It might surprise you to learn that the transformation from the left image to the right took less than a minute in Photoshop including the loading and saving of the image! Really I hear you ask, how did you manage that? Around three years ago I went along to a Photovision road show and watched in amazement as one of the seminar presenters took image after image and blindly (literally) retouched them in less than a minute at a time. This included in one instance a complete replacement of the sky, including dealing the the sky reflection in a lake. The presenter was called Guy Gowan and he really did open my eyes to a superb way of processing images that doesn’t take a lot of time, but produces superb results 9 times out of 10.
I won’t reveal his secret sauce, although one of the foundations is detailed in a previous post, but I do urge you to go check out his web site (www.guygowan.com) and have your eyes opened to another way of processing that is straightforward, logical and produces great results in no time at all. Obviously in some instances you will want to take the images further and add textures etc to them to bring out the artistic side, but in 90% of your photographs his techniques will nail you the image you were after.
In a previous post I talked about the quest for the twenty in club competitions. Well sometimes you come up with an idea and invest quite a bit of effort working through only for it to just not click. This image is a reject from an attempt at a splash of colour as I desperately tried to avoid falling into the cliche water drop or colour popped picture. It kind of works, but unfortunately my daughters face just doesn’t have the right expression to make it pop for me. Its an interesting picture, but is it a twenty… probably not, and hence it is languishing here.
I did try and gauge it’s popularity by posting it on Facebook and Flickr, but it wasn’t very conclusive. Ah well next image please.
PS. This is the image that was the cause of the controversy.
Photoshop puts a really useful tool at your disposal that can automatically change the levels in an image, but most people seem confused by how it works. They’ve read various books and web sites that suggest that one of the first things you should do when starting to edit an image is to apply automatic levels to it and then in dismay they watch the colours in their image shift all over the place only to be left with a crappy looking image. So whats going on? I hear you ask, why has Photoshop decided to shaft all the colours? Well by default it will auto level each of the RGB channels independently rather than applying the levelling to the luminosity of the image.
You can see this effect in the image below where the left hand side has been auto levelled using the per channel method and the right by the monochromatic method. The image on the left has a colour shift towards green giving the skin a green tint, whereas the one on the right doesn’t, maintaining the natural colours in the image (ignore the fact that it was shot with auto white balance etc). So how do you fix this, don’t despair, it is simple to fix this from the levels dialog.
Open the normal levels dialog by clicking on the menu “Image > Adjustments > Levels…“at which point you should see the dialog below.
Click on the “Options” button and you will now see the “Auto Color Correction Options” the following dialog.
By default this dialog has “Enhance Per Channel Contrast” selected, which as the name suggests performs the auto level operation on each RGB channel independently causing the colour shifts. Select “Enhance Monochromatic Contrast” instead remembering to select the “Save as defaults” checkbox. If you don’t select the checkbox, Photoshop will forget the change! Click on the “OK” button and the “OK” button for the “Levels” dialog.
From now on when you perform an auto levels operation, Photoshop will apply the level operation to the luminosity of the image as a whole and won’t end up colour shifting the image.
