Image quality improvement with high speed canon 80D for film
While technically a megapixel (MP) is equal to 1,048,576 pixels, in reality, camera manufacturers round this number to 1,000,000 when stating how large an image the camera will capture.
All you really need to know is that the higher the megapixel count, the more data the photograph will contain, (e.g. a 21 MP camera can shoot more detail than a 14 MP camera with best slow motion camera .
Choose the largest image size available (e.g. ‘super fine’) to get the maximum number of pixels. The higher the resolution, the better. You can always reduce the image size later, say, if you need to email the picture, or upload it to an on-line album. But you can never increase the image resolution without deterioration in quality.
When it comes to displaying images on a computer screen you need far less pixels than you do for printing. This is because the density of pixels on the screen is far less than what is required for printing. For example, a typical monitor is 1920 x 1080 pixels in size.
1. JPEG (Joint Photographers Expert Group)
When you set your camera to shoot JPEG files, an algorithm determines which information is discarded and which is kept, without changing the way the image looks. This is great for saving space on your memory card, but not so good if you intend to edit in Photoshop. However, here are the benefits of shooting JPEGs:
If you do not wish to spend time editing your photos.
If you want to save space on your memory card, (e.g. when travelling).
If you want to shoot super-fast in continuous bursts and best lenses for canon 80D
This is the native, uncompressed digital camera file, offered on higher-end cameras. Admittedly, there are disadvantages of shooting in RAW format. Firstly, your image files will be about five times bigger; secondly, you will need more storage space on a computer; and finally, it may impact your editing workflow, slowing you down.
The overwhelming advantage of shooting in RAW format is that you do not discard any data. You can use this information to create the best possible image. For example, this flexibility means you could recover blown-out highlights or bring back detail in the shadows that would be impossible to do with JPEGs. Think of a RAW file as being akin to a film negative which you can process how you want – in a ‘digital darkroom.’
With landscape photography, you will usually want everything tack-sharp, from foreground to background. If your camera has Aperture Priority (A, or AV), use it. Take control of the depth of field (how much of the scene is in focus) by setting the camera to a small aperture between f/n and f/22.
Also, deliberately focus about one third of the distance into the scene. This is called the hyper-focal distance, and should ensure all elements in your photograph are sharp.
There are four main focus modes, depending on your camera model. They are Continuous, Single, Automatic and Manual. Here is a brief overview of when to use each focus mode.
• Continuous Focus / Al Servo – for shooting quick bursts. Mainly used in sports, wildlife and action photography when the subject is moving quickly.
• Spot Focus – In this mode, when you depress the shutter button halfway, the camera focuses on the
subject just once – there’s no continuous adjustment. This mode saves battery power, and is ideal for portraits or static landscapes. Automatic Focus / AF – Some cameras do it all for you.
Manual Focus – In low-light situations, the camera’s auto-focus system will not work. On a DSLR camera, switch the focus button on the lens to manual, and turn the focus ring.
A traditional camera has an optical viewfinder which the photographer looks through.
Modern digital cameras all sport LCD screens. However, only the more expensive camera models have both.
There are pros and cons for both options.
Looking through a viewfinder, the operator can concentrate on taking photos. This is vitally important with portraiture – you want to be communicating with your subject, not ‘dumping,’ that is, looking at the LCD screen too often.
2) LCD Screen (Liquid Crystal Display)
The glaring disadvantage of an LCD display is that it’s difficult to see in bright sunshine. Nevertheless, this electronic display is brilliant for reviewing images and enables you to immediately see if your photo is any good. And, if you own a DSLR, use Live View mode so you can predict exactly what the shot will look like before pressing the shutter.
