There are so many models of digital cameras available in todays market, that it becomes a rather difficult task to pick the best buy among so many options. Perhaps a few steps should be taken into consideration when choosing the right camera. Will the camera be for daily use, or just for special occasions like birthdays, family reunions, etc. Will the price of the camera make much difference on the pocket?

Assuming that price is not an issue, one should choose a well known major brand camera and if possible, go for the latest model and with the highest number of mega pixels available. The higher the mega pixels, the better the picture will be specially if there is an intention of having photo enlargements quite often. A good quality optical zoom lens will also make a big difference. Choose a camera which comes with a battery that holds a good charge, this way you can enjoy lots of picture taking without having to be worried when the battery charge will come down.

The range of features available make a digital camera very cost effective and more than likely you will be able to find the right camera suited to satisfy your needs.

If you enjoy printing enlargements of your photographs, you may want to pay close attention to the printing size and what is required in mega pixels for you to have good quality results. For you to have an idea of the amount of mega pixels required for most commonly used size of prints, refer to the chart below:

For photos 2x6 inches - 2 mega pixels
For photos 5x7 inches - 3 mega pixels
For photos 8x10 inches -7 mega pixels
For photos 11x14 inches - 14 mega pixels
For photos 16x28 inches - 28 mega pixels
For photos 20x30 inches - 54 megapixels

The handling and design also matters and the lightweight ones are much nicer to carry around. Choose a camera that is user-friendly and make sure that you have a good local technical assistance in case you may run into problems with it.

There are several advantages of having a digital camera instead of the old traditional film camera. First of all, there are no films to be purchased ever. You make take dozens, perhaps hundreds of photos and instantly delete the ones you dont like, or that did not came well into focus and just keep the best ones. You may load them into your computer album, record them and you may view your favorite photos from you camera or from your television set. Some digital cameras also come with a recording device that allows you to record special events and replay them immediately after recording

Digital cameras take pictures that are stored in digital media. It is possible to select, save or delete photos without any cost whatsoever. The photos are usually stored in media cards into the hundreds, meaning that you can take as many pictures as you like before you run out of space. Also in most digital cameras, the user can view the pictures on the LCD screen, which will allow him to pick the best ones.

No wonder that digital cameras became so popular and accessible item to almost everyone. It became a must to have one nowadays and even cell phone cameras are getting better everyday with noticeable improvements in quality of picture taken. The earlier models of cell phone cameras were somewhat limited as far as picture quality is concerned comparing to the ones we find on todays market. The mega pixels are increasing constantly and so the quality of the cameras. If a person needs to carry both at the same time, maybe a cell phone with a digital camera built in will be an interesting option to consider

If you have not bought yet a digital camera, maybe this the right time to do so, considering the manufactures are offering so many new models with new features at bargain prices. It is wise to compare the several models among different manufacturers and also the prices from traditional and online stores. Make sure you do your research right, and most likely you will find the digital camera you are looking for.

The first message that she was dying came by bicycle. Sean Patrick rode up the steep trail on Smuggler Mountain, Aspen, Colorado, on a cool, pre-fall day in 1995. She had spent many summer afternoons biking through the Aspen groves, enjoying the late sun shining patchwork on the trail. Normally energized from the strenuous workout and her daily 15- to 22-mile rides, Patrick was shocked when she became so out of breath that she had to get off the bike to avoid throwing up.

It was radical, she says. I couldnt get up. At first she thought she had over trained or suffered from exhaustion from too much traveling. Confirming her ideas, Patricks doctor suggested that she slow down and get a hobby. If you cant slow down, he said to her, I can always give you a prescription for Valium.

After weeks of still not being able to ride or rock climbher favorite sportPatrick returned to her doctor, who did blood work, but found nothing obviously wrong. He told her not to worry. It wasnt until 1997 that she finally found out that she had a rare form of ovarian cancer called Micropapillary Serous Carcinoma. After the late discovery, Patrick endured seven surgeries and, at one point in 2001 after being flown to a hospital via flight for life, doctors told her she wouldnt live past six weeks.

------------------------------------------------------

Patrick did live, and she says, in large part it was due to her experiences in the mountains. She was strong from regularly biking and lifting weights, and she was mentally balanced after decades of rock climbing. The wilderness and leadership skills she gleaned in places like the Rocky Mountains prepared her for the greatest challenge of her lifesurviving that six-week ordeal in the hospital.

While on her deathbed in the ICU, a doctor inserted a blood gas line in her body, and it hurt like hell, she says. I snapped and got angry, and at that moment I came back into my body. She likens the feeling to being really scared after a rock climbing fall or when she has been stuck on the side of a mountain on a ledge in a thunderstorm. I would get scared and then angry, and that would act as a catalyst to get moving. I knew if I did not keep moving in the face of my disease that I would not make it.

