Using Your Camera's Histogram to Take Better Digital Photographs - Envato Tuts+ Design & Illustration Tutorial. The histogram is one of the best ways to check for accurate exposure in the camera, and yet it's underused by many photographers.
Use this tutorial to learn to use histograms in-camera and as part of further Photoshop processing. 1. Understand What the Histogram Represents. Using Your Camera's Histogram to Take Better Digital Photographs. The designer's guide to image compression. Whether you're a designer working for print, the web or TV and film, image compression is a necessary tool that you'll use on a daily basis.
Without it, we'd be emailing files that take up hundreds of megabytes, trying to send large files would take hours, your landing page would never appear, and browsing the web would be like walking through treacle. All modern design tools have complex built-in image compression algorithms that abstract the decision-making process from designers.
But having a clear understanding of how and why image files are compressed can help ensure your output is accurate and reproduces as you intended. Here we'll walk you through the basic terms and concepts of image compression that all designers need to know, then look at some of the more useful tools on the market to help you out. 01.

Flash Photography Basics, an Introduction The reason to use flash is of course that flash is very bright (and very fast) for easy camera exposure.
In comparison, the brightest light bulbs are dim for photography, not near sunlight bright. Without flash, even well lighted rooms will suffer from long slow shutter speeds, or high ISO, or both. Light bulbs can be fine for still life photography, when a one second shutter is no problem, but which is unacceptable for pictures of people, who tend to move. Flash also allows us to create the lighting, to be like we want it, to place flash wherever we want them, and to be made soft as we might desire, etc. Flash photography is many things. In short summary, the major points, the really big deal about flash, is: The intensity of any near light source (flash or continuous) falls off fast with distance (inverse square law). Flash is just a light that we can aim. HDR and Flash for Real Estate Photography. Lights, camera, nostalgia! The rebirth of Studio Harcourt.
[Fstoppers Original] What Is Lens Diffraction And When Does Diffraction Happen? If you are like me then you might not always get caught up in some of the super technical aspects of photography.
One aspect of photography I recently investigated was the loss of sharpness caused by Diffraction. Last night while playing with the new Nikon D800 camera I examined lens diffraction and how diffraction can seriously affect the sharpness of your photography. One thing that always blew my mind in science class was when my professors told me light can act both as a particle and as a wave (quantum physics was never my strong suit). When described as a wave, light usually travels in a straight line but can also bend when passing through or around objects.
When light travels through your camera's lens and through a large aperture, light doesn't bend or disperse all that much. Tips for Phone/Tablet Art Photography.

This shot was produced merely as an exercise, and not for a client or the watch manufacturer. Honestly – had it been for a client It would of been a re-shoot due to some of the issues I came across. More about those later.. Exposure Compensation. I believe I have a reasonably secure understanding of exposure – i.e. use and relevance of ISO, aperture and shutter speed – and the purpose of and when to use exposure compensation. Nowadays, I use the histogram to act as a guide to exposure – as I don’t have ‘LiveView’ this is a retrospective action when I review the shot on the back of the camera. Nevertheless, I can see what’s going on and can make another exposure if I believe my first attempt is not right.
Exposure Compensation. Exposure compensation. For the first six months of my relationship with my Canon 40D SLR, I did not know a quick way to correct exposure. I would take a photo that was too dark or too light, and I would start fumbling around with the f-stop and/or shutter speed to correct it and by that time my subject was in the kitchen eating lunch. I'd shrug my shoulders and set my camera down. Then! I discovered the wonderful little secret that is exposure compensation. This handy little feature has made picture-taking a million times easier.

Evolving Beauty, Eric Boutilier-Brown. From 1991 to 2005, my main camera was always a large format camera.
Also know as a view camera, a large format camera makes images on individual sheets of film (as opposed to 35mm and medium cameras, which use film formed into a long roll, with multiple exposures made on the roll before it is fully exposed). The main reasons for using large format cameras (also called view cameras) is the film size and the camera movements. Most people who use large format cameras use 4"x5” cameras - these have a good balance between size, flexibility and expense. I used a 4"x5” view camera consistantly from 1991 to 2001. Between 2001 and 2005, I worked exclusively with an 8"x10” large format camera. Toepassingen van een tilt-shift lens. Using Tilt-Shift Lenses to Control Perspective. Tilt shift lenses enable photographers to transcend the normal restrictions of depth of field and perspective. Many of the optical tricks these lenses permit could not otherwise be reproduced digitally—making them a must for certain landscape, architectural and product photography.
The first part of this tutorial addresses the shift feature, and focuses on its use for in digital SLR cameras for perspective control and panoramas. The second part focuses on using tilt shift lenses to control depth of field. Shift movements enable the photographer to shift the location of the lens's imaging circle relative to the digital camera sensor. This means that the lens's center of perspective no longer corresponds the the image's center of perspective, and produces an effect similar to only using a crop from the side of a correspondingly wider angle lens.
Tilt movements enable the photographer to tilt the plane of sharpest focus so that it no longer lies perpendicular to the lens axis. My Photo Lesson; TCM Productions; Tom Moore. Zil Fotografie MBO niveau 2. LR/Enfuse for InteriorsPhotographer's Toolbox. You may have seen the me mention this photo in a previous post. The shot is taken using ambient light only, and yet everything is well exposed from the forground table right through to the back of the room.
Normally we would expect most of the room to fall into shadow due to the high constrast difference between the window-lit table and the shaded corridor; so how was this avoided? Well, it was easy actually. How to Pre-Visualize like Ansel Adams - The concept of previsualization in photography is where the photographer can see the final print before the image has been captured. Ansel Adams dedicates the beginning of his first book to previsualization, and is often quoted as saying “Visualization is the single most important factor in photography”. Understanding then the significance of this approach is of high value for photographers of all kinds, as it has the potential to unlock greater creative vision, and give greater control (and predictability) over the print process. The writing of Ansel Adams is often times a bit abstract for the layman, if not highly complex.
I have attempted to consolidate some of his thoughts on previsualization, and I hope to explain in plain english how you can incorporate his ideas into practical terms. Let’s start at the beginning.
