How to get sharp focus in photography

Image
1.  Use manual focus.   While the auto-focus in our cameras and lenses are often superb, nothing will get you consistently sharp images than manual focusing—even in low light. The great thing is that it is also very easy to do. Switch from using your View Finder to using Live View. Then find the magnifying button on your camera. By pressing this, you will zoom into a selected area of the scene. Once you have switched to manual focus, simply adjust the focus ring until the details sharpen. Now zoom out. That’s it! 2.  Mirror lock up.  When we take a photo, the mirror in our DSLRs slap up and down to let light into the sensor. This movement can shake the camera very slightly, which especially in longer exposures, can create a blurry image. Fortunately, if you’re already in Live View this will lock the mirror up during shooting (for most cameras, but not all). On some cameras, the mirror still slaps down when using Live View. In which case, visit the in-camera menu and look fo

How to control camera manually

Image
You can  control  the shutter speed by setting the  camera  to 'S', or 'shutter priority' mode, if available, or by using 'M' ( manual ). The  camera  will always tell you the current shutter speed as you line up a shot, either on a top-mounted LCD (on this camera ), in the viewfinder or on the rear LCD display. You are smarter than your camera. That’s it. That’s all you need to believe. Unfortunately, you’re going to need to prove it. So what decisions should you make that your camera’s computer never should? The answer is actually quite simple. You need to control the most fundamental features that are the same now as they were fifty years ago: ISO, white balance (WB), aperture (Av), shutter speed (Tv), and focus. So I’m going to talk a bit about my thought process when setting these features manually. I don’t intend to teach you how to make the adjustments or what they are as there exists countless guides that do that already. ISO & Whit

what is depth of field

Image
In optics, particularly as it relates to film and photography,  depth of field  ( DOF ), also called  focus range  or  effective focus range , is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions. In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.

Exposure (photography)

Image
In photography,  exposure  is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. In photographic jargon,  an exposure  is a single shutter cycle. For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image. For the same film speed, the accumulated  photometric exposure  ( H v ) should be similar in both cases.

what is iso in camera

Image
                       In Digital Photography  ISO  measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your  camera  is to light and the finer the grain. Higher ISO  settings are generally used in darker situations to get faster shutter speeds.

what is shutter in camera

Image
                                    what is shutter in camera Shutter  speed exists because of something known as your camera shutter  — which, simply put, is a curtain in front of the  camera  sensor that stays closed until the  camera  fires. When the  camera  fires, the  shutter  opens and fully exposes the  camera  sensor to the light that has passed through your lens                                                                                                                                      kind of shutter leaf shuttter focal plane shutter                                                          A leaf shutter is a shutter as found in certain cameras, using of a small number of identical overlapping metal blades, called the leaves, to open and close in order to expose a photograph. It is usually placed near the iris within the camera lens. The leaves are arranged in a circular pattern, suitably pivoted near the housing periphery, and made to move in a rapi

what is aperture in Camera

Image
                              what is aperture in photography       In optics, an  aperture  is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical systemdetermine the cone angle of a bundle of  rays  that come to a  focus  in the  image plane . The aperture determines how  collimated  the admitted rays are, which is of great importance for the appearance at the image plane. [2]  If an aperture is wide, then highly collimated rays are admitted, resulting in a sharp focus at the image plane. A narrow aperture admits uncollimated rays, resulting in a sharp focus only for rays coming from a certain distance. This means that a narrow aperture results in an image that is sharp for things at the correct distance. The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time).
