In this presentation, I will review the basic camera functions, so have a seat, bring a hot cup of coffee with you and enjoy the journey! If you are not keen on reading, you can also listen to the presentation with the sound bottom in every page. At the end of the presentation, all the quotations of the information and images I used will be shown.

S mall, Medium, or Large JPEG ?

Small JPEG files let you capture a lot more images on your memory card and they also process faster big JPEGs have better quality.

RAW Files

T he purest form of digital capture O nly one size A bigger record of the data captured by the sensor C apable of preserving all the original image information M ore flexibility during postproduction by allowing for the creation of higher quality images Contain two different kinds of information: the image pixels and their metadata, which are tiny bits of digital information on file format, exposure adjustments, and color balance.

White Balance

RAW CONVERTERS Use to find proper colors White balance: removes unrealistic colors from photographs. Find the WB function or auto white balance (AWB).

P rime lens or zoom lens?

P rime lens is your standard normal lens that provides a fixed focal length A zoom lens offers a range of focal lengths.

Not interchangeable Usually offer better optical quality with wider maximum aperture It’s lighter and smaller As you cannot zoom, you will have to move physically closer to your subject to get that up-close shot.

Zoom L ens

Broad range of angles and magnification options Zooming in on a subject allows you to tighten your framing to make the scene bigger, with less visible background. Zooming out, on the other hand, loosens the frame so the subject appears smaller and further away, giving you more background.

Caution !

Before you remove your lens, read the user manual to ensure you are handling the functions of your specific model correctly. The lens is one of the most valuable parts of the digital camera and can be very expensive to repair and replace.

Autofocus: Just press the shutter button (or power button) halfway down to see the focused subject. You will see the image come into focus and there will be some sort of status indicator in the viewfinder or on the LCD screen when the focus “catches” on the right setting.

Manual focus: Can improve your photographic technique The process is a bit slower than AF, but it will work in any situation regardless of lighting.

Seems difficult, right? Don’t worry, just keep shooting, no matter what! Take a break if you want, when you ready, click next and continue exploring photography!

Angle of View

The view provided by a lens, whatever it sees and captures, relates to the process of magnification. Short-focal-length lenses have a wide angle of view, so subjects appear further away. Long-focal-length lenses have a narrow angle vantage point, which magnifies objects and makes them look bigger and closer. This perspective and overall magnification of a given focal length is directly related to the size of the camera’s image sensor.

Depth of Field

For maximum depth of field, you can set a small lens aperture and focus on a subject that’s not too close. If you want to get creative with focus and use it selectively to highlight expression or effect, you would set a wide lens aperture and focus at a close distance

Scene 25 (15m 2s)

Controlling Light

It is central to the process of photography. A light meter measures the illumination around the subject and suggests a combination of f-stop and shutter speed to produce the right exposure for the ISO you’ve set.


Scene 26 (15m 34s)

Full automatic (AUTO, A)

This mode allows the camera to choose Useful any time you just want to focus and take a picture. Minimum experience needed!

Scene 27 (16m 3s)

Program Autoexposure (P)

This lets the camera set up everything but ISO, white balance, and flash functions. This allows you to still point, compose, and shoot—but you have more control over the visual elements in your pictures because this mode gives you the option to set exposure to tweak depth of field or freeze motion.

Scene 28 (16m 39s)

Subject-program Autoexposure

In this you choose the setting, such as portrait, landscape scenes, sports, etc., and the camera chooses the right exposure for whatever subject you select. But if you want your portrait subject to have more depth of field that normally found in that mode, you will need do it yourself.

Scene 29 (17m 14s)

6 tips para que tu café de la mañana sea aún más saludable

Aperture Priority Autoexposure (A or Av)

This lets you choose the f-stop, and the camera selects the corresponding shutter speed. This provides the advantage of autoexposure functions, which are simple and spontaneous, while also controlling depth of field and low-light scenarios.

Scene 30 (17m 47s)

El café de variedad es el mejor para los deportistas -

Shutter-priority Autoexposure (S, T, or Tv )

With this you choose the shutter speed, and the camera selects the corresponding f-stop. Helpful if you are concerned about holding the camera still enough to take a good picture and set the shutter speed faster to avoid shaking—the camera will adjust the f-stop according to your selection.

Scene 31 (18m 21s)

Manual Exposure

This means you set both the f-stop and the shutter speed all by yourself, guided by the handy light meter reading, of course. As you select different combinations, you will see a display in the viewfinder or LCD to help you find the proper exposure. Use this when you want to go full-expert and need total control over f-stop, shutter control, and your overall exposure, including depth of field and motion. You are in charge, not the camera! This option offers maximum flexibility and control over the final results.

Scene 32 (19m 20s)

Flash Functions

O ffers a “flash” of light from the camera at the exact moment the shutter button depresses and a picture is taken, thereby giving a dimly-lit scene that extra bit of needed exposure. C an also be used to freeze the motion of active subjects, as well as brightening up dark, shadowy areas from harsh, direct, or inadequate lighting.

Red Eye Alert!

H appens when a flash fires at a pupil that is dilated in low lighting. C an be avoided by using your camera’s red-eye-reduction setting, which causes the camera to fire a few short bursts of light before the picture snaps. As a result, the eyes of your subject respond to the light and fail to dilate, so there’s no weird redness. I t is also possible to retouch red-eye images after the fact by using an image-editing program.

A person’s eyes are the only thing visible in the image with a bright red cast to the pupil as the eye picks up the flash.

That's all for today!

Thanks for watching! I hope you didn’t overwhelmed with the information so much, photography seems difficult but once you are experimenting, you will have hours of fun for sure!
