In one sentence, describe what the following article is about: Filters, selected from the filter menu and applied to either the visible layer or selection, can be used to achieve a wide variety of effects. When each filter is chosen, a menu with a number of options will be brought up. You can experiment or look online for more details for each filter. For example, you can use the "gaussian blur" to significantly diffuse the pixel on a layer. The "add noise", "clouds", and "texture" filters can give texture to your image. Other filters can be used to give dimension or distort images. You will simply have to experiment to find which is right for your project. Levels allows you control of an image's brightness, color balance and contrast by specifically defining absolute white and absolute black for a given image. This is complex and will require experimentation and practice to execute perfectly. Many tutorials can be found online. Open the levels window by clicking command/control+L. The curves menu allows you to adjust the tones within your image. Bring up this menu by clicking Image -> Adjustments -> Curves. You will see a line going diagonally across a box. The horizontal scale represents the input image and the vertical scale represents the output image. Click on the line to create anchor points and then drag those points to alter the tones in your image. This will give you more control over contrast than the contrast menu will. You can use the transform tools to scale, rotate, skew, stretch, or warp an image. This can be done to a selected area, an entire layer, or a series of layers. Access these tools by clicking Edit -> Transform. This will give you a submenu with a variety of options. Choose which is best for you. Experiment or look up tutorials on the web. Remember to press shift if you wish to keep proportions constrained while using transform tools.
Summary: Use filters. Use levels. Use curves. Use transform tools.

As you would expect, one of the best ways to build a power punch is to practice punching as much as you can. In your punching drills, you'll practice throwing your punches slow and deliberately. Practicing your punches will help you hone your technique and build strength. Position yourself with your feet shoulder-width apart. Make your fists with the thumbs on top of your index fingers. Whatever type of punch you're throwing, practice it on a punching bag or similar aid. Practice punching drills half an hour a day, every other day. Make sure to punch slow. Remember, this is not about quickness, but about power and delivery. Practice a variety of types of punches.

Incorporating a complete cardio/endurance workout into your training regimen will help you in many ways. If you're generally fit, you'll be able to throw a more powerful punch than if you just worked on your upper body. You'll also be able to move around the ring faster, and you'll be less tired as you do so. Incorporate swimming into your overall exercise program. Try to swim 2 or 3 times a week. Swimming will give you a better overall workout than almost all other single exercise activities. Build running into your overall exercise program. Running will improve your cardio condition, increase your endurance, and make you more fit overall. Use a mixed cardio/endurance program. If you don't want to commit to either running or swimming as your single workout, do both, or use other endurance workouts that may be appropriate. Try doing some mixed/balanced weight training using light and heavy weights. Weight training is perhaps the best way to train to deliver a powerful punch. While there are a wide variety of exercises you can do in a weight training routine, consider the following: Light dumbbells (2-5 lbs). Do three sets of curls. Your first set can be 12, your second 10, and your third 8. Adjust sets, reps, and weight as you progress. A timed training routine. Boxing rounds last for about 3 minutes (5 minutes for the UFC) so workout for 3-5 minutes then take a 1 minute break. Try 3 repetitions. While light weight training works well, you may also want to consider heavier weights to build more power. A few good weight training sets for building punching power include: hack squats, dumbbell snatches, deadlifts, box jumps, quarter squats, and squat jumps. Consider 3 sets to starts. While lifting weights helps with the mass for the punching power, it's nearly useless if you want to achieve proper hand speed and coordination. Instead, train with a medicine ball. Training with a medicine ball will work out many of the muscles you'll need to improve your speed, agility, and coordination. Consider the following workout: Hold your medicine ball at shoulder height, standing in front of a wall. Then, lower your knees in a squatting position and explosively throw the ball into the air. Catch the ball (with your hands) and throw it explosively at the wall. Quickly pick up the ball, lift it over your head and then slam it to the ground. Work your way to 5 series of 30 repetitions, then pick a heavier ball. This workout is great because it engages all of your core muscles. Using a jumping rope may look like child's play, but it's not. Using a jumping rope three times a week for fifteen minutes will boost your cardio, increase agility and reaction time, and improve coordination and muscular control.

Problem: Article: This will create a lining between the floor and your guinea pig. This lining will catch any droppings they leave behind while out of their cage. It will also provide a natural boundary for your guinea pig, encouraging them to stay in one place. Once you have returned your guinea pig to their cage, you can remove the lining from the floor. Fold the edges over before rolling it up. This will prevent any debris from falling off the lining onto your floor. If you used newspaper, you can throw it out in the trash can. If you used a fleece blanket, gently brush off debris into a trash can. Wash the blanket before using again. If any poop fell off of the lining, you can scoop it up quickly. Keep a plastic spoon and cup handy right next to the cage. Pick the poop up with the spoon, and drop it into the cup. Dump the cup into the trash can when you are done. Your guinea pig may be able to be trained to only go on newspaper or litter. Every time you see your guinea about to go, move them to the newspaper or a box of litter. Afterward, give them a carrot or other vegetable. Over a few weeks, they may start to only use the litter.
Summary:
Lay down newspaper or a fleece blanket before floor time. Roll up lining after floor time. Scoop poop up with a plastic spoon and cup. Litter train your guinea pig.
