We all could not wait the trip to Samur forest. Wildlife photographer Valery Moseykin, “Photo Expedition” leader and the author and guide of the first eco-tour in Dagestan, was talking about this wonderful forest with admiration since the very beginning. So with expectations that high, the long way from Mahachkala to Samur river actually looked not that long at all. In addition, we saw endless water space of azure and calm Caspian Sea to the left, and Caucasian foothills to the right. Finally we found ourselves at the southernmost point of Russia, almost at the border with Azerbaijan.

Looks surprising, there is an asphalt road through the south-eastern side of the Samur forest. Locals take it to get to Primorsky settlement which is in 350 meters from Azerbaijan. And this road led us right to the heart of the forest.
As soon as we got out of the car, we saw adorable orchids, a species from Orchis genus. Two other species were hiding in the forest next to the glade.

It's morning dawn. Sun starts to climb up. The air is filled with reverberating silence. It is not just the silence, it's like when you hear somebody, from somewhere. In addition, it smells something strange. You do not get used to it overnight sleeping in the tent. Some unusual mix of salt and organics. The landscape, absolutely flat, is seen through for tens of kilometers, if only you are not in any relief depression. These lonely trees which give a subtle shadow – seem to be the only thing that adds a diversity to the landscape. The others are at least in a few kilometers from here. Isn't it an emptyness? True! It's desert. Still, you feel the presence of somebody. Indeed, an amazing feeling.

Viewing photos on iPad: profiles for accurate color


iPad accurate color rendering test: butterflies | macro | landscape

Many photographers use Apple iPad to show their portfolios or photo shoots to clients. The screen of iPad has a great specs including bright back-lit, high resolution, and color display that surpasses lots of laptop dislays. But even the iPad screen has its own peculiar properties which are subject to correct to get the best color display for your photos.

You may get an iPad display profile as described here, by ordering its calibration and profiling, or by downloading the profile here:

Color profile for: iPad | iPad 2 | new iPad


Colors that could be rendered on the iPad screen (black triangle) in comparison to the AdobeRGB color space gamut; the photograph opened in Adobe Photoshop for color conversion.

Assume that you have the right color profile of your iPad. Now you want to convert colors of your image to iPad display profile in Adobe Photoshop. To do that I advise you to rely on Relative Colorimetric intent with black point compensation.
So you should select the menu item Edit > Convert to Profile... that will display the dialog window.


Menu item for color conversion in Adobe Photoshop | Convert to Profile options.

Relative colorimetric intent preserves colors from the source image intact if they can be displayed on the target device (mean iPad), and shifts the colors that are outside of the target device color space. Thanks to that all iPads have an IPS matrix of a high quality, iPad delivers a rich palette of colors. So the quality drop of the converted images should be small.
In the opposite, application of perceptual intent leads to the proportional compression of the source color space to the target one. This could potentially result in surprisingly dimmed colors.

For now you have converted an image to the iPad color profile. It's time to save the file to folder that serves as a source of images to sync. Then synchronize your iPad with iTunes, and it's done.

It's possible to create a simple Action for Adobe Photoshop that will perform with your images all color conversion steps automatically in batch.
There are only three color spaces available in Lightroom: sRGB, ProphotoRGB и AdobeRGB. So, if you would like to export images and convert them to iPad color profile simultaneously, you'll need the print module to select from different color profiles installed in your system and then save your photo(s).

Photos placed above the text as illustrations are adapted for viewing on the original iPad (I cannot afford upgrading my tablet after each release :). So the photos here may look inaccurately on the iPad 2 or the New iPad, and will definitely look wrong on other devices.


Below are pairs of images converted to the iPad color profile and their originals in sRGB. Color distribution of original images is plotted on graphs as well as AdobeRGB (rainbow triangle) and iPad (black triangle) color gamuts.
