How does a camera work?

Most of the times when we buy a camera look over the manual to see how the most common things we do. When we have questions we seek to address it manually but it seems boring to read the full manual. Personally I think it is wise to go slowly reading the manual, better knowing the camera operating will better for good photography.

In this article we will explain some of the things learned while taking pictures. For example, look at nighttime view, is simple to perform but probably not consult the manual if your camera does not find the appropriate option. In unit 14 we explain how to make pictures like this…

Definition

A camera is a device (a machine) capable of capturing light on a stand.

The camera is just the tool that allows us to take pictures. But there are two ways that people get closer to the cameras, so some are a complicated and heavy instrument that just want to know what is necessary to take a picture, while for others it is a jewel of engineering, machine required and would like to buy the model that just came out and making a new fancy stuff, something very important to justify the outlay, even though deep down we know we could wait a while to come down in price.

What you can do with the Photoshop

Fix the frame.

When taking a picture you may not have the ability to perform proper activation frame for various reasons, for example, in the picture of the head of the turtle did not suit closer to avoid frighten the bird and window frames appear. With Photoshop we can vary the framing and expand the image a bit to make it more to our liking. 

 

Remove items

In this photo we see the lamp and the wires do not add anything to the picture, if we want to eliminate can do with Photoshop in a few steps.

Lighten dark image

This photo taken on a photo and backlit inside has been very dark and we had no more time to do more photos, instead of discarding can retouch with Photoshop. With a few simple tinkering is as you can see by clicking on the image.

• Retouching

You can retouch an image to a slim figure, the following example is a case a little exaggerated but the technique can be applied more realistically. Click on image to see the slimmed figure. In item 22 we will see how.

To make these improvements with Photoshop is useful to know some technical concepts of photography that will go explaining along the way.
