great portrait photos.

Differences Between Film and Digital

!±8± Differences Between Film and Digital

The modern, film-based single lens reflex (SLR) camera is a complex of electronics, mechanics, and ultra high-precision optics. A major part of its operation is concerned with winding-on and rewinding the film - in the camera illustrated here, a motor performs this function as well as controlling the mirror action. As you would expect, autofocus cameras require a further layer of complicated integration between the electronics, optics, and mechanics.

While a digital camera is no less complicated in its mechanical and optical construction, its electronics are far more powerful than you would find in a film-based model. A major saving is not having to transport the film -the design for a static photosensor is far easier than that for a moving strip of film. But nearly all other film-based camera operations are needed.

Image structure

Film
- silver grains or dye clouds of varying size distributed in a random pattern.
Digital
- same-sized sensor pixels arranged in a regular grid, or raster array.

Colour recording

Film
- colours in the scene separated by red-, green-, and blue-sensitive layers.
Digital
- colours in the scene separated by Bayer pattern of red, blue, and green filters.

Colour reproduction Image amplification

Film
- dye clouds of cyan, magenta, and yellow. Development by chemical action.
Digital
- interpolated from colour filter array. Electronic and digital processes.

Image quality

Film
- depends on film speed, grain structure, and processing regime.
Digital
- depends on sensor resolution and interpolation methods; also compression, if used.

Storage

Film
- image fixed by removing unexposed silver black and white stable, colour less so.
Digital
- image stored temporarily on memory cards or hard-disks.
