Digital Photography Revealed

 Powered by Max Banner Ads 

Many people love their Digital SLR cameras as the photo quality is on a whole other level. It just becomes a difficult question when deciding which lens to buy for your DSLR as the specifications are just a little too in depth. Here\’s a breakdown of all you need to know about how to buy lenses for your DSLR\’s.

The initial point to remember is that most companies don\’t make lenses that aren\’t compatible with their own cameras, like the Canon t3i bundle. So be aware of this point when buying lenses compatible with the camera you have at home.

There is a also a lot of technicalities when determining what lens to choose from so here is a quick tip. Keep in mind of what you want from your camera, whether its photo quality or zooming factors, as this will be the deciding factor.

\”Mid-range\” or \”standard\” lengths of focus range from roughly 35mm to around 70-80mm and therefore the quality captured is extremely close to what the human eye can get!

A shorter focal length will result in having a wider field of view of your desired subject. This is referred to as a wide angle lens, since it has a relatively short focus, but it is a little different from the mid range lenses as some quality is lost.

Understanding what you want to achieve with your digital camera is paramount to selecting the best lens for your needs. Do you intend on taking far away or close, small objects? In the case of the distant objects, a lens with zoom ability is right for you. In other words, the right lens really depends on your needs.

Having a \”wide-angle zoom\” lens, not only will you pay the higher range of prices, as the lens will probably equate to the same amount as your camera value brand new! The results are excellent, as your pictures will be wide, and will demonstrate the difference without hesitation.

Shooting portraits or dimly lit subjects will mean that you need a less wider view to focus. Having the right lens for this situation and combined with your photography experience, you will be able to shoot pictures of the best quality, despite the poor conditions.

With regards to buying such lenses, you can\’t go wrong with eBay or second hand electronics stores, online and offline. Make sure you keep your old lenses since if you happen to be compatible with your newer camera, this can save you a ton of money.

Photoshop plugins load into Photoshop\’s Filter menu when Photoshop launches. They add all sorts of extra functions to Photoshop. In the old days Photoshop plugins were just a bunch of weird effects.. Today, however, some very sophisticated plugins have been produced that aim at complicated image retouching that would otherwise have been impossible or very time consuming in Photoshop. More recent versions of Photoshop has been inspired by some old plugins and does similar things, like lens correction and proper black-white conversion.

But how does one install plugins into Photoshop, you may ask? Adobe Photoshop installs with a folder called Plug-Ins inside the Photoshop folder. All you have to do is place the plugins inside the Plug-Ins folder. When you launch Photoshop, the menu Filters will show your new plugins. If Photoshop was already running, when you installed the plugins, you will have to quit Photoshop and launch Photoshop anew. Actually you don\’t have to install the plugin into Photoshop\’s Plug-Ins folder. To install in any folder you like, follow these guidelines:

1. First make sure your alternative plugins folder exists, otherwise create it where ever you like. 2. Start Photoshop. 3. Go to the menu Edit and open it. Go to the bottom of the Edit menu to Preferences. Open Preferences. 4. Plug-Ins might be called \”Plug-Ins and Scratch Disk\” depending on your Photoshop version. Go there. 5. Activate Additional Plug-Ins Folder by checking it. 6. Click the button Choose to browse to your desired alternative Plug-Ins folder.

As simple as that! This alternative plugins folder can now be used to store all your personal plugins. Exit the preferences and relaunch Photoshop. The plugins in your alternative location will be listed at the bottom of the Filter menu next time you run Photoshop.

There are generally two types of plugins: 1. Retouching plugins. 2. Effects plugins. Retouching plugins tend to manipulate what is already in the photograph without adding anything new. Effects plugins on the other hand add, well, effects to the picture. Examples of retouching could be sharpening, exposure or saturation. Examples of effects plugins could be lens flare, bokeh or raster. The distinction is not always so easy. What about lens correction? Is that a retouch or an effect? It is a retouch if you correct barreling or pincushion, but if you make a regular image look like a fish eye photo, it is an effect.

Third party plugin were made possible in 1991 when Photoshop introduced the possibility in Photoshop 2. In 1994 Joe Ternasky released Filter Factory for writing third party plugins. In 1997 Alex Hunter released Filter Meister as an improvement over Filter Factory and many of today\’s plugins are written in Filter Meister. Ten years after Filter Meister was released, a novel approach to filter development was released as Filter Forge. Filter Forge plugins require Filter Forge to run and they are not stand alone. Filter Meister plugins are currently only for 32 bit Photoshop, but the developer, Alex Hunter, promises 64bit support will be released some time 2013. Filter Meister is only available for the Windows platform.

