26/50 – Improved Image Size and Smart Sharpen Technologies in Photoshop CC

The video below demonstrates two new technologies in Photoshop that can help you to get the highest possible quality out of your image. The first is found in Image size where you can not only expand the preview but also utilize the new edge preserving algorithm when you select the Preserve Details (enlargement) option for Resampling. Note, this option is also used when the image is upscaled and the Resampling option is set to Automatic. The second technology refines the way that we sharpen images using the Smart Sharpen Filter. Notice the reduced noise in the image, especially in the shadow areas as you compare the current technology to the legacy algorithm (tap the “L” key to toggle between them).

24/50 – New Image Sizing Options in Camera Raw in Photoshop CC

There are two choices in the Image Sizing area of the Workflow Options in Camera Raw that I didn’t understand the difference between: Width & Height and Dimensions. Well, thanks to Eric Chan, now I know!

• Width & Height: One would use this option to resize using both the image width and height. The width of the resized image will be limited to the unit specified in the “W” field, and the height of the resized image will be limited to the unit specified in the “H” field. It’s like you’re setting a bounding rectangle for the image to fit inside of (while maintaining the aspect ratio of the image).

• Dimensions: This option is similar to the “Width & Height” described above, but it disregards the image orientation. That is, the longer edge of the resized image will be limited to the larger of the two specified units. Similarly, the shorter edge of the resized image will be limited to the smaller of the two specified units.

In addition, when changing image size, a new option to change based on Percentage is available in the drop down menu.

21/50 – The Crop Tool, Workflow Options and Image Size in Adobe Camera Raw and Photoshop CC

The Crop tool’s behavior has been modified so that it is now solely responsible for defining the aspect ratio of the image and the Workflow options are responsible for determining the actual image size. For example, in order to create an image that is 8 x 10 inches at 300 ppi, click and hold the Crop tool to select 4 to 5 from the list of aspect ratios and crop  the image as desired. Then, using the Workflow Options (accessed via the blue hyperlink at the bottom of the Camera Raw window), check the Resize to Fit option. Select Short Size from the drop down menu and enter 8 inches and a resolution 300 ppi. See how it works in the video below:

Shortcut – tapping the “X” key when using the Crop Tool toggles the aspect ratio from landscape to portrait and vice-versa.

Image Sizing Workflow Options in Camera Raw 8.2

So now we all know. Thanks Eric.  : )

Cropping Images in Adobe Camera Raw 8.1 with Photoshop CC

The Crop tool’s behavior has been modified within Camera Raw 8.1. The Crop tool is now solely responsible for defining the aspect ratio of the crop and the Workflow Options are now responsible for determining the image size. For example, in order to create an image that is 8 x 10 inches at 300 ppi, click and hold the Crop tool to select 4 to 5 from the list of aspect ratios and drag the crop in the image as desired. Then, using the Workflow Options (accessed via the blue hyperlink at the bottom of the Camera Raw window), check the Resize to Fit option. Select Short Size from the drop down menu and enter 8 inches and a resolution 300 ppi.

Scaling Layer Effects and Styles

Selecting Image > Image Size and changing the size of the image will scale the Effect/Style (as long as the Scale Styles option is checked), keeping the Effect/Style in proportion to the layers to which they are applied. However, when using Free Transform to scale an individual layer that has a Layer Effect/Style applied to it,  it will not scale the Effect/Style. To scale the layer style, note what percentage the layer was scaled using Free Transform and then enter that value in the Layer > Layer Style > Scale Effect dialog box. Or, before using Free transform, convert the layer to a Smart Object and resize.

LR3 – Aspect Ratio and Pixels

Don’t forget that in Lightroom you aren’t committing to a specific output size when cropping. Instead, you specify the actual number of pixels that are going to be created when you use the Export feature or one of the Output modules (Slideshow, Print or Web) to create a raster (pixel) based image.

LR3 – Aspect Ratios for Cropping

While using the Crop tool, you can select from the list of default/preset aspect ratios, or choose Enter Custom from the list and create your own. Lightroom will save the last 5 custom aspect ratios entered.

In addition:

• “X” flips the crop (horizontal to vertical).

• “A” will lock or unlock the aspect ratio.

Changing Height and Width Values

In dialog boxes referencing width and height (New File, Image Size, Canvas Size, etc.) if you change units of measurement for one of the dimensions Photoshop will automatically match the units for the other dimensions (i.e. if you select pixels as the units for width, Photoshop automatically changes the height to pixels).  If you need to enter in two different units of measurement, holding down the shift key will override this feature to allow different units for each value.

Resizing Images in Photoshop

When using the Image Size dialog box in Photoshop, there are several different resampling options including those used most by photographers — Bicubic Sharper, Bicubic, and Bicubic Smoother. These different options have an impact on the perceived sharpness & smoothness of the resulting image. When changing image size relatively small amounts (say scaling up or down less than 10%), it may not be necessary to change the default setting of (Bicubic), but when making large changesbe certain to choose the appropriate option for the maximum quality. For example, if you have a high resolution scan and need a low resolution version to place on the web, make sure to use the Bicubic Sharper option. If you have a low resolution capture from your phone and want to resize it to print as a poster, use the  Bicubic Smoother option.

Resizing Images in Adobe Camera Raw

If you are going to need to resize a photograph significantly larger or smaller than it was originally captured, it is better (in theory) to use the Crop tool and the Workflow options in Adobe Camera Raw to interpolate up (resample) the photo as oppose to opening the file in Photoshop and then using the Image Size command to interpolate. This is because ACR does its resampling adaptively, based on the difference in size between the original image size (e.g., 5616) and the target image size (e.g., 2096). So, although there will be slight differences between the two images,  (one from ACR, the other from PS) in many cases, it would be very hard to see the difference to the naked eye. The main difference, then, in practice, is the convenience and the workflow. (Thank you Eric Chan for this information!)

Making Files Smaller

When a layer is larger than the canvas size (maybe you dropped a larger file into a smaller composite), Photoshop keeps track of the information beyond the visible canvas. This provides added flexibility if the image needs to be repositioned. However, when working with really large files (for example when I create my digital illustrations, each layer is 24 x 24 inches at 300 ppi and the files often reach greater than 1.5GB very quickly). In order to keep my file size down, as soon as I am certain that I will not change my mind and reposition the image, I choose Select > All and then Image > Crop. This crops any extraneous information beyond the visible canvas size (which is typically significant for my images as I photograph in a 2:3 aspect ratio but my final images are 1:1). Of course you do loose some flexibility so make sure that you are happy with each layer’s position before cropping!

Resizing Images Using Open Documents

To make a document the same size as another open document, while in the Image Size or Canvas Size dialog box, select the other open document from the bottom of the Window menu (PS will automatically fill in the values).
