As a professional fashion photographer, a DSLR camera is my natural choice, as I am after quality pictures, but the DSLR offers so much more than just quality. The performance and functionality is above any Digicam. A Digicam is great when you are taking pictures just for the heck of it, but you will require a DSLR if you are a professional photographer, or training to become one. So if image quality if your first concern, then I would like to recommend a DSLR.

There are a number of high-end Digicams that offer similar mega pixel resolutions as many DSLR’s do, but the sensor on a DSLR are 4 to 6 times larger than those of any high-end Digicam.

The reason behind my recommendation is because a DSLR offers excellent user-adjustability; and especially in regard to lens aperture.  The lenses are interchangeable, so you can easily cover a range of lengths. It offers a great response time, and the operation process is faster. Furthermore, the ISO setting allows you to take superior photographs even in low light, and much more. If you are not ready for a crash course on how they work, you will be happy to know that most DSLR’s come with an “automatic” feature, where the camera decides the best setting. So there is no need to struggle with various settings, you can simply practice the features on your days off.

The beauty of a DSLR for beginners is that you can choose the “scene” you are shooting for instance, landscape, night shots, portraits, and sporting action. Once you set the scene your camera will automatically adjust itself in seconds. However, before you decide to go out and buy a DSLR there are a few factors you need to take into account. As I will be unable to cover all the aspects in a single post, today I will focus on the influence resolution, and sensor size, has on the image noise.

There are a number of high-end Digicams that offer similar mega pixel resolutions as many DSLR’s do, but the sensor on a DSLR are 4 to 6 times larger than those of any high-end Digicam. Which allows the DSLR to offer higher quality images in comparison to high-end Digicams. Keep in mind that DSLR cameras offer various sensor sizes, but there are three that are most commonly used.

The image sensor is what makes an image higher in quality, the larger the sensor the more capable it will be to capture protons (such as light). This allows a DSLR camera to reproduce images more accurately compared to Digicam. If you take a picture with a Digicam you will see in some situations that images are extremely grainy, especially in dim lighting. This is because the sensor is much smaller in size, and is not able to capture the image perfectly. On the other hand, a DSLR camera will be able to offer you images that are less grainy, and sharper, even in dim light.

Most DSLR’s today come with either a CCD sensor of a CMOS sensor. Both are equally capable of offering good images, but CMOS are preferred as it requires low power. They are placed in high-end professional DSLR’s, because they offer more functionality, apart from the core sensor chip. Which ensures superior light capturing capabilities matched with high-resolution. This allows the photographer to capture everything from shadows to highlights, with smoother color gradations, on point hues, and images with lower noise.
