Photoshop-Sharpen with the High Pass Filter

 Tonight, I looked at the feature on Photoshop that lets you sharpen the overall tone of an image. This feature is handy for images that look flat and need sharpening. Examples done...

A useful tool that is helpful post to rectify subtle mistakes noticed in images. 

Technical feedback on Printing. 

The following assignment looks at possible mistakes that have occurred in photographs. Some mistakes took place long before the image was created at the printers for numerous reasons.

1. It is important to focus on the correct part of the image you are trying to capture. Meaning, use your focus.

2 Do not focus on the background image-and clean you camera afterwards.

3 Be careful you don't apply to much blur filter.

4 Make sure your lens equipment is not substandard.

5 Try to make sure your subject is in focus and always use Photoshop correctly when cutting images out.

6 Use a tripod and avoid camera shake. 

Over Sharpening 

The root cause of over sharpening is over exposed images. Therefore, try to underexpose your images slightly to compensate. Another way is- create a new layer-filter-blur-Gaussian blur. Select a radius depending on the amount of sharpness in the image, Decrease the amount of blur by altering the opacity and press OK. 

Blending mode to darken "which will make the image soft and the overall sharpness come back to a good level"

Right click on the top layer-where you have applied the effect, click flatten image.

Under Exposed

The main reason for images being under exposed is..

ISO, Aperture and shutter speed incorrect-due to a light meter or grey card not used before the image is taken. Or, no flash used or inadequate lighting used to illuminate the subject.

To overcome this, use a light meter, grey card and use a flash. Make sure you are shooting with enough light.
