Disk Utility User Guide

You can convert the image format and encryption of a disk image.

In the Disk Utility app on your Mac, choose Images Convert, select the disk image file you want to convert, then click Open. Click the Image Format pop-up menu, then choose a new image format. Read-only: The disk image can’t be written to, and is quicker to create and open. Blackmagic RAW background installer in our Autokroma Installer: just tick a checkbox in our install to get Blackmagic RAW Player (double click on.braw to play them) and OS Thumbnails (Windows Explorer, OSX Finder)! Our Windows installer will also warn you if it detected Blackmagic RAW Adobe plugins and offer you the chance to delete them.

For example, if you create a read/write disk image but later want to prevent changes to the image, you can convert it to one of the read-only disk image formats.

In the Disk Utility app on your Mac, choose Images > Convert, select the disk image file you want to convert, then click Open.
Click the Image Format pop-up menu, then choose a new image format.
- Read-only: The disk image can’t be written to, and is quicker to create and open.
- Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.
- Read/write: Allows you to add files to the disk image after it’s created.
- DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
- Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF.
If you want to change the encryption, click the Encryption pop-up menu, then choose an encryption type.
Enter a new name for the image in the Save As field, click Save, then click Done.

The Adobe DNG Converter enables you to easily convert camera-specific raw files from supported cameras to a more universal DNG raw file. Another benefit of using the DNG Converter is backward compatibility.

Note:

Raw Converter For Mac Os High Sierra

Adobe provides backwards compatibility for the latest cameras for use in older versions of Photoshop, Lightroom, Bridge, After Effects, and Photoshop Elements through the DNG Converter.

For conceptual information about raw files and the DNG format, and to understand why you should convert your files to DNG, see the Appendix.

Windows: Adobe DNG Converter

macOS: Adobe DNG Converter

Open the downloaded file and double-click the DNG Converter executable file.
Follow the onscreen instructions.

The DNG Converter is now available in your Programs (Windows) or Applications (macOS) directory. The installation utility is designed to also install a set of color profiles required for the DNG Converter to function properly. These profiles are copied to a common resource location.

Launch the DNG Converter by double-clicking its icon. Alternatively, drag and drop individual images or a folder of images directly onto the Adobe DNG Converter icon. This action automatically launches the converter.
Select the folder of images you'd like to convert to DNG.
Select the location where you want to save the converted DNG files.
Select a naming pattern for the new DNG files:
Document Name: The existing name of the file is used with the DNG extension added.
Add serial numbers or letters to the name: Advanced patterns; an example of the resulting name appears after Name Example.
Specify the following additional settings for the DNG file names:
Begin numbering: Enter the starting serial number if you'd like it to be different from 1.
File Extension: The file extension is automatically set to DNG. You can choose the extension to be either uppercase or lowercase.
If necessary, change the compatibility preferences.
Click Convert. A dialog box showing the status of the conversion appears.

To change compatibility preferences, follow these steps:

In the Preferences section of the DNG Converter dialog box, click Change Preferences.
Choose one of the following options:
Camera Raw 2.4 and later: The DNG file will be readable by Camera Raw 2.4 (Photoshop CS) and later, and Lightroom 1.0 and later
Camera Raw 4.1 and later: The DNG file will be readable by Camera Raw 4.1 (Photoshop CS3) and later, and Lightroom 1.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model.
Camera Raw 4.6 and later: The DNG file will be readable by Camera Raw 4.6 (Photoshop CS3) and later, and Lightroom 2.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model.
Camera Raw 5.4 and later: The DNG file will be readable by Camera Raw 5.4 (Photoshop CS4) and later, and Lightroom 2.4 and later. The DNG file will often be readable by earlier versions, depending on the camera model.
Camera Raw 6.6 and later: The DNG file will be readable by Camera Raw 6.6 (Photoshop CS5) and later, and Lightroom 3.6 and later. The DNG file will often be readable by earlier versions, depending on the camera model.
Camera Raw 7.1 and later: The DNG file will be readable by Camera Raw 7.1 (Photoshop CS6) and later, and Lightroom 4.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model.
Custom:
- Backward Version: DNG 1.1, DNG 1.3, or DNG 1.4 (default 1.4)
- Linear (demosaiced): The image data is stored in an interpolated ('demosaiced') format. This option is useful if a camera's particular mosaic pattern is not supported by a DNG reader. The default mosaic format maximizes the extent of data preserved. Mosaic image data can be converted to linear data, but the reverse is not possible.
- Uncompressed: No compression is applied to the raw image data.

For a video walkthrough of converting your raw files to DNG using the Adobe DNG Converter, see 7:12-9:44 in this video..

A raw file contains the 'raw' data captured by the digital camera sensor before it has been converted to JPEG or TIFF formats. Cameras that create JPEG or TIFF files process (and in the case of JPEG files, compress) the sensor data. When working with raw files, the file is not compressed or processed in the camera. Instead, software gives the user complete control over the conversion settings. For example, white balance is not applied to the raw file but is stored with the file so the software can default to the originally-intended setting. Other information contained in a DNG file includes standard EXIF metadata (just like in JPEG files), date, time, camera used, and camera settings.

Raw files offer the following benefits:

Smaller files than uncompressed TIFF
Does not have the artifacts of compressed JPEGs
Many key camera parameters, such as white balance, can be modified even after the image is captured
You have complete control over conversion settings rather than letting the camera decide
Access to 16-bit data for greater detail and fidelity
Flexibility of converting a single file using multiple conversion settings
