 | | Understanding Resolution in Adobe Photoshop CS4or designers working ingraphic design companies using Adobe Photoshop CS4, it is important to understand the various resolution-attributes like dimensions, bit depths, and color models. These are discussed below:
The dimension of an image should be set with a proper pixel value. Although, Photoshop has a maximum pixel limit of 300000 X 300000, graphics designers usually prefer to keep the dimension to a lower resolution (for example, 400X400 pixels). Similarly, one can work with bit depths up to 32 floating-point bits per channel in HDR (High Dynamic Range) mode in graphic web design ; although, most image editing is done at 8 bits per channel (24-bit RGB and 32-bit CMYK).
The different resolution types are:
Sampling Resolution - For scanned images, sampling resolution gives a measurement of precision of the scanning process which is measured in sample per inch (spi).
Document Resolution - The resolution value saved in the file when an image is imported from any software, is known as document resolution. The image quality changes only when the image is resampled.
Effective resolution - The effective resolution is the resolution of the image after it is scaled (by compressing or stretching the pixels) to its final print size.
Device resolution - It is the resolution of the output device. In graphic and web design, where the output device is not specific, it is essential to keep the resolution to a common and acceptable figure.
To give details of the resolution of an image, following parameters are important:- Pixel Dimensions
- Physical Dimensions and Resolution
- File Size
- Megapixels
- Single-Side Dimension.
- 'Res' or the number of pixels per millimeter
A bigger resolution does not necessarily mean a better resolution. A higher means that it would take longer to get saved, printed or opened. At the same time, a lower resolution may result in a pixelated image with a degraded quality. So, it is essential for a web graphic designer to keep the right resolution balance depending on the purpose of the final image. |

Ferrell McCollough, a widely respected photographer, pushes the boundaries and inspires others to pursue their artistic vision, too. The amazing results simply can't be achieved any other way. | Words from the Author:
Photography is not my hobby or profession, it's my sweet illness. Each day I hold a camera it becomes a creative journey. I find myself searching deeper to see the essence of my subject. I become immersed in what I'm doing as I experiment and play. I often find it hard to walk away even when I'm done shooting. Of course only a few images are really successful but good or bad, the pictures taken are more about where I went and what I did.
Photography sparks the imagination and fantasy. It brings us closer to knowing what moves us in life. If you've never picked up a camera or if its been a long time, give it a try. Play, laugh, and shoot whatever you like. In time you will learn the strengths and weaknesses of the camera and you will be seeking and crafting images that reflect your moods and desires.
There is a saying, "Dance like nobody's watching" I love the saying because it really is a reminder to enjoy life with uninhibited enthusiasm. Thank you for taking the time, your valuable time, to visit this website. I hope you return now and then to catch up on my latest photos.
