Clean a Camera Lens Tips

For taking high caliber and spotless pictures, the camera focal point requires normal cleaning. Cleaning is likewise a workmanship simply like taking great pictures. On the off chance that the cleaning is done inaccurately then it will most likely bargain the nature of the photos. Focal point cleaning is a standout amongst the most crucial upkeep rehearses. Before beginning the cleaning procedure, it must be comprehended whether the focal points are simple to use sort or the SLR (burn focal point reflex).

Things Needed

Taking after are the things which are required:

– Camera Lens

– Soft brush

– Clean sheet

– Cleaning fabrics which ought to be uncommon materials like the ones utilized for cleaning eyeglasses. Customary towels or materials are not appropriate as they can leave scratches and cushions on the focal point

– Cleaning liquid should be produced using unadulterated water or liquor. On the off chance that this is not accessible then plain water or liquor will be fine.

Cleaning Point-and-shoot lenses

These types of camera lenses are built-in and they normally have a protective automated window and shutter for protecting the glass from scratches and streaks. These lenses don’t often get dirty and regular cleaning is not required for them.
Steps:
1. Turn on the camera for opening the lens corner.
2. Few drops of cleaning fluid are to be poured on the cleaning cloth.
3. The lens is to be cleaned from the outside and inside. All the surfaces should be reached especially with the small lenses.
4. It has to be made sure that the lenses are dry before turning off the camera and engaging the lens cover.
5. Turn on the camera and take a test picture for checking if there are marks or streaks on the photograph.

Cleaning SLR lenses

These types of lenses are mostly preferable for taking outdoor photographs, this is the reason that they can be very dirty. However they are easy to clean as compared to other types of lenses.
Steps:
1. Look for a place that is free from dust and near the window having direct sunlight. Spread out the clean sheet and place all the items on it.
2. If the camera lens is still attached to the body then it has to be removed. Those lens parts that are attached to the body do not require cleaning. It should be made sure that this part is not touched as fingerprints can affect the picture quality.
3. Use a soft brush for gently removing any dust or dirt.
4. Little amount of cleaning fluid has to be poured on the cloth.
5. Start cleaning the lens from the center slowly moving to the outer surface and then wipe off the fingerprints. Straight strokes should never be used as form straight marks that are difficult to remove.
6. The dry part of the cloth has to be used for wiping the lens.
7. Inspect the camera lens under the sun for ensuring that it has been cleaned adequately. Now place the filter on the lens for making sure that there no particles are trapped in between the two.
8. The lens can now be mounted back into place on the camera body.
9. Take a test picture for checking if there are any streaks or marks on the lens.

Color Space in Digital Photography

In this photography online course, we will take in the essential picture parameters in advanced photography and computerized cameras. They are:

Tint, Saturation, Contrast, Sharpness, Tone and Color space.

For better computerized camera picture predominance and for better advanced photography you can control these picture parameters and improve your photography. In any case, you should likewise comprehend that the best choice is dependably to take a photogaph in RAW record choice and change it utilizing picture altering virtual products.

Tweaking features offered by some brands:
Some brands of digital cameras do have some ingrained tweaking features which you may use if you have one of them. Some of these are:
Nikon D300 and Nikon D400 allow tweaking parameters by settings for individual parameters and presets. Konika Minolta A2 has bracketing choices for the image parameters. It allows you take the same picture image using different parameters. Canon EOS 30D allows several tone and saturation settings. Nikon Coolpix P50 and Canon Powershot SD850 IS have the option for lighter and darker skin tones.

The concept of color space:
A color space is a model used by computers to map color, using numbers. Principally, there are two types of color spaces, RGB and CMYK. RGB is also called as additive color space and CMYK is also called as subtractive color space.

Additive color spaces are used on displays and screens, a combination of colors giving appearance to a particular color. Subtractive color spaces are used in printing applications. To get a particular color, another color has to be subtracted from the white substrate so that the reflected light can be perceived to be a specific color.

In additive color space, screen emits a light using a combination of different lights whereas in subtractive color space, the surface of printed paper absorbs all wavelengths except the color that needs to be perceived.

Many dSLR cameras use RGB color space. Before getting a photo printed, it is always a good idea to convert it into CMYK color space so that you may know the exact result you will be getting after it is printed.

Even if you don’t change the color space to CMYK, computer programs do it before printing. Color spaces are defined in computer programs using hue, saturation and brightness as defining guides. RGB model includes HSL (Hue, Saturation and Lightness) and HSV (Hue, Saturation and Value).

Digital Portrait Photography Benefit

Digital photography has turned out to be extremely well known for both expert picture takers and beginners alike. Endless photos can be taken without the stress of squandering film. Undesirable photos can be erased from the camera with the push of a catch. With the rise of cutting edge computerized cameras that are moderate and promptly accessible to general society, pretty much anybody is equipped for taking quality advanced representation photography.

Photo altering programming has the capacity of expelling red eye, modifying the daintiness or obscurity, alongside incalculable different adjustments to photos. Picture takers now have a more prominent wiggle room since defects can be altered by the altering programming. Computerized cameras have mind boggling elements, for example, quicker screen velocities, night and picture modes, and better zoom abilities, which make the occupation of a photographic artist much less demanding.

Tips for Taking Great Digital Portrait Photography

Here are some good tips and tricks that will help you excel at producing digital portrait photography. Try to be sure and provide enough light as to avoid using flash whenever possible. Not only does flash create red eye, it can also reflect off of clothing and jewelry, causing undesirable effects. If you have to use a flash, avoid the blink syndrome by taking several warm-up shots.

