I know a lot of people wants to learn to improve the quality of their photos so here's a little guide to help you out!
1. The cameraOf course, the better camera the better pics. BUT if you don't have a fancy system camera, don't worry! Even a cellphone can be used to take very decent pictures if you know how to use it!
2. LightThis is the most important part when it comes to photography and it's also here that most people makes their mistakes. People tend to believe that it's all about the camera. But the thing is the proper lightning can turn even the crappiest cellphone photo to a
portrait! I promise!
Move your photo scene away from the mirror in the dark hallway you will see a dramatic improvement in your pictures quality. Indoor pictures are tricky in general if you don't have a good camera so i suggest you move your scene outside to the daylight. Maybe you have a balcony that can work out for you.
3. Self-timerTake an outfit picture into your mirror is a very difficult thing to success with but sometimes your arm just ain't enough to catch the whole you in one picture. Most cameras (even cellphones) have a self timer. Find it and be best friends! You will have approx 10 seconds to get yourself in the right position. This might require a bit of patience since you sometimes have to take many pictures before you get it right.
4. Be STILLThis is also a very important tips that many people forget. If you don't have an awesome camera your camera most likely will take dizzy pictures when you move. So the more still you are the sharper will the picture be. With daylight your picture can be knife sharp even with a low quality camera. If you are taking pictures of your face still use the self timer. That way the camera will be perfectly still. It's difficult to hold the camera still with your own arms but if you must use it take support to a shelf of something nearby so the camera don't hang in the air, that way it's easier to keep it still.
5. Let the camera do the jobCameras are great, they have a lot of options for you to choose between. Try them out. The camera often "senses" the light in the room, when preparing the camera for a self-timer don't be in too much hurry to press the button, give the camera some seconds to adjust to the surrounding. If you are taking a picture where you are standing several steps away from the camera don't stand in front of the lens while pushing the self-timer button, this sometimes confuses the camera and makes it believe you are suppose to stand close so the focus turns out all wrong.
6. Close-upMost cameras and cellphone have a close up option called Macro. On both my camera and my cellphone it looks like a flower. It's important to use this if you take a photo of something close for example a flower, and earring that you want to show. Or else the camera will focus on your background and you item will become a dizzy spot. This option can be tricky to handle it varies from camera to camera so you have to try it out. This option is really easy on my cellphone but very difficult on my camera, i still haven't quite got it right yet.
Also remember that the macro option sometimes is extremely sensitive. Since it focus so much even the tiniest movement will affect the picture and make it dizzy. So if you don't use the self timer take support from the interior (note that if using the self timer be sure to not move the camera when pressing the button). Hold the camera against the back of a chair, a table, a shelf or anything suitably.
7. Think outside the box!And here comes the fun part! Sometimes it's very hard to get a good angle. Sometime you want an angel from down below and another time from an angel from up above. Try it! Cameras can be very hard to put in a angeled position. I use a lot of tools to solve these troubles. Use you imagination!
I use shelves and books piled on each other to get the right height on the camera. I use a vase where the camera can point a little lower or a little upper than straight ahead. I have even used tape an taped my camera into a vase to take a picture from up above when i was laying on the
floor in the shot. Sometimes i use a little coin just to adjust the angle a little bit. Sometimes I'm standing on a
stool. Ask yourself: What do I want to highlight? Maybe the skirt - place the camera in skirt height. Maybe your face - place the camera in face height. Maybe your jewelry - place the camera in chest heigt or a little above, maybe with a slightly looking down angle.
When I'm outside in the nature i carry with me my vase. That will make my camera stay steady so it wont fall and break. I use big stones, walls, bridge railings, trashcans and stairways that I can find to lift my camera of the ground. Take advantage of hills and valleys!
7. Still can't get focus all over the picture?Clean the lens! Most of the times when i have an unsharp area on my pics it's because the lens have gotten dirty ^^'
