‘The sharpness of the image recorded on your camera is affected by many factors: focus, lens, aperture, shutter speed, raw or jpeg format.

The process of sharpening is done through software tools by increasing the contrast along edges of pixels and enhancing them to heighten image definition. Applying sharpening to your images is both a technical and creative process. It can help emphasize texture and detail and it is essential when resizing for the final output. The difficulty always lies in knowing how much to apply.

Sharpening should be thought of as a multi stage approach within your workflow. There are three stages where a file can be sharpened: Raw Capture, Post-Processing and Output.’

‘So, what is monitor calibration and why is it important?
Monitor calibration and profiling is the process in which you measure the colour gamut of a particular monitor with a colorimeter (measuring instrument) and produce a description of this information in a profile so that applications like Adobe Photoshop can render the colours on screen accurately.’

My second article titled ‘How (& Why) to Calibrate Your Monitor’ for is now live. If you want to find out the hardware and software options in monitor calibration, please read on. The article also gives you the standard monitor calibration settings to achieve compatibility with the creative industry so that What You See Is What You Get.

Image samples with various exposures are included to illustrate the differences in histogram interpretation. In additional, the article also discusses the usefulness of the RAW file format and why one should take advantage of the high dynamic range of today’s image sensors.
