The River Lee rushes by the Beamish and Crawford Brewery on one side, and O’Sullivan Electrical on the other with St. Finbarre’s Cathedral in the background.
I have discovered there’s a dead pixel on my camera’s sensor. Fortunately it doesn’t seem to show itself much but when I take long exposure shots like the one above a little red dot appears in the top-right of the image. It’s easy to get rid of with the clone tool but also annoying.
The Wacom graphics tablet is great fun to play with but I haven’t got it working fully in Linux yet. Ubuntu thinks it’s simply another mouse device and GIMP doesn’t see it as an “extended device”. I spent quite some time on the Ubuntu forums trying to fix it yesterday before giving up and trying it out on a few images.
It’s a little fiddly to begin with, but I think that’s par-for-the-course when using a new tool. I do find that when dodging and burning large sections of images the brush can get stuck and won’t follow the cursor but I’ve read that once it’s properly configured performance is improved so I hope that is fixed then.
Hope you had a nice Christmas Day!
It may be possible to get Photoshop to run in Linux but would you want to? As a research project in the interest of informing the dear readers of this blog I attempted the install.
apt-get install wine. No surprises there. Apt did it’s job and installed everything properly.
How well does it run? After running Wine, up popped the Adobe loading screen and for what seemed like an age it looked for plugins and other assorted stuff. Finally, after a significant wait the Photoshop user interface appeared and I marvelled at how far Wine has gone since I last tried to run Half Life 2. First thing to do was load an image so I clicked File-Open, selected a file and clicked OK. Then, poof! An out of memory error popped up and Photoshop died!
After closing Firefox and Thunderbird I tried again. This time the image loaded but as soon as I tried any operation on it the same error popped up. After briefly searching for an answer and looking through the winerc, I didn’t bother trying a third time. Even if I didn’t have these memory problems I wouldn’t find myself using it. It doesn’t match the rest of the desktop. It’s dog-ugly actually. Windows apps usually are when they’re running in Wine. Bye bye Photoshop! It’s now deleted off my drive.
Linux users – Ubuntu, Debian, Gentoo, Slackware, Red Hat, whatever you use, just use the GIMP. It’s a great piece of software that’s simply different to Photoshop. That doesn’t make it necessarily worse. If you are really hankering after the Photoshop UI then go play with Gimpshop. You’ll feel right at home in no time and you’ll save the 833 Euro that Adobe charges for their cash-cow. Ouch! How can any non-professional afford that?
Oh, Sven is working on colour management for the GIMP to keep all you printing folk happy!
Another alternative, Krita has come a long way since I looked at it last. I installed it this morning using Edgy’s Apt repository and it looks good. From a photographer’s perspective it’s missing a few necessary tools, although a levels tool is in the works. It does have support for CMYK but I’ve never had a use for that and as Cyrille says, all home and business printers use RGB. Some high end printers use CMYK but your local lab will print from Jpeg files so don’t lose sleep over it! I must post a comparision between the GIMP and Krita when I’ve used it before.
You may have seen this already, it’s on delicious, but it’s something I’ll read over later so I want to mention it. This airbrush tutorial is very detailed, showing each step with accompanying screenshots.
The result is quite a stunning image in the Playboy tradition of perfect skin and tones. Fake but it’s what people want!
I posted a similar touch-up tutorial a few months ago, but it concentrated on general techniques for giving a portrait more punch.
PSPI has long been the best way of running Photoshop in the Win32 version of GIMP. I’ve waited for a Linux version with anticipation and it has now been ported! Not all plugins will work, but I tried the trial version of PTLens and once I pointed it at the .dat file it worked perfectly, if quite slowly.
As well as the efforts to run Photoshop actions in GIMP this is a great addition to the GIMP arsenal of plugins and tools to aid photographers!
Need Photoshop plugins? This article reviews 10 free Photoshop plugins. I installed the Virtual Photographer one. It works quite well, although the preview window is a little wonky and don’t move the window or it won’t redraw.
