Tips to Emphasize Your Subject in Photography 1. Get in closer. When you get in really close to the subject it starts to fill the whole frame and the eye can no longer miss the subject. It powerfully directs your attention to the subject, as there is nothing else in the image to compete with it. It is a simple but dramatic emphasis of a subject.

- Point of Focus and Depth of Field. When a photographer uses the term point of focus, he is referring to that object in a photograph at which he wants to draw the most attention. Focus itself refers to the amount of the image that is sharp. Both the point of focus and the amount of focus affect the resulting image. In short, altering each one changes the look of the final photograph. In these two images, the point of focus was the same, the coneflower. However, the amount of the photo in focus, or the amount of sharpness, also called depth of field, is different. Let's deal with these subjects one at a time.

Canon Lenses STM vs USM (Focusing Face-off) The focusing method used when looking through the viewfinder, not the LCD. In the Canon T4i when you focus through the viewfinder you use what I call the big brains of the camera and the focusing method used is called Phase Detection. So how does the two new STM lenses compare with a USM. Real Quick Definitions.

- The Hoya Variable Density Filter uses two polarizing layers to control the amount of light that passes through the filter and into the camera lens. At its minimum effect, the filter passes 1/3 of the light in a scene. That is equal to 1.5 stops on the aperture or shutter speed.

Digital single-lens reflex camera A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor.

How Image Stacking Works The classic application of image stacking is to increase the signal-to-noise ratio (snr). This sounds technical and confusing at first, but it is really simple to understand. Let's look at it in parts and then see how the whole thing works. The first thing you must realize is that this is a pixel-by-pixel operation.Each pixel is operated on completely independent of all other other pixels.his is another crucial aspect of how stacking allows dim parts of an image to become apparent. It is for this same reason that, in each raw frame, the bright parts, although noisy, are quite discernable in their basic structure, while the dim parts can appear virtually incomprehensible. So that's what stacking does.

Push processing Unsourced material may be challenged and removed. (June 2009) (Learn how and when to remove this template message) Push processing in photography, sometimes called uprating, refers to a film developing technique that increases the effective sensitivity of the film being processed. Push processing involves developing the film for more time, possibly in combination with a higher temperature, than the manufacturer's recommendations. This technique results in effective overdevelopment of the film, compensating for underexposure in the camera. 1 Visual characteristics.
