Learn Photoshop Now - An Overview of Adobe Photoshop CS4

It appears that Adobe products are getting better and better. CS3 brought us new features such as non-destructive smart filters, quick selection, 3D compositing, enhanced RAW image processing and HDR support.

Adobe’s new software, Creative Suite 4, is intended to meet special challenges such as effective collaborations between designers and developers, embracing new media, reinventing publishing and embracing the explosion of connected media. Chad Seigel, Group Manager for Creative Suite has been quoted as saying, “Adobe is trying to break barriers and integrate all products.”

Changes to  Photoshop  CS4 include an improved interface with the entire application enclosed in the frame which means dual monitor users can have more than one application running. The workspace switcher is for swapping between applications such as Camera RAW 5 and Bridge.

Other welcome enhancements include zoom ratio which is less likely to show jagged or pixelated lines and also possesses a flicker free zoom. Now you can rotate the canvas without jagged lines and the brush size can be previewed directly on the document. Now when the tool is placed over the image it can be moved in size and you can preview it before you use it.

Another tool that has been improved is the Dodge/Burn tool, now when you’re adjusting the shadows, midtones or highlights the tool won’t impose on the other two. When adjusting the saturation on the sponge tool it won’t move out of acceptable gamma.

Adjustment has a dedicated window with all the tools found in the area such as levels, curves, brightness & contrast and exposure. The preview window is in the tab instead of a new window that overlaps the image. This means your picture can be viewed in its entirety and as an added bonus tools such as curves can be adjusted directly on the image for localised amendments.

The icons have been simplified for well-organized use; now you can see what you need to use much faster than before.

The mask panel allows you to choose an area which can be manipulated and even inverted which is good for selective color images.

A feature I really like is content aware cropping. The feature works by first masking the areas you wish to retain in the picture. The image can then be resized and the parts that are protected won’t be cropped into. The program will start to remove areas in between which is an amazing feature to see and use.

An improved blend layer mode has been added and is great for techniques such as focus stacking. The program adjusts the exposure and color automatically so there’s no need to mess about first.

The images must be loaded in as layers and highlighted. Once you have done that click on Edit>Auto blend layers and the images will be composited together. The process can take some time so be patient.

It can also be useful to create HDR images if you prefer the ones without the ethereal effect that most systems produce.

Bryan Hughes,  Photoshop  Product Manager, is adamant that this isn’t a HDR tool though, as it doesn’t give a full high dynamic range in all areas so the familiar ethereal look of a HDR image is absent. He did add that if need be, it could be described as a clipped version of HDR.

The Extended version of  Photoshop  CS4 also features support for 3D. Two dimensional images can be changed to 3D by giving them x, y and z co-ordinates and these images can also be wrapped around imported 3D images.  Photoshop  CS4 also works in conjunction with Google 3D warehouse where you can import thousands of 3D images. Merging a 2D image onto a 3D image is simple as the only command you need use is the Merge button. The 2D layer acquires all the 3D attributes such as decay detail, color and reflections. The 3D image can be manipulated as well and you can also enjoy features such as creating cut-outs, adding detail or changing colors to the interior of the cut-out.

As an added bonus, a feature has been added for help with people who are colour blind. Colours in  Photoshop  CS4 can be adjusted for true colour blindness.

One feature missing in CS4 is the quick tools from the image window bar. When you’ve opened an image, right clicking on the header bar has brought up five options of duplicate, image size, canvas size, file info for metadata and page set up. I often used these, especially file info, and to find it’s not there has added time to my workflow.

At the press release for  Photoshop  CS4 I was bursting with excitement when I saw the features it could do. The newest features such as the auto blend and content aware croping feature are astounding. I also enjoy using the localised adjustments on Lightroom 2 so it’ll be really beneficial on  Photoshop  CS4.

Look at the noted upgrades box and see if you’ll use all those extra features. Add to that the efficient zooming and 89 percent less drag on the mouse making it move across the screen faster.

Bear in mind that the list is for the Extended version which supports the 3D applications. If you don’t need those then don’t bother with Extended but as far as I’m concerned this new version is the best one yet.
