HOW TO USE TILT-SHIFT LENS FOR FOOD PHOTO
When it comes to food photography or food photography, the photographer’s arsenal has several perfect lenses. One of them is a tilt-shift lens. It allows you to creatively work with the depth of field and perspective of your photos. Tilt-shift lenses are often used in architectural photography – they solve problems with controlling perspectives and help visually align the “falling buildings” in the photo.
How to use tilt-shift lens for food photography
Read our article in which photographer Darina Kopcok helps to learn more about how these lenses are useful for food photography and food photography.
What is a tilt shift lens?
Commercial food photographers or still-life photographers constantly use tilt-shift lenses in their work. Such a lens cannot be called a “budget option”, but it is still worth investing in it if you plan to specialize in food photography and will often use it. Continue reading
WHAT IS A DECENTRATED LENS?
A decentralized lens contains one or more elements of an optical lens that are either shifted or tilted from its main axis. Such a shift or tilt of the lens elements can potentially lead to blurring / softness of parts of the image due to the divergence of light rays. While in many lenses you can observe very slight decentration of the optical elements, especially on super zoom, strong decentration and tilt can make the whole image blurry, because the lens cannot achieve good sharpness over the entire frame.
It is always useful to check the lens before buying, even if it is brand new. Unfortunately, despite the efforts of manufacturers to manufacture each lens, many things may go wrong once you get your copy. In some cases, this is the manufacturer’s fault (poor quality guarantee / low standards), and in some cases it’s the fault of some guy who casually throws a box with a lens during transportation. Unfortunately, these conditions can negatively affect the operation of the lens and create all kinds of problems. Decentration of lens elements is one such problem, as photographer Nasim Mansurov talks about in a blog post. Continue reading
What is ISO and how to configure it
The ISO value is one of the most important settings when shooting, along with such values as shutter speed, aperture, and white balance. ISO is also often referred to as ISO sensitivity, ISO level, or simply the photosensitivity of a matrix or film.
Still, what is ISO in the settings of the camera?
ISO is a parameter indicating the level of sensitivity to light of its light-picking element (matrix or film). Basically indicate the limits of ISO for cameras (cameras). Although, the same parameter can be found not only on the camera, but, for example, on the flash. For a flash, a guide number is usually indicated when using one of the ISO values of 100, or 200. ISO sensitivity is indicated in special units of the ISO system. The ISO numeric expression itself can accept any integer expression from 1 to infinity. For example, on my SB-900, you can set the ISO from 1 (unit) to 12,500, and on my Nikon D40 you can set the ISO value from 200 to 1,600. Continue reading
