The Inverted Image: Silk purse from a Sow's ear? Some of you may have heard of this old proverb, (dating back to the 14th century), but it tends to be less commonly used nowadays, although a bit more commonly with photography. Anyway, what am I talking about this time you may well ask. Read on to find out more... The old proverbs full use is, "You can't make a silk purse from a sow's ear", and yet I see people attempting similar things all the time, especially with photography. Taking an awful picture, cranking it through a HDR package and now we have, well an awful picture in HDR really. Similar things occur with all sorts of post-processing especially with the ease of manipulation that digital photography gives us nowadays.
Yet a sculptor of stone starts with a mediocre looking block, a few battered tools and turns it into a work of art, (sometimes). Take a look at a painting in progress, (if the artist will allow you and most don't), and you'll see big blobs of paint and swashes of colour spread across the canvas. Original here .

So, what we have here is a solution to a problem which has come up recently for me. The problem being that I’ve been shooting mostly film lately and I have a whole bunch of negatives longing to be digitized… So I thought I’d help them little guys out. After a bit of pondering I came up with what you see below. Pretty simple, eh? All you have to do is find yourself a cardboard box and a piece of matte white cardstock. Cut an appropriate size rectangle in the center of one of the sides. Now insert your cardstock at a 45° angle to the hole you just made. Center your lens on the slide and make sure it’s level, or else things may look a little wonky. That’s it! I’ll be doing another post shortly on what to do with your RAW scans to get them to look like positive images you’d get back from the photolab. Monitor Color Calibration for free using your DSLR » Pictures and Code.
18th May 2007 Color perception is subject to ambient light levels, and the ambient white point. (A red object looks black in blue light.) It is therefore not possible to achieve calibration that will be perceived evenly in different lighting conditions. The computer display and calibration target will have to be considered in controlled predefined lighting conditions. Controlled lighting conditions such as D65 help to suppress the effect of metameric colors which would further complicate the issue. At first look for the light sources in at your working place: Avoid these old yellow light bulbs for your room with the monitor and replace these with newer energy saving daylight bulbs.Try to avoid mixed lights of different color temperatures.
Step-by-Step Tutorial: Place some neutral grey objects in the area behind your screen that you would see from the position where you are working. In OS X it is like this. Ok, now comes the hard work.

November 25, 2010 Posted by Sean McCormack Timothy Armes has today announced a series of “Web Site Publisher Pro” plugins that offer users a revolutionary new way to create an entire web presence, including multiple content pages and a complete hierarchy of galleries, from within Lightroom 3. Rather than creating a single gallery in the web module you instead design the look and feel of your entire site from there, and to actually create and upload a site you then use the Publish Services in the library module.
By adding collections and collection sets to the publish service you can create a complete web site that includes a full structured hierarchy of galleries. When images are added or modified the publish service will only upload the changes (unlike the web module which needs to upload the whole site). The first plugin in the series to be made available is Timothy’s Impact Web Engine, however versions for Elegance and Jigasawrus will be coming soon. More info can be found here: Blog: Techniques. Just to turn things around a bit (like above), the discussion "what lenses do you prefer?
" could instead start something like "what do you prefer to photograph? ", and then leading over to lens choice. "I hate zooms", for example, is pretty well-heard when discussing lenses. Sure, I do too, most of the time, but not at those instances when I'm in an airplane; up there it's the perfect horse. It takes too much time to change a composition using the radio to move an airplane closer or farther away, so a zoom is much needed, and the bigger depth of field is not a problem compared to fixed lenses, since the surroundings are normally calm anyway.
On the other hand, when trying to reduce a cluttered room to get some attention on the person occupying that mess, f/2.8 just don't work that well for me; f/1.2 or f/1.4 is more like it. Or when trying to balance low ambient with flash, and wanting to get as much ambient into that exposure without using a tripod, f/1.2 is a lot better than 2.8. Playful Indulgences with Adobe Pixel Blender for Photoshop. Sometimes I just find I have a need to play. Not the sand lot type, even though that might be fun, but more along the lines of creativity with my artworks.
With painting I can just slop the wonderful colors around and see what happens but clean-up is more effort. But with photography it's not always as easy. I could throw my camera up in the air with a timed shutter and see what happens, but I am afraid of dropping it and then seeing a lot on money becoming dust on the ground with a broken camera. Digital editing allows me that freedom and the only cost is my time.
I came across a video that shows the use of an Adobe Labs plug-in for Photoshop CS 4&5 called Pixel Bender. The above image was run once in pixel bender to give texture in the parrot, but I found that the remaining detail was all too much the same and still too fine in detail for the background. The 2 photos of the fall scene are identical except for image resolution. It's easy to see the difference in effects. Niels Henriksen. Сайт Виктора Лушникова. Bokeh. Un article de Wikipédia, l'encyclopédie libre. Un bokeh (se prononce comme « boka »[réf. nécessaire]) est un flou d'arrière plan d'une photographie permettant de détacher le sujet de son environnement.
Étymologie[modifier | modifier le code] Le terme vient du japonais boke (ぼけ, boke?) Que l’on traduit par flou ou de bokashi, qui décrit la gradation de couleurs dans la gravure japonaise sur bois[1]. Si ce terme est aujourd’hui couramment utilisé par les internautes amateurs de photographie, il n’est apparu dans les livres de photographie qu’à la fin des années 1990. Description[modifier | modifier le code] Taches pentagonales formées par un diaphragme à 5 lamelles. Pour obtenir un bokeh satisfaisant, on utilise de préférence un objectif lumineux (avec une grande ouverture), un objectif macro (cet aspect est généralement très travaillé sur ces objectifs) ou un téléobjectif.
Le mot bokeh en lui-même n'implique aucune connotation esthétique. Exemples de bokeh[modifier | modifier le code] Polarisation (optique) Exemple de banc de polarisation. Dans une onde électromagnétique polarisée (linéairement), le champ électrique et le champ magnétique oscillent simultanément dans des directions perpendiculaires l'une à l'autre. Par convention, la polarisation de la lumière décrit la vibration du champ électrique et quand l'onde est polarisée linéairement, ce champ oscille dans une seule direction.
Quand une onde est constituée de deux composantes polarisées à 90° l'une de l'autre, ET en déphasage de 90° également l'une par rapport à l'autre, alors, sa polarisation semble tourner autour de l'axe de propagation de l'onde. On parle dans ce cas de polarisation circulaire ou elliptique (quand les deux composantes n'ont pas la même intensité). Le sens de la rotation, droite ou gauche, dépend du sens du déphasage entre les deux composantes et est également un paramètre clé qu'il faut mettre en regard de la biréfringence et de l'activité optique des milieux traversés.

