class RawImageFileReader2(config={}, **kwds)

Bases: Component

Read ‘raw’ still image file (CR2, NEF, etc.).

This component uses the rawpy Python package. See RawImageFileReader for a component that uses rawkit.

Note that the file is always read in 16-bit linear mode. You will need to convert the image to “gamma corrected” mode before displaying it or saving it to JPEG or similar. See gammacorrection for some useful components.

Some options add significantly to the processing time, particularly fbdd_noise_reduction and some of the demosaic_algorithm options.

Config
path	str	Path name of file to be read.
demosaic_algorithm	str	Set demosaicing method. Possible values: 'LINEAR', 'VNG', 'PPG', 'AHD', 'DCB', 'DHT', 'AAHD'.
four_color_rgb	bool	Use separate interpolation for 2 green channels.
dcb_iterations	int	Number of passes of DCB interpolation.
dcb_enhance	bool	Enhance colours of DCB interpolation.
fbdd_noise_reduction	str	Enable FBDD noise reduction before demosaicing. Possible values: 'Off', 'Light', 'Full'.
noise_thr	float	Set denoising threshold. Typically 100 to 1000.
median_filter_passes	int	Number of median filter passes after demosaicing.
use_camera_wb	bool	Use camera defined white balance.
use_auto_wb	bool	Automatic white balance.
user_wb	str	4 comma separated floats that set the gain of each channel.
output_color	str	Set colour space. Possible values: 'raw', 'sRGB', 'Adobe', 'Wide', 'ProPhoto', 'XYZ', 'ACES', 'P3D65', 'Rec2020'.
bright	float	Brightness / white level scaling.
highlight_mode	str	Set highlight mode. Possible values: 'Clip', 'Ignore', 'Blend', 'ReconstructDefault', '3', '4', '6', '7', '8', '9'.
exp_shift	float	Exposure shift. Darken if < 1.0, lighten if > 1.0.
red_scale	float	Chromatic aberration correction red scale factor.
blue_scale	float	Chromatic aberration correction blue scale factor.
crop	bool	Auto crop image to dimensions in metadata.
