During this time, John traveled to Silicon Valley and gave a demonstration of the program to engineers at Apple and Russell Brown, art director at Adobe. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988.
Photoshop files have default file extension as . PSD, which stands for “Photoshop Document. A PSD file stores an image with support for most imaging options available in Photoshop. Photoshop files sometimes have the file extension .
A PSB file extends the PSD file format, increasing the maximum height and width to 300,000 pixels and the length limit to around 4 Exabytes. Because of Photoshop’s popularity, PSD files are widely used and supported to some extent by most competing software. PSD file format can be exported to and from Adobe’s other apps like Adobe Illustrator, Adobe Premiere Pro, and After Effects. Adobe creates some plugins, such as Adobe Camera Raw, but third-party companies develop most plugins, according to Adobe’s specifications. Some are free and some are commercial software. Most plugins work with only Photoshop or Photoshop-compatible hosts, but a few can also be run as standalone applications. There are various types of plugins, such as filter, export, import, selection, color correction, and automation.
Filter plugins can either modify the current image or create content. Alien Skin Software, Auto FX Software, AV Bros.

Photoshop includes a few versions of the pen tool. The pen tool creates precise paths that can be manipulated using anchor points. The free form pen tool allows the user to draw paths freehand, and with the magnetic pen tool, the drawn path attaches closely to outlines of objects in an image, which is useful for isolating them from a background. The Clone Stamp tool duplicates one part of an image to another part of the same image by way of a brush.
The duplication is either in full or in part depending on the mode. The user can also clone part of one layer to another layer. The Clone Stamp tool is useful for duplicating objects or removing a defect in an image. Photoshop provides an array of shape tools including rectangles, rounded rectangles, ellipses, polygons and lines. These shapes can be manipulated by the pen tool, direct selection tool etc. The eyedropper tool selects a color from an area of the image that is clicked, and samples it for future use. The hand tool navigates an image by moving it in any direction, and the zoom tool enlarges the part of an image that is clicked on, allowing for a closer view.
Selection tools are used to select all or any part of a picture to perform cut, copy, edit, or retouching operations. The crop tool can be used to select a particular area of an image and discard the portions outside the chosen section. This tool assists in creating a focus point on an image and unnecessary or excess space. Cropping allows enhancement of a photo’s composition while decreasing the file size. The “crop” tool is in the tools palette, which is located on the right side of the document.
The “slice” and slice select tools, like the crop tool, are used in isolating parts of images. The slice tool can be used to divide an image into different sections, and these separate parts can be used as pieces of a web page design once HTML and CSS are applied. The move tool can be used to drag the entirety of a single layer or more if they are selected. Alternatively, once an area of an image is highlighted, the move tool can be used to manually relocate the selected piece to anywhere on the canvas. The marquee is a tool that can make selections that are single row, single column, rectangular and elliptical.
An area that has been selected can be edited without affecting the rest of the image. In contrast to the crop tool, the “marquee” tool allows for more adjustments to the selected area before cropping. The lasso tool is similar to the “marquee” tool, however, the user can make a custom selection by drawing it freehand. The regular “lasso” tool allows the user to have drawing capabilities.
Photoshop will complete the selection once the mouse button is released. The quick selection tool selects areas based on edges, similarly to the magnetic lasso tool. The difference between this tool and the lasso tool is that there is no starting and ending point. For this reason, the selected area can be added onto as much as possible without starting over. By dragging the cursor over the desired area, the quick selection tool detects the edges of the image.
