Analog vs. Digital Printing

There’s a significant transformation in the printing process when comparing analogue to digital print processes. In analogue printing the points of control are typically quite flexible: You choose and modify – enlarge, substrate, distance to the substrate, light source, exposure duration and filtration (globally and locally), chemistry dilution, temperature, duration of immersion, and agitation (again globally and locally). Frequently, prints are further enhanced after printing. When printing digitally, the points of control are comparatively inflexible. You choose to modify (but...

What are Photoshop Smart Filters?

To work with Smart Filters, you need to work with Smart Objects. When using Smart Objects, Photoshop stores a copy of the original pixels; so, if you make changes to the Smart Object’s appearance by transforming or applying a filter, the original pixel data is still available. If you transform again or change the filter settings, the new appearance is based on the original pixels. For example, say that you create a Smart Object from a photo and you scale that Smart Object to 50%, is the image’s quality degraded? Yes, just as if you had scaled the original photo rather than a Smart...

Creating & Printing Greyscale from RGB Images

There are many ways to create greyscale images from RGB images; however, to create a greyscale look and feel that you want, you must control two aspects of this process: Where and how your RGB is converted into greyscale. Basically, there are two places where your RGB image can be converted into greyscale: You can accomplish the conversion in an image-editing program such as Photoshop, or you can convert your image to greyscale through the printing process. Typically, performing the conversion in Photoshop will provide you with more control, and probably with results more to your liking. However...

Blending In Photoshop

Photoshop Blend modes are used, in conjunction with opacity, to control how pixels on one layer will interact with pixels on the layers below, and how Photoshop’s painting tools interact with colours already on a layer. How do blends work? Blend modes are used, in conjunction with opacity, to control how pixels on one layer will interact with pixels on the layers below, and how Photoshop’s painting tools interact with colours already on a layer. They control these interactions by comparing existing colour to the new colour and calculating the interaction according to the formula...

Warping Effects in Photoshop

On occasion, you may need to apply layer effects to more than one layer but have the layers treated as a single element instead of applying the effects to each individual layer. For example, you could have a total of eight layers that contain simple solid-coloured rectangles that overlap. Warping multiple layers: Choosing Edit>Transform>Warp will allow you to bend a layer into all sorts of interesting shapes. The problems start when you have a complex image with more than one layer selected. The Warp command will only Warp multiple text layers and will be unavailable if more than one...

Some useful Photoshop Tricks

Anti-aliasing, Feathering, use of the Quick Mask and Refine Edge tools are the subjects of this tutorial. Anti-aliasing refines the edge of a curved selection to make it look relatively smooth. Anti-aliasing, like other selection refinements, doesn’t show up in the default marching ants’ view of a selection boundary. To demonstrate anti-aliasing in Photoshop, we need to use a workaround. Anti-aliasing Ask a random Photoshop user what anti-aliasing means and you may get a blank stare. I recommend teaching this topic by creating an anti-aliased selection and then comparing its appearance...

The Fine Art of Inkjet Printing

Today’s digital files need to be high resolution to hold crisp detail and smooth gradation. But did you know that the resolution in digital files and for digital printers isn’t always the same. Taking inkjet printing to the next level Resolution High resolution in digital files and printers is needed to hold crisp detail and smooth gradations, which have become hallmarks of fine photography. Resolution in digital files and digital printers isn’t the same. Resolution for digital files is measured in pixels per inch (PPI); pixels are square and surrounded by other pixels. Resolution...

Photoshop – Quick Tips 4

Part 4 of this Photoshop Quick Tips Tutorial covers: Applying a custom warp Chameleon Keystrokes Smart Objects Things to watch out for when adding layers Workaround Warp Do you sometimes wish that you could apply a custom warp to your live type?

The advantage, of course, is that warping a smart object is not destructive and you can change the type (or the warp) at any time. Here’s how: Open a new blank document, choose Layer>Smart Objects>Group into New...