Since her extraordinary recovery six years ago, Patrick continues to move rapidly forward. Not only does she still climb and play in the mountainsshe topped out on the Grand Teton after 22 hours of climbing through blizzard conditions in 2004but she also decided to make it her mission to raise awareness and money for the cancer that almost killed her. My lifes goal is to prevent as many women as possible from going through what I experienced, she says.

In the last few years Patrick has helped create an ovarian cancer website for the Johns Hopkins Medical Institute, and she regularly travels around the country on speaking engagements. Patricks crowning achievement is the non-profit HERA Foundation (Health, Empowerment, research, Advocacy), which she created in 2002. She organizes Climb For Life events around the country and in Mexico, which bring women and men together to rock climb, do yoga, watch climbing slide shows and films, and, most importantly, learn about and raise money for ovarian cancer.

Friend and Climb for Life volunteer, Deanne Pranke says that Patricks climbing events have been incredibly inspirational for thousands of people. Sean has brought ovarian cancer out in the open and empowered many women such as myself to take charge of our health and educate our loved ones and friends about this kind of cancer.

Adds Patrick, The need for perseverance forces women to reach deep inside themselves when they feel like they cant go further. The lessons you learn from climbing and taking care of yourself in the wilderness translate into successful life strategies on a day to day basis. In fact, Patrick has never seen a sport as empowering as climbing is for women. Often when Ive seen women get to the top of a route in the gym, the transformation on their face is phenomenal, she explains.

------------------------------------------------------

Sean Patricks wide smile greets the climbers as they stream into the third-floor room of REI Denver, spring 2004. Running her hand through a shock of white blonde hair, she says shes nervous when speaking publicly, but her voice is steady and vibrant as she talks about ovarian cancer and the HERA Climb for Life REI Road tour (now in its third year), sponsored by REI, Black Diamond, and HERA. She speaks to the audience with the fluency of someone who possesses a vast knowledge of the disease and the politics surrounding it.

After her diagnosis, Patrick became a research maven, reading everything she could find on the subject and hounding doctors all over the country. With her energetic and insistent attitude, shes penetrated the wall of scientific jargon to understand her disease. What she learned inspired her to reach out to others.

Since its inception, she says, the foundation has provided doctors with research grants; provided seed grants to a number of small communities, which have allowed them to offer immediate assistance to aid patients with travel, hotel rooms, and childcare while they are undergoing treatment; and established awareness programs throughout the United States.

Patrick has also convinced thousands of women and men to work with her. Among those women are famous alpinist Kitty Calhoun and salt Lake City, Utah, resident Hillary Silberman. Both women worked with Patrick to create a video highlighting the HERA Foundation and ovarian cancer.

According to Silberman, making the video and volunteering for HERA changed her life. Silbermans mother died in 2003 from ovarian cancer, and she says that she felt helpless in the face of her mothers illness. My involvement with HERA gave me the tools to work with to deal with my mothers death as well as people to connect with who understand where Im coming from.

By being involved and being proactive, Silberman explains, she has done something positive for others by presenting them with information. I have also done something positive for myself by beginning to think about what I needed to do to protect myself and get early detection.

With cancer affecting most of the female members of her family, Silberman is at a high risk for contracting the disease, although she doesnt currently have it. Her nurse practitioner tried to convince her not to worry, but Patrick and the Climb for Life events convinced Silberman to follow through on her own to seek the medical services she needs for early detection. The feeling of strength, perseverance and tenaciousness that climbing engenders made me not give up when professionals were telling me not to worry.

------------------------------------------------------

As with most female-specific diseases, says Patrick, ovarian cancer has typically been ignored by the medical industry. Despite the fact that it kills women of all ages and more women than all the other gynecological cancers combined, many doctors are ignorant of its symptoms and think the disease affects only the elderly. This, explains Patrick, partially results from the medical fields traditional focus on men and male-specific diseases.

For example, the Agency for Healthcare research and Quality found that although coronary heart disease (CHD) causes more than 250,000 deaths in women each year, much of the research in the last 20 years on CHD has either excluded women entirely or included only limited numbers of women.

Additionally, doctors treat women different than men in hospitals. According to a fall 2001 study published in the Journal of Law, medicine and Ethics, womens pain reports are taken less seriously than mens, and women receive less aggressive treatment than men for their pain. Also, women were more likely to have their pain reports discounted as emotional and therefore, not real.

