Will you improve your photography by taking an online photography course? The answer to this is yes, if you are serious about photography and keen to learn all aspects of the trade. But the first thing that you have to do is pick a course that will suit your spare time and your budget.
Techniques - When photographing prepared food, you have very little working time before the food starts becoming visually un-appealing, so everything must be planned and staged ahead of the actual shoot. You have to work fast and get close. I like to visualize the setting and draw it out beforehand on a piece of paper. That way I can have the background and props already in place when the plate of food arrives, so I can squeeze out more working time.
Think small. Macro photography will change the way you think about your photos. The small, intricate, and interesting details of the things of nature will open up a new world to you. Take pictures of flowers or the insides of flowers, bugs, or even the parts of a bicycle. The only limitation here is your imagination. Turn it loose and amaze your audience with the new creative you.
Standard zoom lens normally have a focal length between 18mm to 55mm or slightly more. Such lens is commonly offered as kit-lens and is a good lens to get started with for beginners. This wide range of focal lengths are most suitable for landscapes and portraits.
Key to street photography is focusing, not only sharpness but depth of focus or depth of field. More than other types of photography, excluding landscape, you need as much of the image in focus. Not so for individual objects but rather for street scenes. Set you aperture to f11 or smaller and manually focus if necessary. The great thing about street photography is reviewing your images later and finding little scenes within scenes. If you have a good enough depth of focus you'll find many smaller objects you hadn't noticed while shooting.
Wedding photographers - Those people you see running around at weddings may not look much but taking pictures photographer at weddings can be difficult work. The photographic style must match the theme of the wedding and the photographer should know what highlights of the event to take pictures of.
If you are considering landscape photography as a career (even part time), the first thing you are going to want to do is learn as much about it as possible; read books, take classes, visit websites. Then you are going to want to practice, and build a portfolio. Your portfolio should be updated often and only include your absolute best work. You may want to send some of your best photos to photo contests or magazines. These are good ways of breaking into the world of professional photography when you have no experience.
