Add UV-A-radiation-induced fluorescence spectra for seven glass
photography filters.
Add missing metadata to spectra of Rosco gels.
Add spectra for four Cooling (C), four Warming (W) and two
“fluorescent” (FL) colour correction photography filters from Hoya
Tokina.
Rebuild data objects with ‘photobiology’ (0.14.0).
photobiologyFilters 0.6.0
Add function water_n() returning the refractive index
of seawater and freshwater as a function of wavelength and
temperature.
Add data for 197 climate screens, shade nets and other covers used
in horticulture (contributed by T. K. Kotilainen, T. M. Robson and R.
Hernández).
Add spectra for additional photography filters including several
copies of filters of the same type.
Add spectra for UV-pass filter stacks.
Replace some spectra digitized from suppliers’ spectral plot bitmaps
by actual measurements.
Fill-in missing and correct wrong metadata for some photography
filters. This includes the thickness measured for individual
filters.
Rename photography filters to include thickness and size when
available. Code breaking!.
Trim the wavelength range of photography filters to 200 nm to 1020
nm, because outside this range data were heavily affected by instrument
noise. The noise was very noticeable when the data are re-expressed as
absorbance or optical density (O.D.). Code breaking!.
Update refractive index data with freshly downloaded spectra from
the refractive index database. Some materials added and a couple were
removed. The data may be slightly different. Some names changed, e.g.,
acrylic is now PMMA.
Rebuild data objects with ‘photobiology’ (0.11.1).
Compact the spectral data using
photobiology::thin_wl(). Can slightly change the result
of computations and plot details.
Move Git repository from Bitbucket to
GitHub.
photobiologyFilters 0.5.2
Correct wrong thickness metadata in PC and PET_G sheet spectra.
Add thickness metadata for several photography filters.
Add reflectance data for various materials (previously contained in
package ‘photobiologyReflectors’, which was never released through
CRAN).
photobiologyFilters 0.5.1
Add data for Heliopan UVIR-cut “Digital” filter.
Add data for Fotga UV IR CUT filter.
Correct wrong spelling of Tangsinuo Technologies in two filters’
names.
Add filter.properties metadata when available.
Add refractive_index.mspct with data for 15 materials.
Revise the User Guide.
photobiologyFilters 0.5.0
(Code breaking!) Rename many of the member spectra contained in
filters.mspct so that all names start with the brand of the filter.
Rename vectors of names used as accessors to end in
"_filters" to avoid possible conflicts with other
packages.
Add data for various filters used in photography.
Add data for some filters supplied by UQG Optics.
Add data for 49 new filters supplied by MIDOPT.
Add data for 5 old types of UV-pass filters from
Schott.
Rebuild all spectral data objects with current version of package
‘photobiology’ (= 0.9.28), setting “how.measured” attribute when
known.
Remove a non-ASCII character from the data.
Require R 3.5.0 due to the new file format used to store the
data.
photobiologyFilters 0.4.4
Rebuild data objects, setting attribute
"what.measured".
Add data for MIDOPT filters, from Midwest Optical
Systems, Inc.
Add data for different types of window glasses, as used by CIE.
Rename some filters, for clarity and consistency (NOT FULLY
BACKWARDS COMPATIBLE).
Add lists of names by type, colour and by material.
Update documentation, expanding the “User Guide” and removing the
“Data Catalogue”.
Build documentation web site with ‘pkgdown’.
photobiologyFilters 0.4.3
Rebuild data objects.
Update documentation.
Build documentation web site with ‘staticdocs’.
photobiologyFilters 0.4.2
Rebuild data objects. Only change is in dependencies and fixed a bug
in the build.
photobiologyFilters 0.4.1
Update for ‘ggplot2’ 2.0.0, ‘ggspectra’ 0.1.0, and ‘photobiology’
0.9.1.
Only change is in dependencies.
photobiologyFilters 0.4.0
Code breaking update!
Change how data are stored. Data are now in
filter_mspct objects, in most cases each object contains
data for filters from a single supplier.
Replace SCHOTT filter data with those supplied by
SCHOTT. Now data for 67 filters are included and data on
thickness and reflection multiplier are included for each filter
type.
Add data for greenhouse films from XL Horticulture
Ltd.
Simplify and improve all data building scripts.
Revise vignettes to use data in new format and to include new data
added.
photobiologyFilters 0.3.2
Add spectra for some Lee filters (data digitized from data
sheets).
Remove all references to data.table from data object build
scripts.
Rebuild all data objects with ‘photobiology’ (0.8.11).
photobiologyFilters 0.3.1
Rebuid data and package with photobiology 0.8.0 and remove
dependency on package data.table.
photobiologyFilters 0.3.0
Rebuid data and package with photobiology 0.6.0.
photobiologyFilters 0.2.4
Added data for Petri dishes.
photobiologyFilters 0.2.3
Revise script used for creating filter data objects. To avoid
problems with conversions to absorbance and taking into account that
what can be really measured is that transmittance is below the detection
limit of the instrument used, the minimum value of fractional
transmittance has been forced to be 1 E-5, with the meaning of < 1
E-5, consistently with the earlier encoding used for Schott
optical glass filters.
photobiologyFilters 0.2.2
Add data for Plexiglas 2458 GT (SUNTAN).
photobiologyFilters 0.2.1
Rebuild with ‘photobiology’ 0.5.7, which is now required.
The User Guide was updated to use simpler code as allowed
by ‘photobiologygg’ 0.2.5.
photobiologyFilters 0.2.0
Rebuild with ‘photobiology’ 0.5.1, now required, which needed minor
edits to the User Guide.
photobiologyFilters 0.1.13
Rebuild all filter.spct objects with ‘photobiology’ 0.4.6
Vignettes updated.
photobiologyFilters 0.1.12
Added to the ‘catalogue of filters’ vignette plots for filters that
were missing.
photobiologyFilters 0.1.11
Cleaned up the scripts I use for building the data objects. Decided
so save storage space and to only include spectral transmittances
expressed as fractions of one, now that the design of the code in the
‘photobiology’ package is getting stable. Revised the “catalogue of
filters”” vignette to solve some plotting problems, and to simplify the
code used.
photobiologyFilters 0.1.10
Rename all filter spectra objects from .dt to
.spct.
photobiologyFilters 0.1.9
Add data for several plastic sheet types including several types of
Plexiglas.
photobiologyFilters 0.1.8
Add data for many Schott optical filters.
Now data are in data.table format (compatible with data.frame),
added class attributes preparing for future improvements.
Data are now in S3 objects of class "filter.spc" but no
class methods are yet defined.
The names of the variables in the "filter.spc" objects
has changed and now they contain the data both as percentages and
fractions. This makes use easier, but wastes some storage space. Now
‘photobiology’ 0.3.0 or later is required.
photobiologyFilters 0.1.7
Function calc_filter_multipliers() was moved to package
‘photobiology’. However, this should be mostly invisible because the
whole photobiology package is imported.
photobiologyFilters 0.1.6
Add data for some optical glass filters from Schott.
photobiologyFilters 0.1.5
Fix a BAD bug in the rescaling code in
calc_filter_multipliers() that affected the returned values
(percents vs. fractions).
photobiologyFilters 0.1.4
Added missing import directive.
photobiologyFilters 0.1.3
Small edits to vignettes.
photobiologyFilters 0.1.2
Fix documentation.
photobiologyFilters 0.1.1
Add warning to documentation as the spectral transmittance for
Rosco #00 is not that of the filters currently being sold.
photobiologyFilters 0.1.0
First version. Includes transmittance spectra for many of the
filters we have measured during the last 20 years.
