If you are a novice to photography, the equipment may seem very confusing, especially the camera. It was difficult enough working out the terminology before the digital revolution, but now it is practically impossible. Digital cameras are dedicated microcomputers and just as difficult for the uninitiated to comprehend.

Even a medium grade $300 digital camera will almost certainly have 40-50 adjustable controls and every one of those might have four or five settings. Most of those controls the amateur will almost certainly never appreciate and never change from default, but the camera will still take decent photographs. However, it will take even better ones if you do make use of them.

Here follows an explanation of some of the more frequent terms that you will come across if you go to buy a digital camera.

Megapixels is the rating used to convey the resolution of the photograph that a digital camera is able to take. A pixel is a dot of colour and a picture is created from dots of colour, therefore, the more pixels in a photograph, the higher the resolution of that picture and resolution creates sharpness. So the higher the number of megapixels the better.

Cheap digital cameras might have a resolution of 4 megapixels (4,000,000) whereas an costly one might have 36 megapixels. If you just look at your photos in small format, say, a couple of inches by a few inches, on your camera or computer screen, the difference may not be apparent, but if you go to a larger size or have your photos printed on paper, you will see the difference.

The disadvantage of a higher resolution is that it takes more storage space. Obviously it takes two times as much space to store 8 megapixels as it does to store 4, so the higher the resolution the more memory your camera and computer will require. This is not a big difficulty unless you plan on taking thousands of photographs.

Zoom is the camera’s ability to get a closer shot of the topic without really going nearer to it. Digital cameras often have two types of zoom: digital zoom and optical zoom. Digital zoom just refers to magnifying the pixels, so an image that has been treated with high digital zoom will look grainy, unless you have lots of pixels in the picture.

However, computer image handling software has more ability to apply digital zoom than any camera, so the camera’s digital zoom is largely irrelevant, since you will almost certainly edit your best photos on the computer anyway. While purchasing a digital camera, pay more attention to the amount of optical zoom.

Optical zoom refers to a moving lens, just like you would adjust a pair of binoculars, a telescope or a magnifying glass. Optical zoom is very useful because the quality of the image is not impaired by this zoom. The higher the better for optical zoom, however, be wary of total zoom, which is optical and digital zoom added together. You have to know how much of each.

There are such a lot of tanning lotions, sprays and creams on the market that you could never try them all – you simply would not have the time. However, there is one that appears to have taken the tanning industry by storm and that is the tanning lotion they call California Tan or Cal Tan.

In fact, California Tan has been available for approximately 25 years, so it is not a new-comer by any means. Tanning lotions are judged on several levels including tingle factor, bronzing effect, cooling effect and sunblock factor. The effect that you find important is up to you obviously, but the most important factor should be safety.

California Tan is a slow-acting tanning lotion, which means that you should not expect fast results. California Tan tanning lotion is intended to be applied each day either to maintain your present tan or to slowly create a suntanned, glowing skin tone. A good tanning lotion will not dry the skin out, so it will include a moisturizer.

In fact, the best tanning creams will bronze your skin, moisturize it and filter out the sun’s harmful UV rays. It is especially vital to have sunblock built into any cream or lotion that you intend rubbing into your skin on a daily basis.

Whichever tanning lotion you buy make certain that it is capable of taking care of your skin and compatible with your skin type. This can be an expensive and drawn out process, because the only way to test a lotion in the right manner is to rub some into an region of your skin that is fairly sensitive but that is not always on display. Somewhere like your inner thigh.

Maybe you could test a friend’s tanning lotion or use a few different ones every time you go to the tanning salon until you find one that is right for you. Then it is best to stay with what you know will not harm your skin type, because regrettably, what works for your friend may bring you out in blotches or make that awful orange skin colour.

Check the label to see what the lotion contains. There ought to be a couple of plant or fruit extracts that you recognize to be beneficial (again which ones are good for you depend on your skin type) and there should be a few vitamins like vitamins A and E.

If you go with a tanning lotion intended for daily use keep in mind that even a compatible cream could damage your skin after prolonged usage, so make sure that you keep an eye on your skin carefully, wash off the tanning lotion at the end of the day and deep clean your skin with a moisturizer, particularly in sensitive areas like your face, neck, thighs and the sides of your chest.

If California Tan tanning lotion passes all these checks on your skin, it will be worth trying, but do take care and do not listen too much to the advice of friends and sales personnel – at the end of the day, it is only you who has to walk around in your skin.

The injuries associated with electricity are the result of electrocution. Electrocution can result in: minor shocks, which can result in other accidents like falls; medium shocks, which can result in burns and even critical burns and major shocks which can result in death as in some American prisons.

The victim can receive an electric shock by coming into contact with a live wire or by the electricity from a live source arcing out – essentially finding earth through that person’s body. The majority of electric shocks are not serious and are over before you know that it has happened but they are scary afterwards.

A fall resulting from a mild electric shock probably has greater potential to be fatal than the shock itself. For example, if you were changing a light bulb from a step ladder and you reckoned that the switch was off, but it was not, you may receive a short sharp shock, and it could make you to fall off the ladder and break your back.

On the other hand, high voltage electric shocks can result in burns deep in human tissue whilst leaving just minor signs of the injury on the outside. It is very important not to get complacent about electricity, because, like the open sea, it does not suffer fools gladly. Here are a couple of electrical safety tips to help keep you safe.

