Digital Cameras

No, alkaline batteries are "primary" cells*, and cannot be recharged. NiMH (Nickel-Metal Hydride) are "secondary" cells*, and can be recharged several hundred times. If you have a camera that takes available NiMH cells, they not only save money in the long run, but they perform much better in cameras than alkalines, which have less than 1/2 the life (and then you throw them away) of a NiMH (which you can re-use). I use Sanyo Eneloops, and am totally satisfied with them. They do not hold as much energy as the "high energy" cells, but they don't discharge in the camera in a month, either. I also like the charger that comes with them, which is one of the few inexpensive ones I've seen that will charge a single cell at a time.

*Don't ask me. That's just what they're called.

Photography relies on principles of light, optics, and technology determined through scientific research and understanding. Concepts such as exposure, focal length, and depth of field are all based on scientific principles. Advances in science have also driven the development of camera technology, leading to improvements in image quality and usability.

Silver iodide (AgI) is an ionic compound with strong attractions between oppositely charged ions, resulting in a higher melting point. Vanillin (C8H8O3) is a covalent compound with weaker intermolecular forces, leading to a lower melting point. Ionic compounds typically have higher melting points compared to covalent compounds due to their stronger bonding interactions.

The nautilus is the animal that uses a pinhole-type eye structure for vision. This primitive eye design helps the nautilus sense light and detect predators in its ocean habitat.

Saturn was the outermost planet known until William Herschel discovered Uranus in the late 18th Century, so unless you count this as ancient, it would be inaccurate to say that the ancients could 'see' the planets beyond Saturn.

Telescopes are first definitely attested in the early 17th Century. Photography in the modern sense (using a camera to record sharp images on a light-sensitive film, as opposed to more basic forms like the pinhole camera) didn't exist until the early 19th Century.

I'm guessing that your question arises from the (quite sensible) assumption that all of the planets were named by the ancients, but this is not the case. The 'trans-Saturnian' (if you'll pardon the term) planets were named after Greek and Roman deities by later astronomers.

Interestingly, Uranus and Pluto are named after Greek gods, rather than the Roman gods that give the other planets their names. I suppose that 'Caelus' and 'Dis Pater' didn't quite have the same ring to them.

Hope this helps.

Yes, as long as you use an NiCd charger, but you really shouldn't. NiMh has twice the capacity of NiCd and it is less expensive. NiMh also contains no toxic materials so it is better for the environment.

Abstract photography are taken of very dramatic images. It relies on more sense of form, color, and flow than it does on detail. Abstract photography minimalism digital and film photography of places and things from a different perspective.

An oblique aerial photograph is a type of photograph taken from an aircraft at an angle, rather than directly overhead. This perspective allows for more detailed views of objects and landscapes, making them useful for mapping, surveillance, and other applications.

Many interviewers ask questions about past experience, new ideas you have had, and problem solving skills. They ask these questions to find out about the person and if they would be a good fit for the company. Answers should be concise and honest as they highlight your skills.

Elements used in photography include lighting, composition, framing, perspective, color, texture, and contrast. These elements are manipulated by the photographer to create visually appealing and interesting images.

In this context, "rr" typically stands for "race replica," indicating that the product is a replica of a vehicle used in racing, with high-performance features and design elements inspired by racing models. So, "Fireblade RR" would refer to a model of a motorcycle that is a race replica of a high-performance racing bike in the Fireblade series.

My granddaughter (age 2) drew, with a blue felt pen, all over her aunt's wedding pictures (2 of them). I tried Windex, hairspray and carpet cleaner but nothing touched it. Then I tried a non-acetone nailpolish remover. This did the trick! Worked like a charm. This took all of the ink off and didn't touch the finish (these were professional photographs). I don't know if I would attempt this on pictures straight from an ink-jet printer, though.

The change in energy taken in refers to the difference between the energy absorbed and the initial energy level of a system. It can be calculated by subtracting the initial energy from the final energy. This change in energy is important for understanding how energy is transferred or transformed within a system.

Chemistry is essential in photography for developing film and creating prints. Chemical reactions are used to expose light-sensitive materials, such as silver halide crystals in film, to create an image. Understanding the chemical principles behind these processes helps photographers control the look and quality of their photographs.

I purchased 4 rechargeable batteries plus battery charger July 2006. I take many photos for my eBay business and have found that in the last few weeks when I recharge the batteries, they only last for a few photos. I thought rechargeable batteries lastest more than 2 years. Can someone let me know the life of rechargeable batteries. Thank you.

Yes, given the vast number of stars and planets in the universe, it is statistically likely that there are other Earth-like planets that have not yet been observed. Many exoplanets may exist beyond our current detection capabilities, waiting to be discovered.

# Hire a private investigator to follow you and have them watch out for and take pictures of them. # Set up hidded cameras in the places that you think that they hide Don't let them keep doing this. Much Luv, A

Before using a rechargeable battery for the first time, it's recommended to fully charge it to establish a full cycle and optimize its performance. Make sure to follow the manufacturer's instructions for charging times and methods to ensure the battery's longevity and efficiency.

A photomicrograph is an image that is taken through a microscope to visualize objects that are too small to be seen by the naked eye. This technique is commonly used in fields such as biology, medicine, and material science to study microscopic structures and organisms. The image produced is often magnified to allow for detailed observations.

By warmer, they mean that the color leans toward yellow and orange. Daylight film (or a digital camera set to daylight) are balanced so that light such as you see outdoors or through a window will appear natural or white. This is the wonderful thing about digital: between frames, you can switch the color balance to incandescent (tungsten) so an image taken near an incandescent lamp will appear less yellow. If you shoot raw, then the color balance is not affected until later in your editor.

To demonstrate this, you can take a picture of a person with one side facing a window and the other side facing a table lamp (with a regular bulb - not fluorescent). Shoot one picture with the camera set to daylight and one picture with the camera set to incandescent/tungsten. Then compare. You can take the same shots and play with the color balance in program like Photoshop. There are good examples in books and magazines, but it's good to do it yourself so you know your camera settings.

Watch out for fluorescent bulbs and the kind of lights like you see in gymnasiums. To the human eye, they appear fairly white, but they are changing color and brightness (flickering) at 60 times a second. So you want a shutter speed that is 1/60 or longer to avoid problems. Even then, they aren't really quite white. Most digital cameras have a fluorescent setting to take care of the difference. Some films handle this better than others.

MRI (magnetic resonance imaging) scans are known for providing high quality images of soft tissues in the brain. They offer excellent detail and are commonly used to visualize structures like the brain's gray and white matter, as well as any abnormalities in soft tissues.

Radiator cleaner has a chemical that is a mild acid. A person can make a less caustic radiator cleaner by using a product called Sal Soda. Sal Soda is found in the laundry detergent aisle of most grocery stores. After draining the radiator, put in 2 cups of Sal Soda, and fill with water. Put the cap on the radiator and run the vehicle for about 10 miles. Then drain and refill with the appropriate antifreeze.

The colors in the sky are a result of the scattering of sunlight by particles in the Earth's atmosphere. Shorter wavelengths like blue and violet are scattered more than longer ones, giving the sky its blue color during the day. At sunrise and sunset, the sun's light has to pass through more of the atmosphere, scattering more colors and creating the vibrant red, orange, and pink hues we see.
