Difference in Megapixels Explained with Sample Images

Having a single number with which to judge the quality of a camera may make choosing your desired camera seem like a simple task, but only looking at the Megapixel resolution can be misleading. A Megapixel is the resulting number from multiplying how many pixels wide an image is by how tall it is. For instance, an image that is 2048 pixels wide by 1536 pixels tall contains 3,145,728 total pixels, or roughly 3 Megapixels (2048 * 1536 = 3,145,728). This purely the size of the image. There are other factors to consider.

First, the camera can only see the light it receives. If you are looking through the microscope, and the image you see through the eyepiece is dark, then the resulting picture will also be dark, and the fine details in the shadows may be lost (or indistinguishable). Likewise, if the image is too bright, the details in the highlights may be lost. Before snapping the photo, one needs to adjust the microscope to produce an image without either extreme. This means that the more options the microscope itself has to adjust the light reaching the specimen, the more control one has to adjust the image. An image with mostly mid-ranges (not too dark or too light) is easier to edit and observe because the details are still intact.

 

 

Another factor in digital photographs is the PPI, or Pixels Per Inch (also called DPI – Dots Per Inch) it has. This is the resolution most people are really thinking of when they use the word “resolution”. The size of the image is represented in Megapixels, while its actual resolution is represented in PPI. The PPI is equal to the total number of pixels present in one square inch of a photograph. This is mostly important when an image must be printed, but there are some things you should know about what happens when you resize an image to post on a website, or view on any computer screen. Most often, printed images are 200-300 PPI, whereas images meant for online use are 72 PPI. This means that images online are usually less detailed than the images one sees in a magazine ad of the same size. Let’s say that you post a picture called “Image_One.jpg” with a PPI of 300 next to a similar picture called “Image_Two.jpg” that has a PPI of 72. With all other factors the same, the only way you can tell the difference between the two is by how long it takes to download each. Because “Image_One.jpg” contains more data in the same size area as the other picture, it will take longer to download. For this reason (and others not related to this discussion) pictures are downgraded before posting online (or they are downgraded later automatically by your browser). This is where having a larger Megapixel count can come in handy. Have you ever noticed that when you take a picture, and print full size on a 8.5″x11″ page it looks fuzzy? The rule of thumb in digital photography is that you can always make an image smaller and maintain detail, but you cannot blow a picture up in size and expect the same quality. If you were told by a teacher to write a book report that was 10 pages long, and you only read the cliffnotes, it might be very hard to expound on that limited information enough to meet the page requirement. If that report’s length were changed to 100 pages, and all you had were the cliffnotes, you might be in for a long night(s). In that case, it would be better to have the entire book.

Look at the images below. Both are the resulting images from the same section of the same slide, but the one on the left is taken from the MA88-130 (1.3 Megapixels), and the one on the right is from the MA88-300 (3 Megapixels). They were both cropped and resized down to 300 pixels wide. The image on the right maintained its color and detail but the image on the left loses detail in the shadows and highlights, even after resizing it to be smaller. The size of an image is not the only factor which may determine the image quality, but larger sizes help an experienced photographer in a big way.

 

 

In conclusion, you need to think about what you are going to be using the camera for. If you are one who knows how to edit images and resize them (go to www.photoshop.com for a free online editor) then having more pixels to play with is better for your arsenal. However, if you do not care as much about fine details, and want to quickly email photos of specimens with the only editing of the image being done before taking the picture (by adjusting the microscope) then you can squeeze by with our lower resolution MA88 cameras.