1] Always inspect power tools for damage and broken plugs or frayed cords before use. You might have damaged it last time you used it yet got away with it that time

2] If you are working in the same area as others, particularly on a building site, do not leave your leads trailing across the floor – try to tape them to a wall or a bench, because people may step on them, run wheel barrows over them or spill water on them.

3] Always use the correct gauge cable and fuse for your equipment.

4] If anything gets warm when you are using it, be aware that it might be a sign of an approaching difficulty. Leave warm equipment or sockets to cool down, if it occurs again, get them checked by an electrician. Do not over load electrical sockets.

5] Strive to use a dry wooden ladder if you are working near cables, because timber does not conduct electricity.

6] If you are using any apparatus that produces heat or strong light, do not train it on anything that could catch fire.

7] Fit fast-reacting circuit breakers between your apparatus and the source of electricity to reduce the shock that you might get. These devices detect a faulty earth and switch the appliance off in milliseconds.

If your appliance or electrical equipment has a button for checking the earth, use it every day and if you are going to work on a light socket, an electrical socket or the fuse box, test it first with one of those electrical screwdrivers with a small bulb in it. You poke it into the circuitry and the bulb lights up, you have just had a narrow escape. Be more cautious next time!

A storm can be stressful for your outdoor fish, especially for large koi carp, which, being large, possibly do not have many places to hide. However, if you have designed your koi fish pond well, you will have taken this into account when your constructed the pond. Likewise, the pond must be deep enough for your fish to be able to get well beneath the choppy surface layer.

If you prepared for the storm, you possibly put a net over the fish pond, so the first thing you need to do after the storm is clear up any fallen debris and take away the net, so that you can get a good look at your fish and what occurred to them. They may be a bit stressed, so move unhurriedly and try hard not to frighten them. Stress is a killer in the animal world as well as in ours.

Did you take the added precaution of sand-bagging the edges of your pond to stop it over-flowing and the fish swimming away? If so, take away the sand bags, so that you can get a closer look.

Now you can get a good look at the upheaval, if there is any. Use a net to quietly skim off any leaves that have blown under the netting and onto the pond. If any plants have been uprooted, put them back where they should be. In general, put the pond back as it used to be, so that the fish feel at home. Again, move unhurriedly and try not to put your fish under any more stress.

If you need to carry out major structural repairs, you could place your koi in a child’s plastic paddling pool until you can sort the issue out. Put the pool in a shaded area and fold the netting over it several times so that the fish can not get out and cats and birds cannot get in. If you can aerate the water with a pump so much the better.

Put a few plants in there with them for cover and feed sparingly. if the repairs will take a long time, you could ask your local pet shop to take them away for a week or whatever. You will have to pay board and lodgings, but it is preferable to losing your prized koi carp.

Once any repairs have been carried out, you ought to check the water quality, which could have been affected by debris falling into the pond or by your repairs. Rain, especially acid rain, can have quite an effect, especially if it rained for a long time.

First check the water for nitrates. If the levels are unacceptable (see the testing kit for details), you ought to normalize them. If the levels are extremely high, first remove the plants from the water.

Then analyze the KH levels. If they are low, say, below 100, then you could add a cup of baking soda per 1,000 gallons of water and check again. Whatever you do, the fastest way to de-stress your fish is to reinstate their environment to what it used to be with sparkling water to swim in.

It is compulsory in most Western countries for employers to provide safety glasses or safety goggles and it is compulsory for employees to wear them when instructed to. It has been proven that wearing safety glasses at work considerably reduces the number of accidents and accidents are costly.

The Occupational Safety and Health Administration (OSHA) reported that eye injuries cost US businesses about $467 million each and every year, so a few dozen pairs of safety glasses would definitely recoup their cost. However, it is also important to use safety glasses that were designed to protect the eyes of wearers in precise professions.

One of the concerns with safety glasses is that they fog up. This means that employees often have to take off their glasses to de-mist them, which lessens the effectiveness of the glasses. Stopping fogging or misting is a major difficulty for makers of safety glasses.

The reason for of fogging is a lack of air flow. This is normally only a difficulty with goggles, because they tend to be a tighter fit so they get warmer, which vaporizes any moisture created by the eyes or by perspiration. It can also be caused by a low ambient temperature.

Consequently the first step towards solving the problem of fogging or misting in safety glasses is to find out where and why it happens. Fogging will generally occur when the worker moves from a hot region to a cold one, in hot humid zones or where the employee’s body temperature is higher than the ambient temperature.

The first approach ought to be to opt for lenses that will deal with those environments or conditions. Lenses can be coated with anti-fogging or anti-misting coatings. These coatings are applied at the time of manufacture and ought to last the lifetime of the safety glasses.

These coatings will prevent the build up of water droplets on the lenses permitting clear vision. There are other coatings that can be applied too, so it is a question of seeing what types of coatings are obtainable from your supplier.

It is worth bearing in mind that not all anti-fog coatings are effective under all the conditions where fogging can occur, so you should be precise when explaining to your supplier why you need anti-fog lenses.

If someone has to enter an area where fogging often happens, supplying an anti-fog cloth to wipe on their lenses is a short term help. These cloths are alright to use on most lenses, so it is wise to enquire. The effects ought to continue for a number of hours.

If personnel move from one zone to another and have to change their safety glasses from zone to zone, they should be shown how to recognize safety glasses with the special coatings. Lenses that have been treated at the factory with an anti fog coating are often stamped with the letters ‘AF’.

It is worth learning how to deal with fogged safety glasses, because it can save a great deal of frustration, misery and money, if you just spend a little time getting the correct safety equipment.
