Camera Simulator explains the relationship between aperture, shutter speed and ISO

Aperture, shutter and ISO value – three different parameters that control a single aspect of your camera, the amount of light entering through the lenses or the brightness of the pictures, in terms of the end product. For casual users, these terms are irrelevant since they are more likely to use a point and shoot camera that auto adjusts the aperture and shutter speed for each shot. But to get that perfect shot with just the right amount of light you might have to override the automatic settings and take control over the camera. Most digital cameras, even the point and click ones, allow you to do so.

Camera Simulator gives you an interactive visual demonstration of the relationship between these three vital camera setting. The simulator has three sliders for the three parameter which you can adjust and see it’s effect on a test image.

It let’s you determine the exact shutter speed required for any given aperture value and vice versa. For instance, if you want to shoot a moving object, you will have to increase the shutter speed to avoid motion blur and at the same time increase the camera aperture to allow as much light as possible during the reduced exposure time. The question is: by how much? Camera Simulator will help you gauge it.

Here is another interesting effect. Check the box “link aperture/shutter”, and move any one of the sliders to see how the depth of field changes as the aperture changes at constant exposure. When you move the aperture slider to the left extreme (f/4), i.e., make the aperture small, the depth of field becomes shallow and you can see this by blurring of the far background in the test image.

When you move the aperture slider to the other extreme (f/32), i.e., make the aperture large, the depth of field becomes large and the background comes in focus. But it also prolongs the exposure time resulting in motion blur on the dog. This is very nicely done.

Camera Simulator also shows the effect of different ISO values on a photo. Additionally, a simulated light exposure meter, which high end cameras carry, shows how the image exposure values are set. Very impressive.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.

Diagram 101: Different Types of Diagrams and When To Use Them

Diagrams are a great way to visualize information and convey meaning. The problem is that there’s too many different types of diagrams, so it can be hard to know which ones you should use in any given situation. To help you out, we’ve created this diagram that lays out the 7 most common types of diagrams and when they’re best used:
