Filters and Photography Filters can add special effects or abilities to your camera lens. Understanding how filters work will give you an extra arsenal of equipment to create that magical shot you’ve been looking for. Most lenses have the ability to add filters, primarily by screwing them on in front of the lens while some lenses require the filters to be attached at the rear end of the lens. Filters are used for several different reasons: increasing contrast, changing the exposure, capturing invisible light or minimizing reflections are just a few to name. The use of filters has gone downhill in this age of digital photography. These days it’s simply easier to make these changes in post-production instead of using a filter during the photo shoot. While that might be true, there are still some things we can’t change in post-production, and filters can become a necessity. UV Filters UV stands for Ultraviolet, which is light that is invisible to the human eye. ND Filters Graduated ND Filters Polarizing Filters
Comment choisir son objectif photo ? Quel dommage de manquer de temps pour dompter votre matériel photo. Ne pensez-vous pas qu'il est temps de réagir ? Après avoir lu cet article, vous apprendrez à réussir des photos dont vous êtes fier sans perdre une minute sur vos journées bien remplies. Mon conseil pour bien choisir l'objectif de son reflex (ou même d'un APN compact) : il faut partir des photos tout simplement. Il y a beaucoup de critères techniques et dans ce 70ème épisode audio, nous retiendrons les principaux : la focale, l'ouverture, le piqué, le prix, le poids et l'encombrement (après tout le meilleur objectif s'il reste dans votre placard ne sert pas à grand chose). Comment établir les priorités entre tous ces critères ? Traduits dans vos photos, ces critères déterminent la composition, le cadrage, la profondeur de champ, le flou de bougé, la perspective. L'édito poursuit la discussion sur la première vidéo payante de Déclencheur et vous présente l'état actuel de ma réflexion. A écouter pour aller plus loin
How to create HDR Photos - HDR/Photomatix tutorial | Abduzeedo | There has been a lot of buzz recently about HDR photography, but many people assume that it's only limited to professional photographers. The reality is that just about anyone can take and process an HDR photo with most cameras and proper HDR software. There are plenty of explanations of what HDR is and how it works, so we won't cover that here. If you want more background info, check out HDR explained so anyone can understand or Jon Meyer's popular HDR primer. In this tutorial we'll go through the steps necessary to take your very own HDR photo and process it like a pro. A camera that allows you to adjust exposure settings. Step 1: Taking the photo(s) TITLE: Quick and Easy steps to take HDR Photos with any camera To create an HDR photo you need at least 3 differently exposed photos of the same shot. Important: Make sure the camera does not move between shots. 1. 2. 3. The first is exposed just right (0), the second too dark (-2), and the third exposed too light (+2).

Polarizers Care, Feeding & Proper Use There are few more important things that a nature photographer can do to improve his or her photography than becoming familiar with the use of the polarizing filter. What can a polarizing filter do for you? Among other things it can darken the sky, remove reflections from water, and make foliage appear less shiny. Colour saturation is also significantly enhanced. It is the only filter for use with colour film that can do all of this. Lone Crane � Yucatan, 2002 Photographed with a Pentax 645NII and Pentax (67) 200mm f/4 lens on Provia 100F � Polarizer As seen above the use of a polarizing has been effective in removing reflections and glare from the surface of the water, and also in increasing the saturation of the colours beneath the water. Polarization and Wide Angle Lenses There are two issues to keep in mind when using a polarizing filter and a wide angle lens. Tumbleweed Dunes, 2000 Polarization is most effective at 90 degrees to the sun. Sunglasses

HDR Style Results Using Layers in Photoshop In this post Nathan Pask takes a look at a technique to get HDR Style Images Using Layers in Photoshop. There currently seems to be a lot of interest in HDR or similar processes. What is HDR? Essentially, it’s about collecting a series of shots taken on a tripod at different exposures and allowing über clever software to merge them together to make one supposedly perfectly exposed image. There are various types of software or plug-ins such as Photoshop, Photomatrix or FDR Tools that make producing a HDR image fairly straight forward. Does the final result look pleasing to the eye? So to begin, you need to a good sturdy tripod. The following process is using Adobe Photoshop. It doesn’t really matter, but I tend to use my darkest layer as my base just because it’s logical. Click back on your darker image that you have been dragging the layers on to. Click on the little eye icon on the left hand side of the ‘Background’ layer so it makes this particular layer invisible.
