This article will offer an intro to Photoshop as well as a step by step guide on how to use a specific Photoshop feature called clipping masks. I’ll then give a step by step guide to using Photoshop for image retouching.
Key Photoshop Features
When you start to use Photoshop, you will quickly come to appreciate the multitude of features available. In the same way there are many different styles of painting, many different styles of film making, and even different styles of music, there are many different styles of image manipulation. Photoshop has many features that enable you to edit and manipulate images in various ways. In this section, I’ll introduce you to some of the key aspects of using Photoshop.
Layer-Based Editing System
In this system, you use layers for your edits. As you open an image, you see a background. On top of this background are things like layers for your image, your outline, your colors, and so on. You can use these layers to edit the image as you wish. You can move, resize, change the color, and so on. The more you use Photoshop, the more you will notice how robust this system is.
The background layer is the unaltered photo you started with, the one you will have as the starting point for all your edits. It’s important to note that it’s in the background layer that you will usually see the layers for colors, curves, black and white, etc. You can use the Eraser tool to erase parts of the background layer.
Next is the Canvas layer. It’s a white layer. As you paint on the Canvas, the image will appear underneath. The Canvas is a key tool in Photoshop because it allows you to create your image. It’s also good for measuring as you are creating your image. The canvas has a boundary around the image so it can be seen and edited.
When you paint with the Canvas layer, the parts that you paint are visible. However, they are not completely visible. You can use the Layer Mask tool to mask the areas you don’t want to paint. By default, the Layer Mask tool will be on the bottom layer. However, you can use the Layer Mask tool to mask off the Canvas layer as well.
Components of Photoshop
Another key feature of Photoshop is the collection of tools and tools that can be used to create your image. In the
You can download Photoshop Elements from Adobe.
Using the program
You download the installation file and follow the instructions that come with it. If you are using a Mac, click the Download Now button, and on Windows, click the Download Adobe Photoshop Elements link.
The free software is installed. You are allowed to use the program forever; there is no need to subscribe to any monthly plan. You also do not need an Adobe ID to use it. You can use any kind of login credentials. If you get tired of the program, you can easily remove it from your PC, without losing any information. It is a suitable solution for users who are not sure about the long term use of paid products.
The first thing you need to do when you open Photoshop Elements for the first time is create an account if you are not using one already. You are going to create an account in a moment, but in the meantime, you can try out the program as a free editor. If you are not a member of Adobe Creative Cloud, your account will be treated as a trial account that expires in seven days. You are allowed to use the program for six months with this trial feature.
The interface is not hard to use, but the steps to do what you want with the software are different from the regular Photoshop.
Do you want to edit a picture? Click on Picture > Edit > Enhance, and select the crop feature on the left side of the window.
Do you want to remove a blemish or crop the picture? Click on Filter > Enhance > Crop.
You can also click on Filter > Adjust > Reduce Noise. This will remove all the unwanted noise and sharpness, while preserving the details.
Closing the window (Windows) or closing (Mac) the program will turn off the On switch on the PC or turn the “Close” button on the Mac. If you want to exit without saving your changes, click on the slider of the final row on the left to turn it off.
Click on File > Save, or press Ctrl+S on the PC to open the saving dialog. Specify the file name, the destination folder and the quality.
How to make new images with Photoshop Elements
You can also open and save new images or edit existing ones. In the main window, click on Image > New, then choose the option that is best for you, and follow the steps that appear.
Casting an Object directly to a String
Is there any way to simply cast an object in java directly to a string instead of going through the toString() method?
There are two ways to do it:
String s = (String) obj;
String s = Objects.toString(obj);
If the object is a String or a wrapper around String then that’s the more convenient way, but if it’s anything else, use the second line. The above could easily be optimized to do:
String s = Objects.toString(obj);
if (obj instanceof String)
s = (String) obj;
In any case, if you want to use “simplicity”, use the first line.
Sure, this’ll do:
String s = obj.toString();
But I’d question the need.
Both @Logan and @Sotirios already covered the correct answer, so feel free to up-vote those answers instead.
But if you want something different, I have a quick idea.
I wrote something similar once, and it does this:
String s = null;
if (((String)obj).length() > 0)
s = (String)obj;
I haven’t tested it, but it seems to work, and I think it may handle some corner cases better than other answers.

Non-linear dynamics of a biofilm-forming test microorganism, Pseudomonas putida F1 on silica-alumina surfaces.
The development of a biofilm by the bacterial surrogate Pseudomonas putida F1 (PTN 8339), on the surface of silica-alumina materials, is modeled using a combination of theoretical and empirical methods. The theoretical model takes into account the stochasticity of bacterial cell division and accounts for the diffusion of soluble antibiotics that inhibits cell growth. In addition, experimental results obtained from growth curves, spatial measurements and fluorescence microscopy were used to refine the model. The model was able to predict the biofilm sizes, the amount of biofilm biomass and the distribution of cells within the biofilm as a function of varying inoculum densities. The model with parameters optimized for this system suggested that the thickness of the biofilm and the underlying surface concentration of solutes play an important role in the growth rate of a P. putida F1 biofilm./*
