If you want to just select an area click on the marquee tool in the toolbar. Once selected, you'll see a drop down at the top called Style with the default set to Normal. Select Fixed Size from the option and enter the values into the right boxes. Notice, with this option, dragging the mouse is no longer necessary as the box is a fixed size. You just need to ...

A well know technique is called "luminosity masks". You create a selection mask where the pixels selection level is: 100% or near 100% in the luminosity range that you want to change, 0% or very low in the luminosity range you don't want to change, intermediate for pixels between these two ranges This done by: making a grayscale copy of your image ...

Simply select and copy the screen/glare you want to overlay, and paste it to a new layer. Set the Blending Mode to Hard Light. Then paste in your product image in a new layer and place it underneath the glare layer (you will obviously need to do some jiggery pokery to fit this image onto the screen in the photo). Result:

I'd guess it's as simple as selecting the subject in Photoshop - with a tad more care & attention than I've used below, then leeching out the saturation in the background & tonally balancing towards a sepia effect. As a very quick demo I did the same thing but made it a pretty garish purple instead. Once you have your mask you can treat inside &...

you can download and use the Adobe Creative Suite Cleaner Tool to clear the errors in the uninstall.. Download from the following link and try that: http://www.adobe.com/support/contact/cscleanertool.html Download and "Run as Administrator" and then restart your machine.

I think the main problem is one of dynamic range, your algorithm is probably right but you're working on the wrong type of data. A point light source that would otherwise clip and go pure white gets spread over a larger area by a defocussed lens, so that it forms a disc that isn't as bright and therefore doesn't clip. That's why you get those nice circles ...

Lightroom always uses a catalog to store your edits, however you can disable the backup notifications. Go to: Edit->Catalog Settings (PC) OR Lightroom->Catalog Settings (Mac) Set: "Back up catalog" to "Never"

Short Answer No, decoding is not guaranteed to always be the same. However, the differences are guaranteed to be very, very small. ISO Specifications The International Organization for Standardization (ISO) specifications for JPEG has the following specifications for decoders (emphasis mine): A decoder shall a) with appropriate accuracy, convert ...

Darktable handles JPEGs almost as RAWs. It just activates different processing modules by default, and e.g. the demosaicing module is of no effect for obvious reasons. See the Darktables module dependencies diagram. This diagramm is loosely processed from the bottom to the top by darktable. So, the arrows are followed in reverse direction. The user can ...

You answer lies in Lightroom and this free software plugin for lightroom http://lrtimelapse.com/ NOTE: this will only work for free for short timelapse segments. Anything over 400 images requires a license. The great thing about using lightroom for a timelapse is that you can easily crop,edit thousands of images with a simple click. You can then make a ...

Canon So far what we know based on ML work DRYOS version 2.3, release #0023 5Dm2 500d/T1i 50D DRYOS version 2.3, release #0039 7D 1Dm4 DRYOS version 2.3, release #0043 550d/T2i DRYOS version 2.3, release #0044 or #0049 5dm3 EOS M DRYOS version 2.3, release #0047 60D 600D/T3i 1100D/T3 I'm generalizing but I see in Canon P&S they tend to ...

If you are talking about JPEG files, then the utility jpeginfo is exactly what you're looking for. It can check files for different types of JPEG errors and corruption and either return an error code (the most useful thing for scripting), or just delete files with errors. I use this as part of my initial file transfer, to make sure everything copied okay ...

Yes they can, but there are some significant caveats. Although they can be run alone, the plugins were not designed to be used as a standalone application. If you have the folder with the executable file (NOT the plugin file) for a specific Nik suite plugin open on your desktop and drag a jpeg or tiff file and drop it onto the executable file (NOT into a ...

This particular logo is easy, because: It's only three colors It's relatively simple vector art there's a simple outline around the shapes The goal is reconstruction, not preservation of a masterpiece That means you don't need to light it very well and you don't need to worry too much about noise. Take a photograph straight down, and notice any sources of ...

The image I uploaded was rejected because it was under 300 DPI. The DPI is just a number which has no relevance to a digital image. It relates only to printing and not the quality or resolution of the image itself. If you change the number to 300 DPI in an editor, it should be accepted. As you have Windows 10 and presumably use assistive technology to e....

Have a look at snapshots, top left in the darkroom mode. For details, have a look at https://www.darktable.org/usermanual/en/snapshots.html

I think you'll be fine. Look at the case of Aperture, discontinued by Apple. Adobe offers an Aperture import plug-in. Lightroom's catalog is an SQLite database and much of the data stored within it is in XML format so the data is very accessible to programmers if the need arises. In the unlikely event that Adobe and Lightroom ceased to exist, it would easy ...

If you are looking for something closer in spirit to Aperture or Lightroom, consider Darktable. Open source, all that. http://www.darktable.org/ Its not as polished as Aperture or Lightroom, but it works, and is free. It has an active development group, and it gets better all the time.

Photoshop's Batch command can do this. You would essentially 'record' yourself performing the crop etc once, then run the recording on all the files you want. If you want to automatically resize the smaller images you would have to do a little scripting. Irfanview also has a comprehensive image batch processor but might require a bit of experimentation to ...

First of all, in optics, only light adds up and darkness does not. Make sure that your algorithm does not bleed dark pixels outwards their original location. Resulting pixels should rather resemble maximum of nearby source pixels than average. Or, to be even more exact, you'd be summing up logarithms of affecting source pixels. Another possible cause why ...

The display corruption could be a consequence of using GPU acceleration in the ACR module. Not all cards are supported, so try toggling off the option. Also make sure that option is off in Photoshop.

ImageMagick let's you run commands in a windows command window. You need to be comfortable with creating Dos batch files. For an example see the last post in this discussion: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=21112 Relevant example from this forum post: @echo off cd C:\Users\user\Desktop\New\New folder convert *.jpg -...

This is a non technical answer. I just want to describe my experiences using both. Darktable I use Darktable (version 1.2) on Ubuntu 12.10 and on OSX and the RAW handling is pretty slow, but it handles JPEG processing swiftly and with no processing time. It can get flustered and will often bomb out if you do massive imports of JPEGs. I shoot JPEG for ...

Yes, because it is only claiming to be better than what they had before. RAW files are camera specific and they introduced camera specific profiles for 70 cameras. It does not appear they are claiming that they now have the best RAW processing around, but only that it is improved over where their ability to deal with RAW files was before. RAW files ...

This processing is implemented in darktable via the Local contrast module as explained here. The interface probably isn't as sophisticated as you might like, but may be an improvement on software that errs on the side of user-friendliness. To quote the linked mail: this module enhances local contrast by using ``Unnormalized bilateral filtering'' as ...

I'll interpret your question in the opposite way everyone else has. You seem to me to be asking how to prevent the details becoming visible again. Once you have darkened your image, increase the black point. This will make the new shadows actually black, and prevent the details from being recovered. You can do this in levels in most editors, or with curves: ...

Assuming that: The focal length has been recorded in the file metadata You are running a Unix-like OS such as Linux or OS X (or Cygwin in Windows) You have installed the exif command line tool Run this on the command line: exif /path/to/your/photos/* | grep "Focal Length [^A-Za-z]*|" \ | awk -F "|" '{print $2}' | awk '{print $1}' | sort | uniq -c | sort ...

First we rename all *.JPG files based on their creation date. Sometimes cameras change the file name or just ordering them is somehow not what we want. However, renaming them by the creation date always work: jhead -n%Y%m%d-%H%M%S *.JPG After that we put this list in a file: ls -1tr | grep -v files.txt > files.txt And then use mencoder to create an ...