Based on: What are Photoshop Plugins? and Introducing Photoshop Plugins?

A non-technical term for how intense a specific color appears is \”colorfulness\”. Similar, but technically correct terms, are saturation and chroma (Munsell). Colorfulness can simply be said to be the degree of difference between a color and gray. But what gray? On the other hand the term saturation takes into consideration that fully saturated colors are not equally bright: For example blue is darker than yellow and red. Saturation thus means the colorfulness of a color in relation to its own inherent brightness. In general, terms such as saturation, chroma and colorfulness are used as synonyms. The more colorful a color is, the more vivid and intense it seems, while less colorful colors appear muted and closer to gray. A so called gray scale image is an image from which all color has been removed and saturation thus is 0.. There is an overlap between lightness and saturation in that a more saturated color appears lighter.

Lightness, or what is termed \”value\” in the Munsell color space, is defined as a given colors placement on a scale ranging from black to white. The Munsell color space, for example, divides the lightness axis, called value, into ten equidistant steps. The term \”lightness\”, on the other hand, stems from the HSL (Hue, Saturation, Lightness) and Lab color spaces. The HSV (Hue, Saturation, Value) color space speaks not of lightness but of value and uses the word value differently than Munsell does. Value in HSV does not range from black to white, but from black to the fully saturated color. Paints can be made lighter or darker by adding white or black, but that also reduces saturation. \”Tone\” is an obsolete term that stems from darkroom photography to denote the lightness of a specific area of the print. Yet \”tone\” is still used in art where light and dark \”tones\” are built up with charcoal or similar drawing medium

In digital photography lightness can be calculated simply as (r+g+b)/3. That, however, does not take into consideration that green is the brightest color and blue the darkest. The relative brightness of the color channels is taken into consideration in the IUV color space, that calculates lightness like this: i=(76*r+150*g+29*b)/256. The formula reflects the fact that green is about twice as bright as red and red about 2 times brighter than blue.

The term \”tone\” is used in painting where it denotes an intermediate between gray and pure color. \”Tint\” denotes a mixture of pure color with white and \”shade\”denotes a mixture of pure color with black. In reality tint and tone are not as simple a it sounds, because though they do not have color in themselves, when white or black are mixed with a color, the color changes hue. In other words, black in mixtures behaves like a blueish color. For example if you mix yellow and black you don\’t just get a darker yellow, but you get a darker and greenish yellow. Similarly will an addition of white make a color appear colder.

In software you can digitally create tints and shades by converting from the RGB color space to IUV or Lab color space and alter the L (lightness) channel as described above. This will not alter the hue of the color as when you mix pigments with black or white.

Photoshop plugins, or Photoshop filters as they are also called, add extra functions to Photoshop. They are automatically loaded into Photoshops Filter menu at start-up. Most plugins focus on effects that are hard to duplicate in Photoshop.. Recently a number of plugins have been produced, that do sophisticated image retouching that would otherwise be impossible or very time consuming in Photoshop. More recent versions of Photoshop has been inspired by some old plugins and does similar things, like lens correction and proper black-white conversion.

But how does one install plugins into Photoshop, you may ask? Adobe Photoshop installs with a folder called Plug-Ins inside the Photoshop folder. Place the plugins inside the Plug-Ins folder, and you are done. Launch Photoshop and the menu Filters will have your plugins listed. If you had Photoshop running, when you installed the new plugins, you will have to shut and relaunch Photoshop to see the new plugins. You can actually install the plugins in a different folder than Photoshop\’s Plug-Ins folder. To install in any folder you like, follow these guidelines:

1. First make sure you have an alternative plugins folder. Create it where ever you like and call it what you will. 2. Launch Photoshop. 3. Open the menu Edit. Go to the bottom of the Edit menu to Preferences. Open Preferences. 4. In Preferences go to Plug-Ins or Plug-Ins and Scratch Disk, depending on your Photoshop version. 5. Check Additional Plug-Ins Folder to activate it. 6. Use the Choose button to browse to your alternative plugins folder.

That\’s it! You can now store all your plugins in this alternative plugins folder. Exit the preferences and relaunch Photoshop. Next time you run Photoshop, the menu Filters should have all your personal plugins listed at the bottom.

Of course there are crossovers. Is lens correction a retouch or an effect, for example?

