Spectrometer: lego, pi NoIR, holographic film grating
Capture: 6 jpgs at various exposure times, combined using the opencv python library to create an HDR using the Debevec algorithm, and compressed to LDR. Artefacts produced by this process (possibly from multiple JPG compression) are visible. A lot of data was lost by compressing the data to LDR in order to display as a .png.
Operations enable reversible modification of data -- they act like filters which process the data. The graph you see above represents the data after these operations have been run. Delete them to undo their effects, or to apply them in a new order.