How to Use Ultra-Wide Lenses August 2008 Nikon Reviews Canon Reviews Leica Reviews Pentax Reviews Introduction Ultrawide lenses are the most difficult lenses to use well. Ultrawides are not for "getting it all in." Ultrawides are for getting yourself, and therefore the viewer, right smack into the middle of something. Ultrawides are for putting next to the muzzle of Dirty Harry's revolver to put it in your face. Ultrawides rub the viewer's nose in your subject. Ultrawide lenses are for getting close and bringing the viewer into the photo, not for fitting a subject into a photo. Ultrawides are not for the faint of heart. Most people use ultrawides too sheepishly, and get crummy results with tiny subjects dwarfed in the middle of an open frame. Ultrawides require you to get very close and personal to anything you are shooting. If you use them properly, you'll be rewarded with dynamic images. My 17-35mm zoom always seems to be shot at 17mm, my 16-35mm always at 16mm, and my 14-24mm always seems to be at the 14mm stop.
Conseils pour le portrait - Partie 1 : préparation et lumière | Guillaume Ménant | Photographe Amateur | Rennes Dans la continuité de mes précédents articles pratico-techniques, je vais essayer de rassembler des conseils/techniques que j’essaye en général d’avoir en tête avant et pendant une séance portrait à travers 2 articles. Je fais d’abord ça car j’ai une mémoire de poisson rouge et ça m’aidera donc sûrement à les appliquer moi-même et j’en profite du coup pour le partager. Ce premier article porte sur la partie préparation d’une séance portrait ainsi que sur la gestion de la lumière pendant la prise de vue. Je précise aussi avant de commencer que ce que j’écris ci-dessous n’est pas parole d’évangile et n’est bien-sûr pas exhaustif, je ne prétends pas être un expert du portrait (loin de là) mais j’essaye juste de partager le peu que je sais. La préparation La première étape avant une séance portrait est en général de prévoir ce qu’on va faire. Une dernière chose qui peut aussi être intéressante est de prévoir quelques croquis des images que vous avez en tête (cadrage, sources de lumière, …).
Infrared Photography with a Digital Camera Fogging Certain cameras or lenses may exhibit some fogging, or image areas with extra exposure (for example, a bright central spot seen with many Canon lenses). This may be due to light scattered from inner surfaces of the lens, or to some peculiarities of anti-reflective lens coating which was not really designed for infrared. Sometimes the blackness of internal surfaces of the lens tube or mirror chamber may be "not black enough" in infrared. Sometimes it happens to all cameras of a given model, sometimes — just to a particular specimen or a particular lens. Note to SLR users: regardless of that effect, the image may be fogged, or otherwise affected, by the light entering through the viewfinder in spite of the raised mirror) and reaching the sensor after being scattered around the mirror chamber. Gisle Hannemyr provides a list of lenses checked to produce a hot spot or fogging (or to be free of these effects) in his Digital Infrared Resource Page. Focusing Postprocessing
Choosing a Camera Lens Filter Camera lens filters still have many uses in digital photography, and should be an important part of any photographer's camera bag. These can include polarizing filters to reduce glare and improve saturation, or simple UV/haze filters to provide extra protection for the front of your lens. This tutorial aims to familiarize one with these and other filter options that cannot be reproduced using digital editing techniques. Common problems/disadvantages and filter sizes are discussed towards the end. The most commonly used filters for digital photography include polarizing (linear/circular), UV/haze, neutral density, graduated neutral density and warming/cooling or color filters. Polarizing filters (aka "polarizers") are perhaps the most important of any filter for landscape photography. two separate handheld photos taken seconds apart Note how the sky becomes a much darker blue, and how the foliage/rocks acquire slightly more color saturation. Linear vs. GND filters come in many varieties.
