LRT is an image
pre-processing software developed by Gunther
Wegner that allows you to prepare time-lapse videos.
an intuitive workflow you can define development parameters, set keyframes
to manage transitions and image colors at large, deflickering them
if needed then save the modified metadata (XMP), and use these new settings
in Adobe image editors like Lightroom, Camera RAW (PS) or After Effects.
The final objective is to feed e.g. Lightroom with images correctly
preprocessed to create a video.
supports JPG and raw formats and is able to manage HDR sequences too.
will find on LRT website several video tutorials that will help you to
create your first time-lapse video within one hour. Here is an
example of such a video.
forum available in English and
German is also at your disposal.
5.x runs on all Windows 32-bit or 64-bit platforms with Java. A license is
available for private or commercial use (with a possible logo).
warmly recommend you to buy the license to encourage Gunther in his
project, all the more if you are fan of time-lapse.

Lightroom, aka LR, is an image library manager and an image processing software.
When we have to manage thousands of pictures saved on disk, we are quickly
lost if we try to manage manually so many data.
manages your image library in sorting your pictures according to various
criteria but more than this it can postprocess them (e.g. rectify the
frame, modify colors, add special effects, etc), create photobooks, slideshows, and even attach
a soundtrack to your video (but LR is not a video editor so you cannot
edit the soundtrack).
the program is really performing is in its capability to load metadata files (XMP) defined e.g. in LRTimelapse,
and to use slideshow templates. This feature allows you to create time-lapse
videos in a few minutes. Here is an example

request you to select 2 of more exposure-compensated images (e.g. one
underexposed at -2 EV and another one overexposed at + 2EV), whether you want
to align source images by matching features, to reduce or not ghosting
artifacts, noise and the chromatic aberration. Based on these settings, it will combine
your images in a few seconds. The image will be displayed in HDR what
could be the limitations of your video card and diplay.
In a last step,
you can fusion exposures or better, apply a tone mapping. This last
processes the resulting image back to 8-bit or 16-bit color space for
display on your screen or to print it. The result is really stunning as we
can show at left, the software showing in a separate windows image
variations from pastel to vivid colors.
Pro also includes basic editing functions of colors (histogram per channel,
saturation, gamma) and luminance (brightness, contrast, smoothing...) completed
with a crop and sharpness functions. At
last, it supports batch processes.
The Tone mapping function is also available as plug-in for Photoshop

defaults typical to that optical combination.
is both a retouching and a corrective tool, although this second feature
is the most developed.
DxO comes with an impressive serie of functions to rectify most optical aberrations from those typical to fisheye or
wide-angle lenses, to distorsion, vignetting, chromatism, high-lights
reducer, and other light-related defaults.
very useful function is the parallel; instead of rotating a plan to level
it at some occasions it is preferable to distort the image. DxO allows to
manually adjust lens distortion by tracing two
separate lines in the image.
tools applying the latest technologies, DxO provides a HDR-like tool and manages High ISO in reducing
the electronic noise. It includes a technology à la "U Point"
named multipoint color balance (MPCB) to change colors and luminosity of a
more or less extended and fuzzy area, it includes a dust removal tool, a curve editing,
and is also able to add artistic effects.

(in 32 bit mode).
NX combines powerful RAW image processing software and a file management. The
RAW editing features are Nikon NEF specific, but there are a number of other
editing controls for JPEG and TIFF files.
Capture NX 2 looks similar to the
previous version, but there are useful changes : you can configure and
save custom workspaces, have a dual monitor support with the additional
space for your image on one display and the various palettes on the other.
It also integrates a browser to find images as well as apply ratings and
labels. It adds a Favorites panel to the folders tab to help with
accessing the files you work with most frequently. The Metadata tab is
available to assign more info if you wish, including keywords, copyright
notice, and contact information.
improvements are also obvious with the program keeping up with most
editing tasks. Batch processing is welcome but a bit slow, even running on
the most recent and faster computers (the processing of hundreds of images
can last several days).
processing tools, in addition to the Color Control Point method of
selection in the previous version, there are Select Control Points using
U Point technology. When selected, you can drag out a slider to set the
radius that will be affected by the selection. You can also set the
opacity of the selection, and whether to view a combination of the
selection and the original image, or just a mask view that is very useful
to verify what you've selected. For more localized control, the Selection
Brush lets you paint your selection, after which you have all of the same
adjustment options. There is also an Auto Retouch Brush (bandaid icon)
that works extremely well with a variety of clean-up tasks. This tool is
similar to the Healing tool in Photoshop but works easier and faster.
NEF files, there are Picture Control settings and utility to create your
own control settings, including non-destructive editing capabilities. The
new version includes Highlight and Shadow Protection, controls that help to
recover details in either the shadow or highlight range (like do Lightroom
or Camera Raw). Used with a NEF file, the Highlight Protection control can
recover even more information than possible with a TIFF or JPG file.
NX 2 includes filters, a full set of effects
(similar to the ones available in Photoshop) and supports plug-ins like
Color Efex from Nik Software. Note that all adjustments
and filters are listed in the Edit List (like the Photoshop History) that
you can change or disable or delete at will.

its name suggests, it is an automatic image stitching, in other words an
application able to create a panorama from individual images.
by Matthew Brown from the University of British Columbia, Autostitch does
not require any tutorial. At first run, check the Edit, Options menu, in
particular the output file size (e.g. 4000x1500 pixels), the JPEG quality
(e.g. 100%), and the possible matching options (pixel min. dimension,
scale, number of iterations, etc).
select at least two images to assemble via File, Open and the stitching
will start. The algorithm will align selected images and improve its
rendering to display a final image free of joins and other artifacts.
Depending on the image resolution the assembly and rendering lasts between
a few seconds and some minutes. The result is really stunning as you can
see at left on this panorama of Barcelona that I took.
at version 2.2, Autostitch runs on all Windows 32 or 64-bit
platforms. It is free for non-commercial use.

