Movement or moving object photography

Keep your hands and camera steady while taking pictures, use a tripod if possible or lean against it, use more shutter speed, and use image stabilization. Have you ever wondered the opposite? Deliberately move the camera while taking pictures. In photography, its name is Movement Photography.

The key is to use less shutter speed to get more exposure. Move the camera while the shutter is open. Places of light will create a kind of dynamic light path.

Image stabilization in photography

How important is image stabilization in digital photography?

Image stabilization is a common term for modern cameras. This arrangement gives the opportunity to take good, clear pictures. Learn the details of image stabilization.

When you take a picture, the sensor lights up as long as the lens cover is open. At this point, if your hand is cupped then the front view spreads a bit instead of staying in the same place. The picture is blurred as a result. 

The lower the shutter speed, the more likely it is to blur. Again, when a distant image is taken, even the slightest movement covers a large distance, where the image is more likely to be blurred. The solution to this problem is image stabilization.

Basically, the work that is done, this technology of the camera calculates the movement of the camera. The camera stops receiving light from outside as it moves. As a result, the scene of the changed place is not captured, and a clear picture is available.

How the camera does this is a technical matter. Maybe even if you don't know the details.

Image stabilization can be of different types. Which camera adds this technology to the lens, which camera's processor does this, and which camera has two types of systems? The main two parts are optical image stabilization and digital image stabilization. Image quality is good in the optical method.

The stabilized lens has a switch to turn this system on and off. Very easy to use. Turn the switch on to use stabilization, turn it off if not in use.

It may seem that the issue of off is coming, why? Where is the problem if you always keep it on?

If the stabilization is on when you use the tripod, the camera assumes you need to use stabilization. As a result, it tries to stabilize the still image. It produces bad fruit instead of good.

In the case of compact cameras, the on-off stabilization is done from the menu.

So far the word stabilization has been used, but the camera maker uses a different name for it. Nikon is called Vibration Reduction (VR), Canon is called Image Stabilization (IS), Tamron is called Vibration Control (VC), and so on.

In general, the general rules for the use of stabilization

- Do not use stabilization when using a tripod. Always use the other.

-In the case of an SLR camera, switch off the stabilization before turning off the camera.

-When buying a camera or lens, see if there is stabilization (of course, the price of the lens with stabilization is higher).

-Use a tripod if there is no stabilization system or try to keep the hand as still as possible.

-Stabilization can be used to double the normal shutter speed. Use it when taking pictures in low light.

Image Optimization Tips: Alt Tags and File Names

How to Optimize Images for Better Search Engine Rankings

Visitors may love images, but computers don't. Computers are designed to do what you tell them without violating any of the parameters. When web crawlers come across images on a website, they really don't know what to do with it because they are made to collect information, not interpret it. The solution to this problem is to optimize images and appropriately label your alt tags. so that they display the correct content when someone goes to look for it.

For example, let's say you upload a picture of your dog, and label the "alt" tag by the dog's name, 'Frank'. The web crawler is going to read the alt tag without ever realizing it's a picture of a dog; therefore, the crawler will come to the conclusion that it needs to display the image when someone run a search for 'Frank'.

The minor word choice mistakes may not affect the operations of your website, or how your image is displayed, but it will affect the search results of others and the traffic that comes into your website. Whereas you may have been able to attract the dog lovers in the world using image optimization of your dog tagged 'dog', you are now drawing in crowds searching for their uncle "Frank".

To include the alt tag, simply add <span style="color: #0b5394;">alt="this is your alt text"</span> to your image tag. Here's an example:

<blockquote>&lt;img src="pug-dog.jpg" <span style="color:

<img src="pug-dog.jpg" alt="frank dog"

But you don't have to touch the html code of the image. Once the picture is uploaded, click on it and you will see the "Properties" setting. Add the alt text inside the box and hit OK:

This goes the same for file names on a website. You need to optimize images and file names on everything that you decide to save to your website directory so that this information can be appropriately indexed and be used as a search term. You could name the file of your dog Frank, "pug-dog.jpg", which would encourage the search engine to add Frank into searches being performed with the phrase 'pug dog'. Alt tags and file names play an important interpretation role between you and the machine that makes your blog possible.

The Best Tips to Image Optimization and Boost the Website Traffic

People often overlook the importance of images in SEO. In fact, aside from standard search, image search is another fast growing vertical search in the web. Image search is way more popular than blogging, news, shopping, and many others.

Image search has become even more essential because images are being utilized and incorporated in the regular search results of search engines as a strategy to produce more relevant results.

Here are some ways to optimize your images and get a higher website ranking:

Make your file names clear and brief.  Do not use unnecessary, irrelevant words like 'or', 'and', 'thus', etc. They make your content long and complex. These might even cause the reader to lose interest in your content. In the search results, you will see the file name below the graphic image.

Use ALT tags. Search engines also give importance to ALT tags in determining website rankings. The text provided in these tags is indexed by Google. The ALT tag also appears when the user moves his cursor over the image.

The ALT tags should best describe your image. It should also be brief and simple. For an image of a decorative text, simply use the same text in the ALT tag. For an image of bullets, leave the ALT tag blank. Also, use a maximum of 2 to 3 keywords in your ALT tag.

The ALT tag is very helpful in situations where various web browsers display an image differently and some browsers cannot display that type of image.

Develop unique images. This way, web crawlers can differentiate you from the rest of your competitors.

Image Optimization

Finally, add images to news articles and press releases. This boosts their appeal to the audience. You can also add your URL to your images. This way, news outlets might be encouraged to link your website images. So, start linking your images to relevant articles and boosts your website's internal links and traffic.