When you start your dive, you should have an idea of what you are looking for, the type of habitat it lives in, and what depth ranges it is at. so you find a subject, now what? If another photographer is shooting the subject, be careful not to get too close, or to cause silt to flow towards them. You must be able to evaluate the potential of a subject.
Bright colors make for great macro subjects.

Create a Vibrant Lighting Effect With Cross Polarization. Light has the ability to create many different types of dramatic effect, though there is none as vivid as cross polarization. It awakens the imagination with its vibrance of colors. Though this technique was popular 20+ years ago, it seems to have been lost in the digital shuffle. This tutorial will walk you through the process and equipment to experiment with cross polarization. Final Image Preview Introduction As I was a commercial artist/photographer 20+ years ago (and I love great cross polarization) I will lay before you the "secrets" of this phenomenal lighting technique.
Step 1: What You Need and What I Use The first, and most obvious, item is a camera. Shown below is my Gepe Slim Lite 5000 with film in place. Step 2: The Subjects Cross Polarization is actually a scientific application that finds weaknesses in glass and plastic. Step 3: Set Up the Shot The photo of the setup shows that I placed the Linear Polarizing Film directly between my light source and my subject.
Conclusion. A bug's eye view: The incredible close-up images of insects. By Daily Mail Reporter Updated: 15:22 GMT, 21 October 2010 Up close they look like the terrifying products of a fevered imagination. And with their lurid colours, bulging eyes and other-worldly faces these insects can certainly look rather alarming. But for amateur bug photographer John Hallmen there is a hidden beauty in seeing these creatures up close and personal. A male Anthomyiid fly on dry grass covered in frost, which look like tiny crystal balls as they balance on his body Close-up images, taken in the Mr Hallmen's studio, of a black ant, left, and a horsefly with its vivid green eyes Mr Hallmen has been fascinated by insects since he was a boy.
In the last three years he's made a name for himself by photographing the tiny animals he finds in the Nackareservatet nature reserve near his home in Stockholm, Sweden. Using a mixture of studio and alfresco shots John magnifies his images up to 23 times to show the beautiful colour and detail in his subjects' bug-eyed faces. Enlarge. Focus Stacking: Getting the Shots in the First Place. Focus Stacking: Getting the Shots in the First Place Shooting for focus stacking can range from easy to maddeningly frustrating depending on how many shots you need to take. The higher the magnification, the shallower the depth of field and the more shots you need to get the results you really hope for. Here are two good solutions to make your shooting easier. Your eyes automatically adjust focus when you look at a scene but not when you look at a photograph of that scene.
Whatever depth of field you capture is all there is in that photograph. Focus stacking is a technique that uses software to combine multiple shots taken at different focus distances to form a composite result with greater depth of field. To make use of focus stacking, you need to first set your camera on manual exposure to ensure that all images you shoot will be consistent. All of this tends to be more difficult when shooting macro than landscape images. What I use I've mentioned briefly before. Markus Keinath's Photohomepage - Camera And Lens DIY, Repair, Modification.

Power Zoom The zoom is motorized. The motor allows for three zooming speeds at a small twist of the zoom ring. On cameras without support for power zoom the lens can be zoomed manually by turning the zoom ring. 2. The zoom lens retracts to its shortest physical size when powered off. 3. You can preset a focal length and you can then recall that focal length by pressing the zoom setting button on the lens. 4. You compose using the viewfinder so that an object (e.g. a child) fills the frame as you desire (e.g. a full body shot). 5. The lens will automatically zoom from wide angle to tele during exposure thus creating a special effect where the subject diffuses radically outward.
Which Camera Bodies Support Power Zoom? All five modes are supported by the PZ series of film bodies. Finally, a group of Pentax DSLRs do not support Power Zoom at all: *istD series, K100D, K110D, K-m/K2000, K-x and K-r.