This will allow the subjects’ eyes to become accustomed and help reduce the incidence of blinking during the shot. Keep your viewer’s attention focused on the subject of the photograph by using simple backgrounds. Leave plenty of room around the subject by avoiding the urge to fill you frame with the subject. Different sizes of prints often require cropping of the edges and you want to have plenty of room to work with.

Take advantage of the digital cameras faster shutter speed. This is especially beneficial for shooting babies and capturing facial expressions. Engage the subject in a conversation about a topic that pleases them. You are more apt to capture and beautiful, natural expression rather than a forced, rehearsed smile.

A more natural setting for the portrait can make you subject feel more at ease as well as conveying openness and friendliness. Try converting your portraits to black and white to give them a more elegant and dramatic look. Outdoor portrait photography can sometimes present challenges. It is important to research and prepare for the portrait before hand.

Try to have everything set up ahead of time, including lighting, background, props, etc. Digital portrait photography can be very rewarding. Don’t worry too much or be intimidated by it. There is a lot of photograph editing software available that can easily help make corrections and alterations to images.

Taking The Perfect Photography Lighting

perfect-photography-lightingOne of the most serious issues that numerous individuals have when they learn photography is the manner by which to settle the photography lighting legitimately. Individuals that never learned legitimate photography lighting regularly think that its hard to locate the right mix of light to upgrade the look of their photos. Albeit numerous sorts of cameras have light channels and consequently setting flashes, to truly get the best photos, the individual must have the capacity to control the lighting themselves.

Distinctive Types of Photography Lighting

Pass on, the best kind of photography lighting is characteristic light. The light from the sun or the moon can enlighten the protest of the photo so as to make them show up smoother and milder.

Coordinate daylight is a portion of the brightest photography lighting accessible and makes idealize shadows for the foundations of the photos. Characteristic light is likewise utilized as photography lighting inside, by taking the photos close windows and other splendidly lit ranges.

There are many other types of photography lighting that can be used by someone that is interested in taking excellent photographs. Many photographers choose to use directional lighting, which can be placed anywhere around the subject to illuminate them in a specific way by using artificial lights such as flashes or tungsten halogen lamps.

Using a combination of lights to create shadows or focus on a particular area of the image, the person can obtain creative images by changing the direction of the photography lighting.

How to Learn Proper Photography Lighting

Most photographers learn the techniques of photography lighting by trial and error. Different combinations result in different types of illumination and shadows, so it is important for the photographer to find a lighting technique that they like. This method is the least expensive way of learning photography lighting.

Some cameras have different lighting functions that can be used for different situations so that the photographer does not have to worry about setting the lighting each time. This helps create the perfect lighting for different photographs without using additional flashes or lighting equipment.

The direction that the photography lighting is facing is just as important and should be modified to place the subject in the best light possible. When taking portrait photographs, lighting should be at the back of the subject to soften the facial features and hide any minor imperfections in the skin.

Digital Photography ISO Setting

What is ISO?

In traditional (film) photography ISO (or ASA) was the indication of how sensitive a film was to light. It was measured in numbers (you’ve probably seen them on films – 100, 200, 400, 800 etc). The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking.

In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.

Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports event when you want to freeze the action in lower light. However the higher the ISO you choose the noisier shots you will get. I’ll illustrate this below with two enlargements of shots that I just took – the one on the left is taken at 100 ISO and the one of the right at 3200 ISO (click to enlarge to see the full effect).

100 ISO is generally accepted as ‘normal’ and will give you lovely crisp shots (little noise/grain).

Most people tend to keep their digital cameras in ‘Auto Mode’ where the camera selects the appropriate ISO setting depending upon the conditions you’re shooting in (it will try to keep it as low as possible) but most cameras also give you the opportunity to select your own ISO also.

When you do override your camera and choose a specific ISO you’ll notice that it impacts the aperture and shutter speed needed for a well exposed shot. For example – if you bumped your ISO up from 100 to 400 you’ll notice that you can shoot at higher shutter speeds and/or smaller apertures.

Questions to Ask When Choosing ISO

When choosing the ISO setting I generally ask myself the following four questions:

  1. Light – Is the subject well lit?
  2. Grain – Do I want a grainy shot or one without noise?
  3. Tripod – Am I using a tripod?
  4. Moving Subject – Is my subject moving or stationary?

If there is plenty of light, I want little grain, I’m using a tripod and my subject is stationary I will generally use a pretty low ISO rating.

If it’s dark, I purposely want grain, I don’t have a tripod and/or my subject is moving I might consider increasing the ISO as it will enable me to shoot with a faster shutter speed and still expose the shot well.

Of course the trade off of this increase in ISO will be noisier shots.

Situations where you might need to push ISO to higher settings include:

  • Indoor Sports Events – where your subject is moving fast yet you may have limited light available. 
  • Concerts – also low in light and often ‘no-flash’ zones

     

  • Art Galleries, Churches etc- many galleries have rules against using a flash and of course being indoors are not well lit.

     

  • Birthday Parties – blowing out the candles in a dark room can give you a nice moody shot which would be ruined by a bright flash. Increasing the ISO can help capture the scene.

ISO is an important aspect of digital photography to have an understanding of if you want to gain more control of your digital camera. Experiment with different settings and how they impact your images today – particularly learn more about Apertureand Shutter Speed which with ISO are a part of the Exposure Triangle.
