Photoshop has ties with other Adobe Software for media editing, animation, and authoring. The .PSD (Photoshop Document), Photoshop's native format, stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. This is in contrast to many other file formats (e.g. .EPS or .GIF) that restrict content to provide streamlined, predictable functionality.
You can't change a PSD file into an INDD file because the INDD format isn't an image format - they're text files. To incorporate the image into the InDesign project, you have to perform a Place (File - Place) to put the image into the ID project. The image file then becomes a part of the overall ID file when it's saved, but it isn't changed to the ID format. InDesign links to the image file for both project presentation and printing purposes.
To import a PSD file into After Effects, go to File Import File, select the PSD file you want to import, and then choose the import options you prefer. After Effects will then import the PSD file, allowing you to work with its layers and assets in your project.
PSD is Photoshop's proprietary format that can store information in multiple layers. It's useful when you have edited/are editing an image in separate layers and want to return at a later time to make changes to one or more of those layers. PSDs also do not use compression, so you won't loose image quality from saving your file; this is ideal for editing and if you want to save out your image in multiple file formats with different resolution and compression settings, while preserving the original image quality within the psd.
Thats format in which image data will be stored. Difference is because some image formats allows you to save editeble layers along with file (PSD) and some don't (JPEG, GIF, PNG).
This PSD file format becomes very popular in recent years.. A web designer can easily change colors to an image , add or remove image layers .. PSDs are really helpful for slicing the images very easily..
I think you mean PSD, which stands for Photo Shop Document. It is the name of the file extension created when you create or edit a multi-layered image in Photoshop.
psd is a photoshop extension and can be opened with photoshop or photoshop elements.
almost any format:.jpg , .gif , .png are most common but you can open almost any other format
Open PSD file in Photoshop then go to File > Save As. In Save As dialog choose from Format drop down list at bottom of dialog: Photoshop EPS.
At present Photoshop does not support CSS when rendering a .psd file to HTML. The only way to use a .psd in web design is to create the image you want displayed (navigation and all) and to then "slice" it in Photoshop. A great tutorial on this is the div tutorial at this site: [http://celestial-star.net] Once you have created the sliced table of images, CSS can then be hard coded to replace the table, this task though would be a challenge for an expert CSS writer. you can also import that PSD file into fireworks and slice in in fireworks and export it as CSS and images
"Photoshop Data file"
PSD is native Photoshop Document.
