Photo-editing software opens up many options for manipulating digital photographs and drawings. The sky is the limit with this kind of creative software. You can develop art in this medium, touch up personal photographs, add various effects, and manipulate lighting. Some photo-editing software is highly complex, as they’re created for image-editing professionals, but there are many programs with good interfaces that allow even inexperienced users to work on them with relative ease. Good photo-editing software will have well-constructed help sections and wizards to guide you through the various components. There are many different photo-editing programs available which range in price from free to hundreds of dollars.

There is a wide array of photo-editing software out there from very simple computer programs to highly complex ones. A simple program may only have options like cropping and basic photo manipulation, while more complex software will have seemingly endless options for modifying pictures. Here is a list of some of the options that you may find:

Cropping – With cropping, you can create a new image by selecting a rectangular portion of the original image. The area that isn’t selected is removed, and the remaining portion becomes the new picture. It does not alter the image resolution. It is typically used to improve the image composition.
Image Size – The size of an image is often recorded in terms of pixels per inch (ppi). An option to change the image size allows you to manipulate this value. Expanding the ppi too much will result in an image with poor resolution.
Color Quality – The coloring of an image can be manipulated in a number of ways. The balance of the colors can be improved with certain tools so the image has more intense coloring. It can correct problems that originated with improper camera settings.
Color Change – Some programs will offer the option to change a specific color or color range within the image. In this process, you select the desired colors to change, and specify a new color to replace it throughout the whole image.
Brightness – This tool can make the image brighter or darker, depending on your preferences. It is useful if you have pictures that are underexposed. There are also advanced techniques incorporated into some software to change the brightness of only some of the pixels that are within a certain range of luminosity.
Sharpness – The sharpness of an image can be manipulated using deconvolution and unsharp masking tools. This can improve the apparent focus of a picture. Alternatively, it can be used to blur portions of the image to draw attention to the subject.
Perspective – Some photographs have a distorted perspective due to the angle at which the picture was taken, and the camera lens. A perspective control tool can fix this problem, although it takes some care, as you could lose some image definition in the process.
Orientation – This option allows you to rotate the image in any direction, and to any degree. This is useful to correct photographs that weren’t taken level with the horizon. Rotating the picture a few degrees can fix this problem.
Image Noise – This tool involves a number of different algorithms that can either remove or add noise to the image. Noise reduction is able to remove scratches or dust marks present on a picture. However, excessive reduction in noise will lead to a loss of detail within the image.
Layers – Layers allow various elements that make up the image to be manipulated separately. Separating an image into various parts using layers make the process of image editing more efficient.
Other Effects – The average image-editing software will have a number of tools to alter a picture in strange or interesting ways. This may involve various types of distortion, artistic effects, and the addition of various textures.

When searching for a good photo-editing program, here are some things to consider:

Price – The cost of a given program doesn’t necessarily indicate the quality. There is some good software available at a low price, and some costly software that is difficult to use. When searching for a good program to manipulate your images, it’s best to focus on whether it will meet your editing needs or not.
Image Formats ‘- Digital images are stored in various formats. Good photo-editing software will at least support the main types, including BMP, GIF, JPG, TIF, and PICT. The more kinds it supports, the better.
Editing Capabilities – This part is up to you. If you’re satisfied with basic photo-editing options then that is right for you. Otherwise, look for some of the editing options listed in this article, and others that you desire.
Help and Support – There should be a good help section with the program, so you can navigate the various options with ease. It’s also beneficial if the vendor has email or phone support available.

Choosing The Best Hard Drive

September 11th, 2011

Almost all personal computers today contain hard drives, generally with many gigabytes of storage space. Hard drives are able to store a lot of information permanently using electromagnetic surfaces to record digital data. You can write on them and rewrite on them, which is what makes them so versatile in computers. It holds records of characters in text files, pixel coloring in images, and executable programs for software. It’s what makes storing programs, music, photos, and other items possible. There are many different kinds of hard drives available, and it can be difficult to choose between them all. Here’s a breakdown of the different aspects that you should consider.

Storage space

These days, you can get a reasonably inexpensive hard drive with about 250GB, which is plenty for most people. However, paying a bit more can get you a lot more space. It depends on your needs. If you plan to install many large programs, or have large music or video collections, think about getting a hard drive with more space. You can also compare cost per gigabyte for various sizes. You’ll find that you usually pay less per gigabyte if you get a hard drive with more storage space. You don’t want to end up getting a hard drive with limited space if you plan to use it up quickly. It’s more efficient to spend a little more initially, so you don’t have to go to the trouble of upgrading later.

Motherboard specification

There are a few different types motherboard controllers that you’ll find in the standard personal computer. These give you the ability to connect your motherboard to various types of storage devices, including hard drives. Serial ATA (SATA) and Parallel ATA (PATA) interfaces are the two main types. You can look for information about connection capability in your computer manual, or by physically checking for the ports. Motherboards with SATA connections use a hard drive with SATA specifications. Likewise, those with PATA connections require a PATA hard drive. Sometimes, you’ll find that the motherboard supports both forms. In that case, you can use either a SATA or PATA hard drive, although most people choose SATA, as they tend to be less expensive and access data more quickly.

Performance

Rotations per minute (rpm) influence a hard drive’s performance, i.e. how fast the hard drive can read or write digital information. A hard drive with a higher rpm will perform better. Most old computers will be fitted with PATA hard drives, while newer ones tend to use SATA. A SATA hard drive is slightly better performance-wise, being about 5% faster than PATA. There are also SATA2 hard drives, which perform operations even faster. However, these are usually unnecessary unless you are using a demanding program like a graphic-intensive video game. If you plan to go with a SATA2 hard drive, you’ll probably have to also get new components for your computer so the format is supported. As you’d expect, the faster models are more expensive. The common SATA interface is acceptable for most computer processes.

Physical size

You’ll find several different sizes of hard drives available. 5.25” hard drives were the standard in the past. Today, most computers accept 3.5” hard drives, and notebooks have 2.5” hard drives. If you have an old computer with a 5.25” bay, you can fit a smaller hard drive using special rails. In terms of cable size, the old PATA hard drive connector cables take up more space, as they’re thicker. SATA hard drive cables are narrower, and easier to connect.

Noise level

In general, the faster the rotation speed of the hard drive, the louder it will be. Larger hard disks also tend to be noisier. All hard drives make noises, although different brands have various methods to reduce these sounds. As a result, you’ll find that some hard drives are quieter than others. You should look for notes about how it is designed to reduce these noises when you’re searching for a new hard drive. If you’d find a noisy hard drive annoying, it’s probably worth paying a little more to get a quieter one.

Warranties

Manufacturers often offer warranty periods for their products if sold by authorized businesses. It’s up to you whether you believe extra insurance is worth the extra cost. If you’re buying a hard drive from a discount store, it’s probably more important to get a warranty. If a hard drive crashes, chances are you won’t get your data back anyway. The best insurance is to back up everything on it regularly.

Thinking about these elements of hard drives can help you find the best hard drive for your purposes. Some people are happy with inexpensive small and relatively slow hard drives. Others need more space or faster processing speeds. Choosing the right hard drive for you can seem daunting, but with a little research you can get the best one for the least amount of money.