Jakub ‘jimmac’ Steiner has published several demos of the GIMP in action.
Subjects such as defining shortcuts, image templates, transformations and paths and more are covered. Use the mirrors, because I haven’t downloaded the videos myself yet!
A new Noise Ninja release candidate is out now for Linux, Mac and Windows!
I tried the Linux version, and despite having a strange file selector it worked really well! You can try it for yourself, but the unregistered version saves images with a watermark. I’m going to test it on a few more images and may purchase it myslf.
Make sure you download a camera profile for your camera. The 20D one works well!
Here’s yet another photo processing effect that may be destined to become yet another over used style on Flickr: The Sin City Style draws inspiration from the artwork of Frank Miller’s Sin City.
The example image is as gritty and powerful as Miller’s work and hopefully someone won’t write a Photoshop plugin or action to automate it. At least not for a week or so anyway.
GIMP#, a project to provide a “C# wrapper around the GIMP API” and that “enables users to quickly write new GIMP plug-ins using .NET or Mono” has had some exciting developments recently.
Maurits is working on a GIMP# plugin that will hopefully allow GIMP to use Photoshop actions. AFAIK, these are basically files with calls to Photoshop functions. They are self-contained programs using a Photoshop programming API to perform operations on images. There are a countless number of Photoshop actions for download, free, shareware and commercial, so having access to these plugins would give GIMP a huge boost in terms of what it can do.
There are problems, some filters and functions in Photoshop simply aren’t available in GIMP but he has managed to parse 25 filters from the action files.
Lots of actions map on a GIMP equivalent. I downloaded about 100 action files and created a top 25 of most often used functions. At the top are functions like Brightness/Contrast, Set Selection, Gaussian Blur, etc. etc. The first function without a direct GIMP equivalent is the Chrome filter.
In this post I’m going to show you how to go post-process this image:
By the end, we’ll have an image that looks like this:
This tutorial was created using the GIMP, but it’s equally applicable to your favourite editing software as long as it has the same tools. Photoshop, and other editing software should work equally well.
The steps described here are worth practising, and will apply equally well to any portrait!
First of all, I came across this photo on Flickr through my contacts page. Here’s the original photo, and Ayhtnic kindly let me use her image.
After you load the image, the first thing to do is use Auto Levels from the Layer->Colors menu. This tool alone does wonders for most photos, especially if they’ve been captured as Jpeg straight from the camera.
The image is a little noisy so let’s clean it up a bit. Use Selective Gaussian Blur from the Filters->Blur menu. Use small values as we just want to smudge the noise away without losing too much detail. A radius of 3, and delta of 10 worked fairly well here.
Let’s brighten it a bit and add contrast. Use the Curves tool from Layers->Colors for this. The classic “S” shape always adds life to a photo.
Open the Layers dialog and duplicate the background layer.
Select the new layer (called “background copy” here) and use the Curves tool again to brighten this layer a lot.
With the same layer selected (the top one, the “background copy”), we’ll apply some blur. Open up the Gaussian Blur tool, it’s in Filters->Blur. Apply a blur of 5 pixels to the top layer. Don’t worry, we’re not finished!
We’re going to change the “mode” of the top layer now. With the top layer selected, click on the drop down box that says “Normal” and scroll down to “Soft Light”. You can also try other modes, they’ll make for interesting photos!
Notice how the image suddenly changed?
Even with the nice glowing effect, the image looks indistinct. Let’s sharpen the bottom layer. Select that layer in the Layers dialog and load the “Unsharp Mask” filter. This is in Filters->Enhance->Unsharp Mask.
Don’t apply too much sharpening. Make it subtle. The settings in the screenshot work well.
All that’s left is to save the image, save it with a quality setting of 92%. Don’t bother with higher as it’s practically impossible to see any difference in quality.
