I’m going to start my first scuba diving class on Friday and was hoping i could get some tips first. What mistakes did you make and what should i do to avoid them? That sort of thing would be great. The first class is just going to be a classroom, but the one on Saturday we actually go in the water.

If you dream of getting away from it all and relaxing on the Caribbean coast, a holiday in Guardalavaca, Cuba, could be just what you are looking for. Located near Holguin on the northeast coast of Cuba, Guardalavaca is something of a hidden gem when it comes to Cuban beach resorts. The beach is fantastic, the resort has plenty of activities to keep you occupied and Guardalavaca’s hotels are top notch, but the resort remains quiet, secluded and unspoilt, making it ideal for a relaxing beach vacation. Here are a few highlights for a Guardalavaca holiday.

The Beaches

Most people come to Guardalavaca for one thing and one thing only - time on the beach. As though it weren’t enough for a resort to have one beautiful beach, while you are on a Guardalavaca holiday you can choose from three - Guardalavaca beach itself, Esmerelda beach, and Playa Pesquero. There’s even a mini train that connects Guardalavaca beach to Esmerelda, making it easy to move between the two.

All three beaches feature pristine white sand that slopes gently into clear water, dotted with the occasional tree to provide a spot of shade. The presence of the coral reef at Guardalavaca keeps the water calm most of the time, making it perfect for families and gentle swimming. Catamarans, pedalos and other common beach activities are all available for those who would like to do more than sunbathe.

Reef Diving

Out of all the diving spots in Cuba, Guardalavaca is a real highlight for scuba enthusiasts due to the expansive coral reef, located a few miles offshore. Teeming with wildlife, the reef is a wonder to explore while scuba diving, with plenty of caves and sheer drops to see. If you tire of the coral reefs themselves, there are a number of shipwrecks that can also be seen. If you are interested in scuba diving, the resort has several diving centres who can arrange trips and equipment rental for the best dive sites.

Swimming with Dolphins

Swimming with dolphins can be an amazing experience, and if you are on holiday in Guardalavaca you will have the perfect opportunity to take part in this unique activity. Close to the resort is the Acuario Cayo Naranjo aquarium, where you can see spectacular dolphin, seal and walrus shows, and then swim with the dolphins yourself. The trainers will teach you how to get the dolphins to splash and clap, and there is also the chance to “surf” on the dolphins at the end of your swim. People of all ages are able to take part, and life jackets are provided.

Deep Sea Fishing

Deep sea fishing has been associated with Cuba ever since Ernest Hemingway (who was a keen hunter and fisherman when he wasn’t writing books) made the island his home in the 1930s, and the Cuban waters are rich with tuna, barracuda, sailfish, snapper, grouper, and many other kinds of fish. Those on holiday in Guardalavaca can take part in this exciting and demanding activity, and you don’t need to be a veteran fisherman to do it. Experienced crews can teach you the basics and take you out, and the concentration of fish around the reef makes Guardalavaca a great place to go for deep sea fishing trips.

I just bought an underwater camera and the suggested ISO is 200. THe camera has an internal flash but woudln’t it be better to use a higher speed film to capture more light and color? Wouldn’t ISO 400 or 800 better?

naomi b asked:


It looks good, as resort quieter than Sharm but worried diving and snorkelling not as good. And do I need to book diving in advance?

Digital photography is a booming business and is slowly going to take over the film camera market. Compact digital cameras are the most popular and common of the camera types. To get a better quality picture you need to increase the number of pixels, so the cameras with more mega pixels will have a sharper image. Underwater digital cameras are small and lightweight, and the quality is comparable to film if you go for the higher resolution shots. Digital pictures have improved dramatically, and are now incredibly clear. The main problem that most have is that after the picture is taken many people don’t develop the pictures or don’t have a a way to do it.

How exactly does it differ from the traditional camera? Up to the point when the image is captured, the process is the same in both. When you release the shutter the mirror moves out of the way and the image is captured in the same way as any digital camera. Zooming in on a subject works by cropping some of the image out of the picture. The thing to remember is the higher the resolution, the more realistic the image is, matching closest what the actual image is. The image is then enlarged to fill the camera frame, by doing this you will loose the quality of the photograph. If an image is too bright or too dark you can re-take the image.

