I recently got a new camera to update my aging (gracefully!)

The first part of this tutorial looked at GIMP desaturate to convert to grayscale, the second part investigated using the Channel Mixer to decompose to grayscale with varying contributions from red, green, and blue, and the third part looked at decomposing

I was fortunate enough on a recent family trip to stay in a vacation home in Kissimmee, FL for a week.

In the first part of this tutorial we had a look at using the Desaturate command to convert images to grayscale.

In the first part of this tutorial we had a look at using the Desaturate command to convert images to grayscale, and how the different options in that command work to produce their results.

This is a long topic, so to keep you from wanting to put your eyes out with a spoon, I’ve tried to break things up a bit.

At the beginning of this month I posted a RAW image of a house that I asked people to process in GIMP to turn it into a black and white image, and to describe their workflows in doing so.

Over in the GIMP users group on Flickr, there has been a recurring challenge where a theme is chosen, and members will post images based around that theme.

Missing Tower!

Relevant XKCD One of my other hobbies besides photography happens to be web programming.

I can’t get enough of playing with this image averaging, it seems.

Back in 2003 Xeni Jardin posting on boingboing highlighted artist Jason Salavon’s work involving averaging together Playboy centerfolds by decade.

An interesting side effect of posting the Getting Around in GIMP tutorials has been meeting new people who are looking for help with images in some way.

Wee Mobile Alabama (Cathedral of the Immaculate Conception) by Pat David I was fooling around again recently with some “Wee Planet” stereographic panoramas (previously mentioned here), and came across some tutorials on doing this with Photoshop/GIMP using…

I’ve got strange habits to fall asleep at night.

In my previous post on Color Curves for Toning/Grading, I looked at the basics of what the Curves dialog lets you do in GIMP.

I was in the process of including my last tutorial on curves in some forum posts around the internet when I visited gimpchat.com again.

Color has this amazing ability to evoke emotional responses from us.

Still there after all these years by Pat David on Flickr.

I recently shot a wedding for a friend and found myself with a few hundred images in RAW format, of which I processed the handful that I liked.

At least I can say that I haven’t done this (yet) when photographing my daughter.

The most patient portrait model in the world… Not too long ago I finally got around to picking up a decent manual flash for exploring lighting and speedlight techniques.

Similar to using dodging and burning is something I like to call “Contour Painting”.

I recently had a party at my house for some co-workers of my wife, and managed to get a few of them to let me shoot some quick photos using my DIY ringflash.

There was a recent thread on the GIMP users forum at Flickr on how to generate luminosity masks (and use them I suppose).

An occasional question comes up concerning the use of Layer Masks for really controlling your edits to an image, and I thought I would approach the basics in this post.

In my previous post on Color Correction, I outlined a method for finding the lightest and darkest values in an image using Colors → Threshold.

Reading some feeds this morning and came across this interesting post at PetaPixel about how The Impossible Project produces instant film still (using an old Polaroid factory & equipment in the Netherlands).

I found an old Polaroid camera among a pile of old stuff in my house recently, and lo and behold it still had film in it!

There seems to be a relatively recent interest in photo post-processing that is centered around recreating the look and feel of vintage photo elements.

The list of all my GIMP tutorials can be found here.

Layers are really key to just about any workflow in GIMP.

I’ve found myself using GIMP more and more lately to manipulate photos, and thought that perhaps some of the things I’ve been playing with might be helpful for other users as well.

Seriously?

I am recently the proud parent of an absolutely amazing little baby girl.

This just keeps getting sadder.

Thanks to the speedtest.net iphone app, I have been monitoring my Comcast Business Class internet speeds and have been mighty upset with the results.

David Zucker remembers Leslie Nielsen in such a wonderful way.

I recently became the new owner of a iPhone 4 after beating my old 3G phone to within inches of its life (not on purpose, just the normal wear and tear sort of life-beating).

I have recently completed the major stages of renovation for a Florida room in my home.

I have been devouring (hehe) Robert Kirkmans The Walking Dead comic for months now, and he has absolutely kept me always rabidly wanting more.

If you’re going to bother photoshopping… You might as well make it interesting!