In the marketplace right now, there is a large range of digital cameras, but not all of them have the same purpose. If you intend on taking photographs underwater, you should consider getting a high quality camera that is waterproof. Here are some factors you should keep in mind:

You must choose a camera that has above average image quality. It is irrelevant if you take photos underwater or on land, the quality of the images should be close to perfect. Consider getting a camera with an excellent resolution rating, as well as adequate lighting and optical zoom functions.

Battery life is another thing you want to keep in mind when purchasing a camera. The last thing you want is a camera that dies after every few pictures. This will make your photo taking experience far from fun. The best thing to do is to look for a camera that has a rechargeable battery included. This means that you don\’t have to worry about running out and buying batteries all of the time.

The way the camera is made is not that important but you should still consider it. Many people buy certain digital cameras because of the way it looks. On the other hand, underwater digital cameras tend to be bulkier than regular digital cameras, but the advantage of this is that it is waterproof.

A big memory bank in cameras is something you should think about as well. Although most people buy memory cards to artificially increase their memory capacity, it doesn\’t stop the fact that the camera can suddenly stop working and the memory from that disappears. Cameras that can hold more than 10 photos are the way to go.

Brand means a lot when you are buying a camera because each company has a different level of help and support. If you purchase a camera from a company that is virtually unheard of, you may have a hard time trying to reach their customer service or tech support when you have trouble. Do not allow cheap prices to sway you since you want to be able to access help when you need it.

If you\’re looking to buy an underwater digital camera, these tips will definitely help you find the right one that suits your needs.

Chromatic aberration sounds difficult, but it is really quite simple. It is seen in photos as magenta and blue-green fringes produced by the lenses. Chromatic aberration can be created in two ways: 1. The different colors do not focus on the same sensor plane. 2. The individual colors produce images of different size. Here we will take a deeper look at what chromatic aberration is and how to avoid or solve it.

The first thing to grasp is refractive index, so let us briefly explain what that is. Light changes its direction when it passes through a medium like the glass of the lenses. For example light may hit the lens at a 90 degree angle, but leave the lens at an 80 degree angle. Chromatic aberration arises because the different colors of light have different refractive indexes. For example blue might leave the lens at 79 degrees while red might leave at 81 degrees. This difference will create thin magenta fringes known as longitudinal chromatic aberration. Since green is in-between red and blue it is used to focus the lens. Thus the red and blue are slightly out of focus which creates the magenta (red+blue) fringes.

Transverse chromatic aberration arises when light does not reach the lens at 90 degrees, but from a different angle. In this case the different colors focus evenly, but not at the same spot. This causes the red image to be larger than the green and blue, and the blue the smallest of them all.This also creates colored fringes, but now both a magenta and a blue-green one. It is in the interest of lens manufacturers to avoid chromatic aberration, but since it is in the nature of light, it is hard to eliminate.

You get different kinds of fringes for each kind of chromatic aberration. Longitudinal aberration creates magenta fringes around objects and is spread uniformly throughout the image. Transverse aberration is absent at the center of the image, but grows in intensity towards the image corners. Longitudinal chromatic aberration is most pronounced in wide aperture lenses. It can be minimized by using a small aperture. Transverse chromatic aberration is most pronounced in telephoto lenses. However, lenses can be designed in many ways. The so called achromatic lenses are by far the most popular with minimal chromatic aberration. Superacromatic and apochromatic lenses almost eliminate color errors, but they are not common. Chromatic aberration can be seen on film, but is most pronounced on digital images. One explanation is that the sensors are more sensitive to ultraviolet and infrared light, which are at the outer edge of the spectrum where aberration is most pronounced.

Software can correct chromatic aberration. Longitudinal chromatic aberration is somewhat corrected by sharpening the red and blue channels; the green channel is used to focus the image and should be sharp. Transverse chromatic aberration is satisfactorily corrected by radially enlarging the blue channel image and radially reducing the red channel image.

Purple fringing is a special kind of chromatic error. It appears along hard contrast edges when photographing something against a hard back light, or when photographing a light source against a dark background.The purple fringe invades the dark area. Purple fringes are sensor errors, whilst chromatic aberrations are lens errors. It is very difficult to correct purple fringes with software since it is really an overflow of light from one sensor to the surrounding ones, and is not a simple geometric error like transverse chromatic aberration. Also the original color is usually eradicated. Software can thus reduce the color of the purple fringe to a grayish tone. At best the local color is not completely eradicated by the purple fringe and can be reconstructed.
