Photoshop basic tools
Opening a file
- Option #1 - Choose File >Open and navigate to find your file.
- Option #2 - You may drag a file's icon into a blank Photoshop window to
open it.
Cropping a file
- Choose the crop tool on the left-side toolbar and drag out a bounding
box. You may rotate a picture while cropping too. Tweaking the size is
possible using the crop box handles.
Zooming In and Out
- Use the Zoom tool (magnifying glass icon) and click in the picture to
zoom in. Option-click to zoom out.
- Press Command + (plus sign) to zoom in, press Command - (minus
sign) to zoom out.
Toning Lights and Darks, but not colors
- Use Image > Adjustments > Levels (can be used for color too, but not as
powerful as the next method)
Toning Lights and Darks, and Colors
- Use Image > Adjustments > Curves
Dodging and Burning (three options)
- Dodge and Burn tools - Use the dodge and burn tools in the left side
toolbox. The dodge tool looks like a lollipop shape, burn tool looks like a
hand w/ opening after their darkroom counterparts. Be sure to change the
"Exposure" slider on the Options Bar at the top to about 10-20%. The default
of 50% is way too strong.
- Lasso tool - Use the Lasso tool in the toolbox (3rd down) to select an
area, then choose Select > Modify > Feather and specify a pixel value (more
pixels = gentler feather), then run Image > Adjustments > Levels.
- Quick Mask gradients - For gently feathered burning of corners, it's
hard to beat a selection made in Quick Mask mode, then running a Levels.
Steps are: Double click the Quick Mask button just under the
foreground and bsackground color swatches in the toolbox. The dialog choice
should be Color indicates: "Selected Areas", then click OK to start work in
Quick Mask mode. Choose black as the foreground color and white as the
background color in the toolbox swatches. Choose the Gradient Tool, and drag
a selection. If the gradient on the Options Bar at the top shows Foreground
to Transparent as a gradient choice, you may select multiple corners at
once. A red overlay should be seen on all selected areas. Return to Normal
mode by clicking the Quick Mask button once again, and the painted areas
turn into the typical marching ants selection. Run levels or curves to
lighten or darken, then deseclect (Select > Deselect)
Rotating a Picture
- Rotate when cropping a picture. It attempts to keep as much of the
original picture as possible
- Image > Image Rotation - Use either the presets for 90 degree
increments, or choose Arbitrary and work with degrees
- Select All, then choose Edit Transform to rotate freehand.
Spotting out Small Flaws
- Spot Healing Brush - Choose the Spot Healing brush tool from the
left-side toolbox 7th position down). You may have to click and hold on the
icon to display the choices that include the Spot Healing Brush tool. Merely
click on the flaws in your picture to fix them. There will be certain
situations where this won't work.
- Clone Stamp tool - icon looks like a rubber stamp. To fix a flaw, choose
the tool, then Option click in the picture where an area matches what should
be in the flaw, move the icon to the flaw, and click-drag. Don't drag over
long distances or you'll get ugly repeating artifacts.
- Patch Tool - nested with the Spot Healing Brush tool. Works on larger
areas needing work. Choose the tool, circle an area with the flaw like you
are making a selection around it, then click in the middle of it and move it
to a similar area without flaws. Works about 80% of the time.
- Healing Brush in Pattern mode - Create a new 64x64 pixel file and fill
it with 50% gray (Edit>Fill, Contents ->50% gray). Select all of the
64-pixel square picture (Command-a) and choose Edit>Define Pattern.
Choose the Healing Brush tool. On the Options bar at the top, click on
Source: Pattern, and choose the gray square pattern that you just made. On
the Options bar, choose Mode: Screen instead of Normal.
Now switch to the picture to be retouched. Merely brush the tool over skin
imperfections and they will be smoothed substantially. Be careful when
retouching next to dark hair, etc. or the the tool will blend in some of the
darker colors.
Resizing Pictures
Image > Image Size.
This can get fairly complicated and you can resize a picture one of two
ways:
1.Resample Image unchecked: This way keeps the original number of pixels
without altering them, and you merely stretch or shrink
the existing pixels. If they are stretched too large, they will be visible.
2. Resample Image checked: This way will add or subtract pixels to the picture. This is very
useful to cut down very large camera files to smaller pixel dimensions for a
web page. However it's difficult or impossible to upsize a picture without
some uglies showing.
Each of these two methods will require some basic understanding about the
structure of digital pictures in Photoshop. I have a web page
here that gives a
basic background about it.
Non Destructive (Reversible) Toning using Layer Masks
- With a picture open that needs toned, find the Layers palette. Click the
little black/white circle at the bottom of the palette and choose Levels or
Curves, or any of the other options. This does the toning with a Layer
"overlay" and
does not directly change the pixels in the picture - unless the layers are
flattened together. Only a couple of file formats are capable of saving files with
adjustment layers (Photoshop *.PSD files, TIF files). If the layered file is
saved as a JPG, it will be automatically flattened, individual pixel tones
will be altered, and you'll lose the
ability to tweak your toning changes.
Making an Easy Panorama
- Shoot overlapping pictures while you pan a scene. In Bridge,
shift-select all the files you wish to use, and choose Tools > Photomerge.
Click the Reposition option, and click OK.
A Fun Silhouette Effect
- Make a photo of a nice sky with clouds (in lab, use cloudsupsz.jpg)
- Make a silhouette of someone against a white background
- Have both photos open as separate files in Photoshop
- Tone the silhouette photo to remove most intermediate shades of gray
(Image > Adjustments > Levels)
- Resize the silhouette photo to match the pixel dimensions (ignore print
dimension in inches for now)
- Copy the silhouette photo (Select > All, then Edit > Copy)
- Switch to the sky picture and paste the silhouette on top as a layer
(check the Layers palette to see if this indeed happened)
- In the Layers palette, click the Mode list, and choose Screen instead of
Normal.
