Which Projector Should I Rent?

LCD projectors work better for static Microsoft PowerPoint® presentations or detailed financial spreadsheets. DLP works better for full motion video.

LCD stands for Liquid Crystal Display and DLP stands for Digital Light Processing.

LCD is an analog-based display technology employing three fixed panels of pixels (one panel each for the RED, GREEN, & BLUE components of an NTSC video image). LCD also delivers a somewhat sharper image than DLP at any given resolution.

LCD projectors usually produce significantly higher ANSI lumen outputs than do DLP projectors with the same wattage lamp.DLP projectors have a much higher pixel "fill factor" than LCD. DLP-based projectors generally produce a much smoother looking image compared to LCD-based projectors of similar resolution.

DLP-based projectors have a high contrast ratio and efficient use of light. Contrast ratio compares the ratio between the brightest white and the darkest black that a projector can produce. Generally, a better contrast ratio leads to better black levels and, therefore, a more realistic presentation of darker scenes in movies and TV programs.

DLP projectors tend to be more compact because they have fewer components.

All of the current 3-pound portable projectors on the market are DLP projectors. Most LCD projectors are five pounds and up. The higher lumen models are significantly heavier and larger. High lumen projectors are not considered portable.

You need to match the brightness of the projector to your audience and room size. Large rooms and audiences require high bulb strength brightness. (Projector bulb strength brightness is measured in ANSI lumens or lumens).

All projector rentals range from about 1000 up to 6000+ lumens in brightness. The higher the lumen the brighter the projector.

Up to 1000 lumens -good for low ambient light, presentations.

2000 lumens -These are the most popular units being sold and rented today. Very practical and will work with some ambient light.

3000 lumens -Much Larger unit than the1000 to 2000 lumen units. Good for audiences of less than a hundred with ambient light.

5000 lumens - For audiences of 100 or more under brighter lights

6000+ lumens - For large events like conventions, conferences and tradeshows where thousands of people need to view a presentation at the same time.

Another consideration is portability of the projector. Lower lumen units are the most portable.

As a general rule, as you increase bulb strength brightness, you reduce portability. High lumen projectors are larger and weigh more than low lumen projectors.

Electric Guitar Lessons - Where Should I Begin? (Otherwise You'll Waste Time)

The first thing that most people want to do when they start electric guitar lessons is to learn how to play that songs they hear on the radio or on their favorite CDs.  The problem is that, in my years of playing experience, it can be more frustrating to start off with that goal in mind than to have a more reasonable objective.  Playing the guitar requires technique, practice, and an understanding of how to properly apply pressure to a string to get the sound you want.  Learning how to play your favorite song right away would be frustrating because you lack the basics needed to create the sounds you hear, and it is also the wrong way to go about.

The correct way to go about getting electric guitar lessons is to find someone with experience that offers lessons, and train with that player.  Make sure that your teacher is interested in the same genres of music as you, because a beginner will feel most comfortable with something they are more familiar with.  As you advance in your lessons, it would be a good idea to branch out other genres to try and add some different sounds to your playing.  A good music teacher that is familiar with your favorite genre of music is the best way to start off.

The first thing you will notice about electric guitar lessons from someone who knows how to teach, is that it will start of very basic and very simple.  It is possible that after the first lesson your teacher will have you playing parts of songs, but they will be songs that fit your learning curve and can help you reach your goal of being able to learn your favorite songs.  Once you have the basics of playing the electric guitar, you can then start to experiment on your own and see what kinds of things you can figure out for yourself as opposed to your teacher showing you.

One of the really fun things about electric guitar lessons is hearing your guitar make that chord progression, or that note, that you hear on your favorite albums.  If you are patient and give lessons a chance, then you will find learning on your own to be much easier.  But take the time to lay a strong foundation for your guitar-playing future, and make sure to take some lessons of the basics of playing the electric guitar.