is for short how improved Photoshop along the years.
Version 1 was released in February 1990 for
MacOS. It supported Colormatch colors from Pantone.
November 1992, Photoshop version 2.5
was adapted to Windows.
Version 3 (Sept 1994 for Apple and
Nov 1994 for Windows) added tab palettes.
Version 4 (Nov 1996) added adjustable
layers and editable type rather than rasterized.
Version 5 (May
1998) added Color management and a reduced color space named sRGB. This
color space didn't please users and version 5.5 (Feb 1999) added the
Adobe RGB (1998) gamut aka SMTPE-240M, a TV standard much more extended.
This version also included the Extract feature.
Version 6 (Sep 2000)
added the "liquify" filter and color management (support for ICC profiles).
Version 7 (April 2002) added full vectorial text and healing brush.
8 (Oct 2003) aka "CS" standing for 'Creative Suites", code name "Dark Matter", added a "lens
blur" filter, real-time histogram, commands like shadow/highlight
and match colour, and last but not least the Hight-Dynamic Range, HDR.
then, all "CS" versions integrate a complete suite of products to create and edit images or for
designing and authoring a web site.
Version CS2 aka PS 9 was released in 2005. Among other things it supported tens of
plug-ins to name
Camera Raw (released in 2003) to process raw pictures from
compact cameras and DSLR (4th image from top), "Viveza" from Nik
Software that takes advantage of "U-Point" technology,
"Universe Image Creator" from Diard
Software and more recently (2007) "Tone mapping" from HDRSoft,
among many others tools.
that time, in addition to foreign language support (French, etc),
Photoshop is available in two versions : Standard or Extended.
Extended version includes all features of the Standard version plus new
tools to create and edit 3D imagery and 3D composite objects, including
extrusions, rotation, inflate, bevel, as well as image analysis and motion. The Extended version is thus more
oriented to 3D imaging, film and video graphic and web design.
aka PS 10 was released in 2007. It includes new creative content (shapes, styles,
swatches, etc), new industry-leading color correction, an auto-alignment
of layers and an auto-blending of images.
CS4 aka PS 11 was released in 2009 and provides a new content-aware scaling tool, a
smoother zoom and pan, a extended depth of field and support 64-bit OS,
Multitouch (with an Internet connection) and custom panels.
Version CS5 aka PS 12
was released in 2010. It includes a "content-aware" functionality;
even if it is perfectible, its allows to remove an object from the
image and to reconstruct the background in only one mouse-clic. It aslo
includes a new Puppet warp.
In the Extended
version, the 3D functions have also been improved.
CS6 was released in 2012 and includes 23 new features, including a
new interface, darker, a content-aware patch and move, a new crop tool, a
skin tone-aware selections and masking, improved auto-corrections, a blur
gallery, an adaptive wide angle for lens correction and new type styles (more like
InDesign) among other
2012, a Creative
Cloud version, aka "CC" version is available. It requires an
Internet connexion for the subscription and the first local installation.
Then you can use it locally.
versions also support 3D printing. Note that for photographers, the CC
version includes a Shake Reduction feature that, under the right
conditions, can reduce or eliminate the image blurring due to a vibration
or a shook during the exposure.
CC, instead of buying a licence, the user pays a monthly fee (about 24€/month per application or

is not difficult to use but with all its options it is a complex
application that requires practice and time to be mastered. So, due to its many
tools, it is by far preferable to get training by a professional than
trying to learn as a self-taugh person Photoshop by trial and errors.
books, DVDs and video tutorials, including made by Adobe, are dedicated to this bestseller. Any large
bookshop has also a shelf dedicated to Photoshop.

my humble opinion this is the big brother of Buil's QMiPS2. Its tools
are powerful and numerous, to list a few : blinking and animation over 40
frames per second, pseudocolor palette, linear to gamma power transfer
functions, astrometric calibration, aperture photometry, data analysis
including histogram of pixels and radial brightness profile, histogram
plots, artifact repair... A few among hundreds of commands accessible
in a few keystrokes.
arithmetic and electronic frames operations are provided as special as
blend image, change sign, square root, subtraction of the dark frame or
bias signature. Geometric transformation have not been forgotten as
high-pass filters. Optionally a Maximum Entropy module with or without PSF can be added to deconvolve images and increase
their spatial resolution.
the other side, low-pass filters can be used to remove isolated bad pixels
or smoothing both in weight and height. You can even create your own
filter kernels or special filters as Rotational Gradient suited to reveal
details in radial structure objects such as comets, block average and sum for software
provides plug-ins interfaces to open alien files formats, math plugs-ins
to process images and make measurements and a script language with batch

also create your own plug-ins writting Visual C++ routines.
last it is able to acquire SBIG, Celestron Pixcel and Lynxx CCD images through its
ACCI module which incorporates a tag to help you to find the best focus
using the radial profile method. It read and saves in FITS, TIFF, JPEG and BMP
formats of any size, from 8 to 64 bit, including 24-bit color and can read ASCII
text and binary files.
also exists in version Pro (more features) and AL (for students).
at version 7, MIRA AP runs on all MacOS X, Windows 32-bit and 64-bit, and
Linux platforms. A must for its remarkable performances.
