# How to install camera raw

The two most popular use cases for Photoshop are photo retouching and graphics design. With the introduction of Photoshop CS6 Extended, it now supports the entire digital workflow for both professional graphic designers and photographers looking to transform their work into something more visually appealing or professionally styled.

There are a wide variety of tools available in Photoshop. With over 300 tools available, it can be daunting to know where to start when getting started with Photoshop. In this article, we’ll give you a list of the most commonly used tools and tips for working with them.

Preview / Document

The most commonly used tools in the Document/Preview pane are the Rectangle Tool and the Selection Tool.

Let’s start with the Rectangle Tool. To create a rectangular selection, use the Rectangle Tool to create a square on a new layer. Then use the left and right arrow keys to move your selection out to its corners.

To fill a selected area, hold down Alt/Option and use the shape and arrow keys to select the shape you want to fill with the foreground color.

If you want to resize the selected area, use the Shape tool, and use the left or right arrow keys to drag your selection on the canvas. You can also zoom in and out with the Ctrl / Cmd + zoom keys on a Mac.

To edit the size, position, or angle of the shape you select, use the Shape tool with the four arrow keys. Use the up and down arrow keys to move shapes around.

The Selection Tool is the most straightforward tool for creating a selection. Use the Select Tool with Shift / Alt to select objects with a small, quick-moving selection tool. Use the up and down arrow keys to zoom in and out, and the left and right arrow keys to move your selection.

After you have a selection, you can use the Direct Selection Tool to delete selected areas. Or, if you want to paint with your selection, use the Pen Tool to activate the Paint Bucket tool.

Layers

Using layers is one of the most fundamental ways to organize your work. With each layer of your photo you can apply different adjustments and effects to multiple areas.

Layers are available in the Layers window and are represented with icons on the canvas. To add a new layer to your image, simply click in the canvas with the mouse and drag to create a new layer. You can also press the CTRL (Command on a Mac) key and click

But not everyone starts with Photoshop. There are other ways to use Adobe Photoshop to get great results — and here’s how:

Import from Camera Camera

You can use any camera (remember to use manual settings) to capture your images using Photoshop’s Camera Image Import feature. This feature works with RAW images as well as jpgs.

You can perform RAW conversion in Camera Raw before using other editing tools such as the Adjustment Brush, Spot Healing Brush or Smart Brush. Some photographers prefer using Photoshop’s native RAW converter. Your preference will depend on what you find easiest.

The best place to start is to convert a test image that you already have. Use the ‘File > Open’ button and navigate to your test image.

From Camera Raw, you can set your preferences for conversion parameters such as Gamma, Noise Reduction and Sharpening. This is the final edited image.

If your camera supports jpg, it is simple to convert the image from Camera Raw to PSD. A good rule is to always use the Adobe RGB color space for jpg output, which is the default.

Once you have the images in Photoshop, save them to disk and edit as you like.

The Adjustment Brush is another tool to add or remove color from an image and can be used alongside a selection to create a new, edited image. Select the areas you wish to edit by pressing the ‘Backspace’ or ‘Delete’ keys.

Click the Adjustments tab and use the brush to add or subtract contrast, color and brightness from the selected areas. You can mask out areas, such as your face, where you don’t want the effect.

Turn off the Adjustments panel by clicking the small icon in the top right-hand corner of the panel. This makes the brush more precise when you click into your image.

The Selection Brush works in a similar way but doesn’t allow you to edit areas within an image. When the Adjustments panel is off, the Selection Brush is the only tool available.

Image Processing Tools Eraser

If an image is too bright, you can use the Eraser tool to remove areas of light on an image and have shadows reappear on your image.

If you have the Adjustments panel on, use it to change the sharpness, Contour, or Vibrance

other hand, a generalized Gibbs ensemble with long-range correlations would have the following property: the probability of having one large (with size $\propto L$) cluster with $n$ spins flipped can be made arbitrarily small at any temperature. This would in turn imply that the time necessary to re-equilibrate such a system will be of the order of $L^2$. Such a behavior is much faster than the typical behavior $L^4$ found here. This shows that the local character of the correlations observed in our model are strong enough to prevent the complete local equilibration of the system.

In the limit $T\to 0$ the distribution does not change with time. This happens because when $T\to 0$, the strength of the interactions becomes infinite, and by the Mermin-Wagner theorem[@Mera], all fluctuations are suppressed. To make this statement more rigorous, one could analyze the evolution of each single-spin probability density function and show that all single-site probability densities converge towards the same function which does not depend on the lattice geometry. This is straightforward to show, and we leave it for a future publication. This is indeed what is observed in our numerical simulations for the case of the Curie-Weiss model as well as for the variants E and ISA.

For the case of $T\to \infty$, the probability distribution tends to $1/3$ for all the studied variants of the model. The distribution is the closest to $\frac{1}{3}$ when it is the largest (ground state of the Hamiltonian). A simple explanation of this fact comes from the fact that in this limit, all the spin-spin correlations vanish (due to the different ground state energy). Hence, the only relevant factors in the dynamics are the relative concentrations of the four types of interactions (see Eq. (\[H

Q:

Replacing 2D array elements with the values from an empty list

If I have an array of 2D arrays of all of the same length, what is the most efficient way to replace the values of each 2D array by a list? I know I can iterate over the original 2D array, and move through each 2D array element, but I’m wondering if there is a more efficient way in Python.
As an example of what I’m attempting to do, say I have this list:
arr = [[0,0,0,0,0,0],
[0,0,0,0,0,1],
[0,0,0,0,0,1],
[0,0,0,0,0,0],
[0,0,0,0,1,0],
[0,0,1,1,0,0]]

I want to create another list, arr2, such that arr2 = [[1,0,1,0,0,0],
[1,0,1,0,0,0],
[1,0,1,0,0,0],
[1,0,0,0,0,0],
[0,0,0,0,0,0],
