2e Dust
Up

'Old-fashioned' (paper) photographs sometimes suffer from conspicuous dust. Paint Shop Pro has a filter to correct this problem but as usual the filter should be used with moderation for it also causes the photograph to lose some fine detail. The dust in the following picture (taken in Borneo) is very conspicuous against the smoothly graduated colours of the sunset. 

Choose Adjust > Add/Remove Noise > Salt and Pepper filter - this filter does a remarkably good job. Note that image 'noise' refers to random speckles, not to something you can hear. Play with the settings to achieve the best reduction of dust without affecting my student's lovely profile - try speck size=7 and sensitivity = 4. Switch the preview on and off to see what effect your settings are having on the image.

Don't worry if some defects remain after your restrained use of the Salt and Pepper filter, such as a white vertical line in front of the girl's face, for there is another way of tackling the worst defects: the clone brush.

The clone brush is a very interesting tool, useful in many contexts in addition to this one. The clone brush copies parts of the image into neighbouring parts. You should be able to find the clone brush in the tools toolbar which runs down the left side of your screen by default. If you don't see the clone brush but do see the scratch remover tool then press the triangle next to this tool and switch to the clone brush. A much easier way of selecting the clone brush at any time? Just press 'C' !

Once you have selected the cone brush you need to choose a brush size and shape, then tell Paint Shop Pro where you want to copy from. The tool's option bar should be open now - I suggest you choose a circular shape with size 10. Alternatively, click the button  and choose the shape '+ round 10'. Another simple way to change the brush size is to Alt-Drag i.e. hold down the Alt key and drag the mouse. Try it! To tell the programme where to copy from you will 'Shift-click'. Try that now by Shift-clicking the girl's nose (i.e. hold down the Shift key and click her nose). Now move to some other part of the image and start using the brush - you will find that you are copying her face to the new location! That helps us understand how the brush works but we don't really want an extra face in the picture so undo what you just did with Ctrl-Z.

Now locate a defect somewhere in the picture, such as the white line in front of her face, hold down the Shift key and click about 1cm left of the defect. Then release the Shift key and click or 'paint' across the defect. As you do so, you will be cloning (copying) a part of the image 1 cm left of where you 'paint' since this is the relative position that you pre-defined by Shift-clicking. Of course, you do not have to copy from 1cm to the left. You can copy from above or below or anywhere - it all depends on the relative positions of the Shift-Click and the subsequent click or drag. This tool is a little tricky to master, but it's well worth persisting. When you've done your best at removing the defects from the above image, save it and continue below.

Now that you have had some practice with the clone brush, try using it to turn this photo from Bali, Indonesia...

into this...

First, of course, you'll have to find the two differences between the two images... I cheated a bit and made use of the sharpen tool as well as the clone brush. This might also be a good time to try the smudge tool , but I think you'll find the clone brush more satisfying to use. The sharpen tool and smudge tool can be found in the tools toolbar but may be hidden e.g. under the dodge tool .

As usual save your work when you're done.
