Print Resolution for Photographs
Generally, images should be at least 300 dpi/ppi at the dimensions you plan to use the photograph. For example, if a photograph is intended to be printed at 5鈥 x 7鈥 in your final printed piece, it should be at least 300 dpi/ppi when at those dimensions.

The best way to keep improving is to practice often, make mistakes and be open to learning from others, whether they鈥檙e well-established photographers or newcomers to the craft.
Understand the rule of thirds
The rule of thirds is based on the idea that pictures are generally more interesting and well balanced when they aren鈥檛 centered. Imagine a grid placed over your images with two vertical lines and two horizontal lines that divide the picture into nine equal sections.
If you were following the rule of thirds, rather than positioning your subject or the important elements of a scene at the center of the photo, you鈥檇 place them along one of the four lines, or at the points where the lines intersect. Some cameras even have a grid option you can turn on, which can be useful if you鈥檙e still learning to compose your images.
Eyes should always be in focus
When shooting portraits, you鈥檒l be focusing on a very small area so it will be more important than ever that you get a nice sharp image. The eyes in particular are an important facial feature, and they鈥檙e often the first thing people look at, especially when it comes to close-ups and headshots.
With this in mind, your subject鈥檚 eyes should be your main point of focus.
Pay attention to the background
Generally speaking, the background should be as simple and clutter free as possible so that it doesn鈥檛 pull the viewer鈥檚 attention away from the main subject of the photo. Muted colors and plain patterns tend to work well, because you don鈥檛 want viewers to end up being more interested in the colorful building or church tower in the background than your model.
Fixing a distracting background can be as simple as moving your subject or changing your angle, but if that doesn鈥檛 work, it may be possible to obscure it by using a wider aperture and getting in as close to your subject as possible. Whenever you can, though, try to keep the background neutral, especially if you鈥檙e placing your subject off to the side of the photograph and the background is very visible.
Understand the exposure triangle
The exposure triangle simply refers to the three most important elements of exposure; ISO, aperture and shutter speed.
ISO
ISO controls the camera鈥檚 sensitivity to light. A low ISO setting means the camera will be less sensitive to light, while a higher ISO means it will be more sensitive to light..
Aperture
Aperture is the opening in your lens and controls how much light gets through to the camera鈥檚 sensor as well as the depth of field. Depth of field refers to the area surrounding the focal point of the image which remains sharp. A larger aperture (indicated by a lower f-number) lets more light through, but has a shallow depth of field. While a smaller aperture (indicated by a higher f-number) lets less light through, but has a deeper depth of field.
Large aperture is best for portraits
When shooting portraits, whether of people or animals, your subject should be the main focus of the picture and the best way to achieve this is to use a larger aperture. This will keep your subject sharp, while blurring out any distractions in the background.
Small aperture is best for landscapes
Landscape photographs require a different approach, because everything from the rocks in the foreground to the mountains in the background should be sharply in focus.
A larger f/ number means a smaller aperture, so go towards f/22 or higher, depending on what your lens allows.
Learn to use Aperture Priority and Shutter Priority modes
If you want to venture out of automatic mode but don鈥檛 feel confident enough to switch to manual yet, Aperture Priority Mode (A or Av) and Shutter Priority Mode (S or Tv) are two very useful options that are available on most cameras and will give you more control without being overly complicated.聽聽
Aperture Priority Mode lets you select the aperture you wish to use and then the camera adjusts the shutter speed accordingly.
In Shutter Priority Mode, you select the shutter speed you want to use and the camera will select the aperture for you.
Shutter speed
Shutter speed controls how long the shutter stays open when you take a picture. The longer the shutter stays open, the more light gets through to the camera鈥檚 sensor. A fast shutter speed is good for freezing action, while a longer shutter speed will blur motion. Long shutter speeds can give interesting effects, but usually require a tripod.
Make a habit of checking the ISO before you start shooting
Discovering that you鈥檝e accidentally shot a whole series of images in ISO 800 on a bright sunny day can be extremely frustrating, especially if the photos were taken to document a special occasion such as a birthday, anniversary or other event that can鈥檛 be recreated.
It鈥檚 an easy enough mistake to make, though, so to avoid this unpleasant surprise, make a habit of checking and resetting your ISO settings before you start shooting anything. Alternatively, make a habit of resetting this every time you鈥檙e ready to put your camera back in its bag.
Be careful with your on-camera flash
If you鈥檙e not careful, using your camera鈥檚 built-in flash at night or in low light can lead to some unpleasant effects like red eyes and harsh shadows. In general, it鈥檚 better to crank up the ISO and get noisier photos than to use the on-camera flash and risk ruining the shot altogether.
Invest in a tripod
If you want to get sharp photos in low light without raising the ISO too much, a tripod is an essential accessory. It will also allow you to experiment with long exposure photography, where you leave the shutter open for seconds or even minutes at a time, which can make for some amazing effects when photographing things like cityscapes or rivers and waterfalls.
Shoot in the early morning and evening
Lighting can make or break a photo, and the early morning and evening are widely thought to be the best times of day for taking photos. In photography, the hour just after the sun rises or before it sets is called the 鈥済olden hour,鈥 because the sun is lower in the sky and the light is softer and warmer.
Whether you鈥檙e shooting landscapes, portraits or still life, using the early morning or evening light can give your photos a serene feel with its warm glow and the long shadows it casts. Of course, the golden hour is not the only time you can get good outdoor photos, but it does make it easier.
Learn from your mistakes
Getting overexposed, blurry or badly composed photos can be frustrating, but rather than letting such photos discourage you, use them as a learning tool. The next time you get a bad photo; don鈥檛 immediately hit the delete button. Instead, spend some time studying the photo to work out what went wrong and how you could improve it.
