Photograph Guidelines

When working with photographs – there are several concepts to remember if you are taking your own pictures.Just because you can google an image and save it, doesn’t mean it is ok to use it!Phone quality is catching up with what the high-end DSLRs (Digital Single Lens Reflex) are capable of.

Photograph Guidelines

Rule of Thirds:Assists with making the design/layout of a space more interestingNote our Goat– 1/3 of the left, 1/3 downWe call this location a Power Point

Photograph Guidelines

Leading Lines:Creates visual guides our eyes will followWe normally like to follow from the left to the right

Photograph Guidelines

Try to obtain an odd number of objects (3, 5, etc.)Keeps the design more interestingMake sure the layout of the frame makes it clear what the subject is.Example – What is the ‘subject’ of the image to the left?

Photograph Guidelines

Do NOT Crop on a Joint!It can ruin a good shot/photographAlso confuses our eyes and throws the viewer off when looking at your subject.

Making Selections in Photoshop

The Marquees, Lassos & Magic Wand Tools

Making Selections

The first group of 9 tools are used to make selections.In Photoshop, selections are based upon pixels, not objects (i.e. Illustrator)Making Selections in Photoshop requires a selection tool to be used, then the selection is adjusted by adding additional selects or deleting selectionsThese tools can also create safe areas to be colored in as wellWhen you have a small arrow in the lower right corner of a tool, this means it is a collapsed icon. Click and hold over the tool to expand the toolAll Adobe Products work like this. They try and group the similar tools together.

Zoom in or locate your Bath Photograph.Select the Magic Wand Tool (Collapsed under the Quick Selection Tool)

Click in the Bath sky area, up and to the right.Notice the Marching Ants

The Magic Wand Tool relies on

Tolerance

, or the range of pixel contrasts to select.

By clicking on a spot (pixel), Photoshop looks for pixels darker and lighter than the one selected.

Larger the
