| Description | .psd (Photoshop Document) The .psd format is the native file format of Adobe Photoshop, a widely used graphic editing software. PSD files can store an image with support for most imaging options available in Photoshop. These include layers with masks, transparency, text, alpha channels, and spot colors, among others. This format is commonly used by graphic designers and photographers for detailed image editing, as it allows for extensive manipulation and layering of images. |
| Technical details | The `.psd` (Photoshop Document) format, which is native to Adobe Photoshop, is crucial in the field of graphic design, photo editing, and digital art due to its layered structure. This structure allows for the independent editing of different elements within an image and supports transparency. PSD files can handle various color models (such as RGB, CMYK, and Grayscale) and different bit depths (8, 16, or 32 bits per channel), making them suitable for both digital and print media. Key features include adjustment layers and filters for non-destructive editing, layer styles for adding effects, editable text layers, advanced masking capabilities, and Smart Objects for making scalable edits without losing quality. Additionally, PSD files embed color profiles to ensure consistent color representation across different devices. While PSD files offer a wide range of features, they tend to be large in size due to their lossless RLE compression, making them less optimal for web use compared to formats like JPEG or PNG. Furthermore, PSD files may not be fully compatible with all image editing software, as certain features may not be supported. Despite these limitations, PSD remains a popular choice among professionals due to its versatility. |