Digital cameras are not that expensive today a 2 mega pixel camera can be had for less than $50. Also important to note is the memory capacity of the camera. In other words, how many pictures will the camera hold? Understanding a little bit about how pictures are recorded on a digital camera and then subsequently saved on a computer is critical but fairly simple even for a beginner. The key to getting the best possible digital pictures is to make sure the right camera is bought. Digital cameras are becoming more and more popular. Whether your pictures are good or bad it does not matter, with a digital camera you have full control.

In burst mode the camera shoots a fast series of photos for as long as the shutter button is held down or until the camera’s memory is full. In this mode the camera writes the photos to a temporary memory which is very fast but small. When the shutter button is released or the memory is full the camera starts the slow process of writing the photos to the flash memory. Memory is also a very important issue to consider.

In terms of features it may not have any more than a simple point and shoot model. Picture quality is normally an improvement from the more basic cameras. The price of a digital camera printer is lowering whilst the quality is increasing. As far as image quality is concerned, there are a couple factors - picture resolution, presence of noise in the camera, dynamic range, and the color quality of the image. Depending on the camera purchased and the accuracy of the settings, the quality can rival and sometimes even surpass a regular 35mm camera.

Basically, a mega pixel is capable of storing a million bits of information about a photo. Because the digital SLR cameras are more professional, they come with a hefty price tag.

Thailand is sandwiched between The Gulf of Thailand on its eastern coastline and the vast expanse of the Andaman Sea on its western coast. It is in these body of waters that scuba divers can explore the marine life of the Indian Ocean and the Pacific Ocean without having to cross continents.

The waters in Thailand have one of the richest and diverse marine life in the world because conditions here for coral growth is almost perfect with an average temperature of 28C all year round and fantastic underwater visibility.

Because of these almost ideal scuba diving conditions and attractions, the scuba diving industry in Thailand is thriving robustly with the proliferation of first class scuba diving facilities, services and diving schools.

When you throw in what the tourist industry has to offer in Thailand such as fantastic entertainment, a spread of accommodations, hotels and resorts for every budget and Thailand’s renowned delightful cuisines, you can be assured of an enjoyable scuba diving vacation.

The Gulf of Thailand has hundreds of islands on its 1,840km (1,143 miles) long coast. The gulf is a shallow bowl shaped body of water separated from the South China Sea by a pair of underwater ridges that extend from Vietnam on one side and Malaysia to the other.

The sea bed bottom here is mostly mud mixed with sand and shells. Corals are usually found around the fringes of the gulf islands. There are several rivers in the north bringing enough sediment and freshwater to inhibit coral growth until to the south or the eastern side of the Gulf of Thailand.

The underwater scenery in the gulf is perhaps not as visually appealing as those of the Andaman Sea as it has slightly less variety of marine life. Marine parks such as the Ang Thong Marine Park include spectacularly formed limestone islands with lush rainforest covering them and many of these islands are actually uninhabited.

World famous resorts of Pattaya, Phuket and Koh Samui offer excellent scuba diving facilities as well as other reacreations and entertaiment.

The Andaman Sea was already thriving thousands of years ago with Chinese, European, Thai and Indian trading vessels plying its waters. Today, the Andaman Sea is more of a playground for dive boats and sailing yachts rather than for trading vessels.

One of the better known playgrounds for divers in the Andaman and is often rated amongst the top scuba diving destinations in the world are the Similan Islands. Divers can explore Similan, the Surin Islands and the Mergui Archipelago in liveaboard diving cruises.

Thailand’s Andaman Sea stretches 870km (541 miles) from Tarutao National Park on the border of Malaysia to the Surin Islands on the border of Myanmar (formerly known as Burma). It is part of the Indian Ocean and is separated from the Bay of Bengal by the Andaman-Nicobar Ridge. Quaint formations of granite outcrops can be senn in the Surin and Similan Islands.

Other island groups such as Koh Phi Phi are shaped by massive limestone and calcium carbonates since prehistoric time.

The only problem when you travel to Thailand for scuba diving is where to start your diving vacation since there are so many excellent dive spots to choose from and you will be spoilt for choice.