I have had several experiences with this kind of dismissive treatment by both male and female doctors, says Patrick. It is a flaw in how medicine is taughtwomen complain, men dont, so they take mens complaints more seriously. To get the best treatment, you have to find a doctormale or female (one is not better than another in being more empathetic)that sees you as a person and not a statistical group.

Although Patrick seeks to change the way doctors view ovarian cancer and other women-specific diseases, she believes its more imperative to encourage women to take control of their own health. Ovarian cancer is not a silent killer, she says, the disease has symptoms, and its important that women are made aware of what they are. women who go to the doctor with gastrointestinal symptoms must make sure that ovarian cancer is ruled out.

Through climbing, Patrick believes that women can be taught to stand up for themselves. Not only do these events teach women self-reliance, but they are also places where we can turn our passion for climbing into a passion for making a difference.

I think success in climbing no matter what level you climb at5.4 to 5.14translates to successful life strategies, Patrick says. I want women who are empowered by the mountains to take this back into everyday life, and as it relates to the medical community, I want them to trust their intuition despite their doctors contention that they may not have a problem. In climbing and in life, trust yourself.

golf Swing Training Dust golf Dust works by spraying a spedcial powder on the hitting surface of your golf club. Then when you take a swing, you can tell exactly where the golf ball impacted the face of the golf club. Its a great golf impact indicator because you get immediate feedback and its very simple and easy to use. You can use golf dust on your woods or your irons, even on your putter.

How does golf Dust training work to improve your golf training accuracy? Simple - golf Dust will help your accuracy golf training because you can tell if you are actually hitting the golf ball exactly on the sweet spot. This is significant because hitting the sweet spot will give you maximum distance and accuracy.

We hear golf pros talking about the sweet spot all the time. What exactly is the sweet spot? The sweet spot is the area of the clubface that will deliver the maximum force through impact. It has to do with a law of physics that says force equals mass times acceleration. Use the force Luke.

When the golf club strikes the golf ball, there is some resistance that actually decelerates the clubface. Its actually a slight shock that you barely feel, unless of course you hit a fat shot and take a deep divot. Most of that shock is absorbed in the shaft.

Now back to creating accuracy and maximum force. The golf club is designed in such a way that a certain area of the clubface will absorb the maximum amount of shock. Hitting the sweet spot means you lose the least amount of force because the club experiences the least deceleration possible. Again, force equals mass time acceleration. The more force you impart to the ball, the farther it will go.

Now lets say you hit the ball off the toe of the club - youll hit a weak shot that goes to the right. Youve lost power because when the club impacted the ball, the club actually twisted slightly in your hands and decelerated. You lost accuracy because the shock of impact caused that slight twist in your hands and caused the ball to go to the right.

Its simple to demonstrate how the sweet spot works - Get out a putter and try this:

Grab your putter and hold it up in the air between two fingers. Now tap it on the center of the putter blade youll see an indicator where the sweet spot is located.

When you tap the putter on the sweet spot, youll see how it absorbs the impact and bounces straight back. From every action, there is an equal and opposite reaction.

Now try tapping the putter on either end of the putter face. See the difference? See how it wiggles? Did you notice how it didnt go back as far?

So how can golf Dust translate to golf training accuracy and shooting lower golf scores? If you learn to consistently hit all your putts on the sweet spot, youll putt the ball in the hole more often. The ball will roll straighter and its easier to control the distance because youre impact force will always be the same.

golf dust can help your putting because you can quickly tell if youre hitting the sweet spot or not. It youre hitting it off the toe, youll either be missing a lot of putts right and short or youll be overcompensating in your swing.

With Irons and Woods, the results of golf Dust are even more dramatic. For example, if you spray golf dust on your driver, you can quickly tell if youre hitting the ball too high or too low on the clubface. This can let you know if you should raise or lower your tee for optimal impact.

Simply hitting the sweet spot with your driver can increase your distance by 10 25 yards. The more important thing is that it will help you hit more fairways and get closer to the pin with your iron shots.

Now as a golf Training Aid golf Dust wont necessarily help you have a better swing, it will just give you immediate feedback to what is the cause of your improper ball flight.

Can Golfdust cure your slice? Golf Dust wont necessarily fix your slice in golf but it might show you that the reason youre hitting the ball weak and to the right is because you tend to hit the golf ball toward the toe of the club. Youre problem might not actually be slicing the golf ball but your position and set up. You may need to stand closer to the ball.

golf Dust is simply a golf impact indicator that will help you diagnose your golf swing problems. Its a great golf teaching aid for golf professionals who want to give their students a visual example of their swing faults.

You should also know that you cant use golf dust on your club in competition. The rules of golf prohibit you from doing anything to alter your club during a round.
