Portraits with Two Lights: Adding a Fill Light. A second light source — usually called a fill light or fill flash — can greatly improve portrait lighting. It reduces the depth of shadows and softens the appearance of facial features, amongst other traits. Best of all, a fill light is easy to create: either a simple on-camera flash or a reflector is often sufficient. However, a second light source can just as easily harm portraits. This tutorial therefore focuses on how to control the location and intensity of the fill light in order to produce a desired portrait appearance. Harsh Overhead Sunlight Sunlight with a Fill Flash If you haven't done so already, also take a look at the first part of this tutorial:Introduction to Portrait Lighting: One Light Source With a single light source, the most important considerations were its direction and apparent size.
Note: diagrams show the effect of a fill light, not necessarily its ideal position (more on this later) Portraiture typically appears better with a flash ratio near 1:2. Reflectors. A Tedious Explanation of the f/stop. By Matthew Cole Photographers set their exposure using a combination of shutter speeds and f/stops to get the correct amount of light on the sensor (or film). The shutter speed regulates how long the sensor is exposed to light coming through the lens. The f/stop regulates how much light is allowed through the lens by varying the size of the hole the light comes through. For any given film speed (ISO) and lighting combination there is one correct amount of light to properly expose the image.
This amount of light can be achieved with many different combinations of f/stops and shutter speeds. Back in the days of film, that was pretty much it for exposure because your ISO (and white balance too) was set by your film choice and you couldn't vary it within the roll. That's changed. Fill That Bucket! My favorite analogy for exposure is filling a bucket with water. Shutter Speeds Shutter speeds are a bit easier to understand, so I'll start with those. F/Stops Yes. Got it, I think. No. Yep. Bernie’s Better Guide to Depth of Field for Geeks Who Want to be Digital Artists | Bernie Sumption :: Photography. Being a guide to portrait photography cleverly masquerading as a technical analysis Like the topics we covered in the beginner's guide last month, depth of field might initially seem complex, but behind it is some relatively simple logic and maths.
Don't worry if maths isn't your strong point: long equations are the crutch of the inarticulate, and there's nothing in this article more complicated than division. Speaking of division, I like to divide photography into two broad disciplines. Portraits are photos of a particular object (not necessarily a person), designed to capture something about that object. Landscapes are photos of a scene (not necessarily outdoors), designed to capture the sensation of being in a place. I say that this is a disguised guide to portrait photography because mastering depth of field is one of the main skills you need to take great portraits. The following image depicts a (fake) flower about 50cm away, with a hedge around 5 meters behind it.
Depth of field 1. What do numbers letters on digital camera lens mean (Website Design Tips) What do all the numbers and letters on a digital camera lens refer to and what do they mean? If your new to DSLR photography the first things you'll need to know when buying a new lens will be concerning the numbers and letters printed on the lens. You will need to know what they mean to ensure you buy the lens that suits your specific needs.
First I'll start explaining what the mm number means. For example on a Canon EF-S 17-85mm f/4-5.6 lens you will see the number 17-85mm written on the side. The mm number refers to the focal length. This is the length or distance from the front of the lens to the camera's sensor. The focal length is one of the most important considerations a photographer needs to take into account when buying a new lens. For example, the smaller the mm number the wider the angle of view within a photograph. On the other end of the scale, big mm numbers like 200mm or 300mm provide a magnified telephoto view. What does the ratio number mean? What does Ø58mm mean? Online Depth of Field Calculator. Weather Photography: lightning, clouds, atmospheric optics & astronomy.
