synopsis

It was very interesting i learned a lot and was cool to watch them work within a time limit and see how quick they can get a good shot. The way they told there model or the action actor to move around and get them to do what they want and see how the pictures come out is really cool and was very interesting to watch.

File format

JPEG: This is probably the best known of all image file formats, and what the majority of digital cameras provide as a digital output from a camera. 

TIFF: This is the most used industry-standard file format and is generally what print or publishers ask for. 

RAW: RAW files are generally available on advanced compact cameras and DSLRs and quite simply put; it is the best option if you want to get the absolute best file from your camera – this is the option preferred by professional photographers. 

DNG: Just about every camera these days uses a different proprietary format to capture raw files. 

PNG: Designed in the 90s as an improvement for GIF file format, PNG files are ideal for use on the internet. 

GIF: Like PNGs, GIF files are ideal for use on the internet. Lossless compression means image quality is not sacrificed, and like PNGs they also offer the ability to maintain transparency (but can’t support partial transparency) and also allow for animation. 

BMP:  Another lossless file format, BMP was invented by Microsoft, initially for use on the Windows platform but is now recognized by programs on Macs as well. 

PSD: This file type is what Adobe Photoshop uses as a default to save data. The big advantage of PSD files are that it allows for manipulation on specific individual layers, rather than on the main image itself. 

camera modes

 Automatic- 

I suspect no one will need any introduction to this mode (as it seems most digital camera owners use it). Auto mode tells your camera to use it’s best judgement to select shutter speed, aperture, ISO, white balance, focus and flash to take the best shot that it can. 

Portrait mode- 

Portrait mode When you switch to portrait mode your camera will automatically select a large aperture (small number) which helps to keep your background out of focus (ie it sets a narrow depth of field – ensuring your subject is the only thing in focus and is therefore the centre of attention in the shot). 

Macro mode- 

Macro mode lets you move your closer into your subject to take a close-up picture. It’s great for shooting flowers, insects or other small objects. Different digital cameras will have macro modes with different capabilities including different focusing distances. 

Landscape mode- 

his mode is almost the exact opposite of portrait mode in that it sets the camera up with a small aperture (large number) to make sure as much of the scene you’re photographing will be in focus as possible. It’s therefore ideal for capturing shots of wide scenes, particularly those with points of interest at different distances from the camera. 

Sport mode- 

Photographing moving objects is what sports mode (also called ‘action mode’ in some cameras) is designed for. It is ideal for photographing any moving objects including people playing sports, pets, cars, wildlife etc. 

Night mode- 

This is a fun mode to play around with and can create some wonderfully colorful and interesting shots. Night mode (a technique also called ‘slow shutter sync’) is for shooting in low light situations and sets your camera to use a longer shutter speed to help capture details of the background but it also fires off a flash to illuminate the foreground. 

Movie mode- 

This mode extends your digital camera from just capturing still images to capturing moving ones. Most new digital cameras these days come with a movie mode that records both video but also sound. 

20 important facts

1.All DSLR systems offer a dizzying selection of lenses for their cameras 

2.they range from fisheyes that give you 180 field of view  

3.or telephoto lenses up to 800mm or more. 

4.when buying your first lens you can be wrong about one  

5.figure out what you want to shoot  

6.then find your budget 

7.less expensive lenses will generally have variable apertures, meaning as you zoom 

8.more expensive lenses have a fixed aperture. 

9.all manufacturers offer a variety of focal lengths to satisfy most budget. 

10.standard lenses range from about 35mm to about 85mm 

11.lenses in the standard zoom range will cover moderate wide angles-typically 24mm to 35mm 

12.moderate lenses are great “walk around “lenses they are versatile, allowing both for wide angle work such as landscape 

13.or zooming in to the telephoto end of the lens to take a great portrait 

14.standard zoom are generally included in many SLR kits that come with lenses. 

15.18-55mm 

16.18-135m 

17.24-105mm 

18.24-70mm are all popular standard zooms 

19.prime lenses are lenses that are just one focal legth. 

20.the most popular seem to be various flavors of 70-300mm or 70-200mm. 

Depth of Field explained

When a photographer is talking about “depth of field” in an image, they’re referring to how much of the picture they choose to have in focus. It can take your focus from anything with “depth of field” and make your attention go wherever the focus is. Depth of field is controlled by changing the aperture on you camera. Like your eye, a camera lens has an iris inside that can open or close to let in more light or less light. You control the size of this hole, or aperture, by changing the aperture setting, which is measured using a scale of f-stops. 

To change your aperture, you must have a camera with an aperture, you must have a camera with an aperture priority or manual mode. On most cameras, aperture priority mode is indicated on the mode selector by an A, through canon cameras use AV. When in aperture priority mode, you choose the aperture you want, and the camera automatically picks a corresponding shutter speed to yield a good exposure. For details on changing modes and using the aperture priority mode, consult your camera’s manual.
