Today most monitors can display 24-bit color. And with 24-bit color you can display 16,777,216 colors. That is a pretty impressive number and so you might wonder why would you need more? I'll show you that there are situations where 30-bit color can make a huge difference.

Cheap monitors
Many today's LCDs aren't suitable not even for photography viewing, because they have panels with 6 bits per RGB color only (giving 18 bits in total). On such monitors you will see a serious banding even on ordinary 8-bit (24-bit) images. I have prepared two images for you, the first one is with 8-bit gray gradient and the second one with 6-bit gray gradient. You should be seeing a serious banding on the second image. If both images look similar then you have a cheap 6-bit panel and if you're into photography, get rid of it.

Wide gamut monitors
In last years many wide gamut LCDs have been introduced. At the first glance this might look as an improvement with no drawbacks. But it has one - the wider the gamut, the less bits for ordinary sRGB images. Therefore you might experience a slightly more banding then with your old 24-bit sRGB monitor. And this is one of the reasons when 30-bit displays make sense - when you have a device capable of displaying a wider color gamut.

Grayscale images
Many photographers prefer black and white photography over color. But when you start working with grayscale images you might be surprised by more severe banding than with color images. Why is that? Because all RGB channels contain same data, suddenly 24-bit color happens to be 8-bit color, giving you 256 levels only! With 30-bit capable hardware and software you'll be able to see such images with 10-bit resolution, giving you 1024 levels.

What do I need?

• Zoner Photo Studio 12 Professional (make sure that you have Build 9 or higher)
• 30-bit capable graphic card with OpenGL drivers (NVIDIA Quadro FX or ATI FirePro)
• 30-bit capable display (NEC or EIZO LCD, search for 10-bit or 30-bit color support)
• 16/48-bit image (RAW images can be used as a source of such data)

How do I turn it on?

If you have a 30-bit capable hardware, you'll have a checkbox enabled on the Advanced page in Zoner Photo Studio's Preferences dialog. Tick it on.

• 30-bit display support is available in the Editor only (RAW module will support this in ZPS13)
• In Windows Vista and Windows 7 this feature turns off Aero
• When other window appears over the 30-bit window, image will be drawn in 24-bit depth
• Tested on NVIDIA cards only, please let me know if you have ATI based 30-bit capable configuration

Version 12 brings a few significant changes to the user interface. In previous versions the interface was highly configurable and this brought confusion to many users. These new changes introduce some limitations and bring also new possibilities. Let’s take a closer look.

Modules

Zoner Photo Studio consists of four different modules: Manager, Viewer, Editor and RAW. You can switch between these modules using buttons on the top right, every new window is opened in a new tab. Manager and Viewer can be of one instance only. If you need more Browser windows, you can open a second one from Workspace menu in the Manager. Also note that Manager module can’t be closed once it is opened.

Tabs

Zoner wanted to offer to users a more familiar style of window organization and decided for tabs. This change has impact on many functions. First, multi-monitor support is now much more limited, only a slideshow window can be opened on a different screen. Switching between fullscreen and windowed mode has also changed – there are three fullscreen modes now and you can turn them on/off using F11, Ctrl+F11 and F12 keys. In these modes hidden tabs and toolbars will be shown when you move mouse cursor to the top of the window. Regarding the control of tabs, you can switch between them using left mouse button and close a tab using middle mouse button. You can also control tabs from a keyboard – you can switch between them using Ctrl+Tab, close the current one using Ctrl+F4 or Esc.

RAW module

RAW conversion dialog from the last version is replaced by a new RAW conversion module. With this module it is possible to control much more parameters, it is possible to copy settings among pictures and the RAW module also lets you put pictures into a processing queue.

Theme

As you have probably noticed, ZPS12 has a dark user interface. You can choose from four gray themes or use a system based theme.

One of the most important and challenging tasks in digital photography is image sharpening. Although many methods like Unsharp mask provide good results and became a standard, we're still searching for a better sharpening method. Zoner Photo Studio 12 introduces a new method for image sharpening which is featured as a Soft Contours effect.

The difference among the newly introduced method and other conventional methods is that you can control sharpness of details of a different size independently and that you can not only enhance them, but also suppress them. This is especially important and powerful when sharpening portraits, because you can sharpen the most important smallest details of eyes or eyebrows and hide skin blemishes and soften the look of the portrait at once. Let's see an example...

The effect is controlled by four sliders, where every slider controls a presence of details of a specific size. When value is equal to one then there's no change. When you push slider to higher values then you'll emphasize the desired details, when you push it to the left, you'll suppress or completely remove them. Another three images in the gallery above show which details are affected by which slider, going from the smallest details to bigger.

Of course this new method can be used in other situations too. I've prepared another example to demonstrate the effect...
