How to Convert DNG to PSD Images and Photos with Python

Image files conversion from one format to another is a common task encountered by every graphic designer. The efficiency and excellence in converting files not only impact the speed of completion but also play a crucial role in assessing the overall work quality. Concerning the images sources, they frequently necessitate transformation into alternative formats more suited for printing or online distribution. An image crafted in a graphic editor is likely to be in vector format. In such instances, for website publication, it must undergo rasterization and be saved in a raster format. You have the option to convert the image in an uncompressed format for superior quality or save it to a lossless compressed format to minimize the file size. For scenarios where file size reduction is obligatory, like in website applications, there’s the possibility of conversion to lossy compression formats. Specialized data compression algorithms for images can significantly diminish file size while upholding acceptable image quality, ensuring swift image loading. To convert images and photos from DNG to PSD, we will employ Aspose.Imaging for Python via .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Python platform. You may install it using the following command from your system command.

The system command line

>> pip install aspose-imaging-python-net

Steps to Convert DNG to PSD via Python

Developers can easily load & convert DNG files to PSD in just a few lines of code.

  • load DNG file with Image.Load method;
  • create & set the instance of required subclass of ImageOptionsBase (e.g. BmpOptions, PngOptions, etc.);
  • call the Image.Save method;
  • pass file path with PSD extension & object of ImageOptionsBase class.

System Requirements

Before running the conversion example code, make sure that you have the following prerequisites:

  • Operating system: Windows or Linux.
  • Development environment: Supports .NET Core 7 and higher, such as Microsoft Visual Studio.

DNG What is DNG File Format

DNG is a digital camera image format used for the storage of raw files. It has been developed by Adobe in September 2004. It was basically developed for digital photography. DNG is an extension of TIFF/EP standard format and uses metadata significantly. In order to manipulate raw data from digital cameras with ease of flexibility and artistic control, photographers opt camera raw files. JPEG and TIFF formats store images that are processed by the camera, therefore not much room for alteration is available in such formats.
