How to Photograph a Ghost using free image editing software As it’s halloween night tonight, and I have been requested to publish more image editing video tutorials using the Seashore free image editor for Mac, here’s the latest lesson in the series, which should be a lot of fun. It’s called “How to Photograph a Ghost” and will enable you to produce a well executed picture of a ghostly transparent human body against a real background without any noticable edges and even with the perfect shadow effects. As this is tutorial number 4 in a series, following on from :-

Image Editing – Layers Image Editing – the clone tool Image Editing – Colour Select

… we do use some slightly more advanced techniques then in the first three image editing with Seashore for Mac videos, but nothing that the beginner cannot master with just a short amount of practice. You can’t use an existing photograph, you’ll either have to go out and take a picture specially in one place, twice, or else you can download and use the two creative commons licensed photographs used as an example in the video. Image Editing Video Tutorial – Seashore for Mac 4 So first watch the video all the way through, then decide on your subject matter:

After watching the video once, you can wind back to the beginning and try copying the same technique yourself using the seashore software. The best thing would be to go out and shoot a similar pair of your own photographs, being careful to hold the same camera position for both. If you do decide to use the example pictures to practice on, you can download them by cmd+clicking the following two thumbnail pictures then selecting “save target as” or else clicking through to the larger pictures then dragging them off to your desktop.

The second video tutorial in this series about image editing concerns the use of the Clone Tool. In the first lesson we looked at image editing with Layers, and again I’m using the Seashore free image editing software for Mac but the same principles apply to many other image editing software packages. Image editing with the Clone Tool Click here to view the embedded video.

One simple use of the clone toolis to extend some background over part of an image that doesn’t fit in, effectively making some obtrusive feature vanish. The limitations to this are that the background has to be something relatively uniform. If you want to try your hand at editing the photograph used as an example in this tutorial then you will find it here on Flickr with a creative commons license that allows derivatives to be made and published, with attribution.
