Digital Photography: History and Tips
Sunday, May 31st, 2009Although the history of digital photography isn’t very long, digital photography has already transformed how people take and view photos.
Before digital photography, most photos had been viewed as prints. Today, however, the majority of photos are edited and viewed on computers. Digital photography allows a photographer to develop his own film by using digital printing.
Yet, while digital cameras have taken the photography world by storm, film cameras have their advantages.
The History of Digital Photography
While most people may believe the history of digital photography goes back only ten or fifteen years, digital photography had been around for years before the first digital cameras were available to the public.
The history of digital cameras began as early as the 1980s, when digital photography replaced traditional film in astronomy. Digital cameras capture light better than film plates.
Since their introduction, commercial digital cameras have largely replaced manual cameras, as photographers can more easily upload, edit and email their pictures.
Digital photography printing allows photographers to create high quality prints in their own homes. As the history of digital photography progresses, expect to see even more options and features added to digital cameras.
Digital Photography Tips
Generally, digital photography tips aren’t different from film camera tips. The rules of basic photography composition and lighting remain the same. However, some tips can improve your digital photographs:
- Be Fearless : If you’ve got a large memory card, you can take multiple photos, review them instantly through the LCD screen and delete the shots you don’t want. This saves time and money that traditional film development demands. This unique feature of digital photography has made amateur photographers less concerned with how many shots they take. Because they have the freedom to take more photos, they have a better chance of catching that perfect shot.
- Read the Manual : While this advice is hardly unique to digital cameras, it remains one of the most important digital photography tips. Your camera may include macro features, various lighting settings, video camera capabilities and more. You’ll get the most use out of your camera’s features if you read the manual and learn how to use them.
- Experiment : A digital camera’s LCD screen lets people quickly review photos, allowing photographers to experiment with their camera’s settings. Would that photo look best as a landscape or an action shot? What happens if the lighting is set to overcast on a clear day? By experimenting with digital camera settings, people are discovering how to get unusual effects in their photos. If an experiment doesn’t work, delete the flawed photo.
- Use Your Self-Timer: One of the most under-used features in every digital camera is the self-timer. The self-timer delays the firing of the shutter after the button is pushed. There’s really nothing like getting everyone, including the photographer, in the shot. Plus, then you don’t run the risk of handing over your beloved camera to a stranger who may or may not get the shot you want and may or may not run off, camera in hand! Just line up the shot you want, activate the self-timer and hop in the picture. Usually you’ll have up to ten second to do so. Your memories will be all the better for it.
- Warm Up Your Tones: Often, professional photographers do not like to take photos in the sunlight. But you can overcome the issues that come along with that by changing a featire on your digital camera. If you adjust your white balance setting from “auto” to “cloudy,” you’ll automatically increase the balance of reds and yellows and the result will be warmer pictures.
- Head Outdoors: It may sound crazy, but feel free to use your flash for outdoor photos. Wedding photographers have been doing it for years! In your “flash on” or “fill flash” mode, the camera will expose the background first, and then add just enough light to expose your subject. Both the foreground and the background will be equally exposed and your photos will look like a pro took them. But remember, flashes often have a range of only about ten feet.
- Use a Tripod: In the past, tripods have been bulky, annoying and difficult to use. But those days are over. There are a few brands out there now that fold up and fit nicely in a pocket or purse. So you can get that professional quality without having to drag along a load of equipment.
When to Avoid Digital Photography
The history of digital photography has been so successful that you might wonder why anyone would still use film. Yet, traditional film has advantages over digital photography in particular circumstances.
Many photojournalists prefer to use traditional film. Although a digital camera lets a photographer quickly edit his photos, photojournalists build their reputations on the accuracy of their photographs. While some photojournalists use digital cameras, others prefer to use film so they can prove an image has not been altered.
For similar reasons, film is more admissible in court than digital photography, as there is less chance that someone has tampered with photographic evidence. While the camera may not lie, a software-editing program can!
Another issue with digital cameras is that they are more sensitive to cold and dampness than film cameras. As a result, film remains the choice of photographers working where bitter cold or wet conditions could damage a digital camera.
Some photographers simply prefer to use film, maintaining that digital photographs lack the detail and “feel” of film. In some ways, these arguments correspond to the “CD vs. vinyl” debate that began with the introduction of compact discs.
Digital Photography Versus Film
So which is better, digital photography or film? Compare the advantages of each:
Digital Photography Advantages
- Digital cameras are usually smaller than film cameras.
- Digital cameras can embed metadata into the image file (time, date, camera settings, etc.).
- Digital image files can be backed up and copied.
- Digital images can be altered with editing software for specific effects.
- Digital photography enables you to experiment without concern for time or the cost of developing flawed pictures.
- Digital printing can be done from a home computer with either a standard or digital printer.
- LCD screens on digital cameras allow for instant picture review and deletion.
- Many digital cameras have AV-out capabilities for television viewing.
- Photographers can print certain pictures and not others.
- Some digital cameras allow you to lock files to avoid accidental deletion.
Advantages of Film Cameras
- Film cameras are less expensive than digital cameras of the same quality.
- Film cameras are more durable in outdoor environments and adverse conditions.
- Film cameras can work without batteries.
- Film is harder to manipulate than digital images, ensuring the integrity of the original images.
- Some film types (infrared film, for example) have no digital counterpart.
Although digital cameras probably won’t completely replace film, their versatility and unique features make them an excellent choice for the amateur photographer.
Wedding Photography
Monday, May 25th, 2009Researching wedding photographers online first can save a lot of time before setting up any actual appointments.
View different photographers’ portfolios and read about their experience and approach — from this, you’ll quickly be able to tell if this is someone with whom you share a similar vision.
Ask how many weddings the photographer has done and whether or not he or she has photographed at your wedding venue. Familiarity with the space ahead of time will allow for more efficiency on the part of the photographer, who will be able to plan for different shots and situations unique to that venue.
Also, make sure that the photographer you choose will be the one who will actually be photographing your wedding. If you’re dealing with a large company who has several photographers available, they may send whomever is available on your wedding date. Be sure to get this in writing, as part of your contract with the photography company. (more…)
Photographic cameras
Monday, August 18th, 2008
The camera or camera obscura is the image-forming device, and photographic film or a silicon electronic image sensor is the sensing medium. The respective recording medium can be the film itself, or a digital electronic or magnetic memory.
Photographers control the camera and lens to “expose” the light recording material (such as film) to the required amount of light to form a “latent image” (on film) or “raw file” (in digital cameras) which, after appropriate processing, is converted to a usable image. Digital cameras replace film with an electronic image sensor based on light-sensitive electronics such as charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) technology. The resulting digital image is stored electronically, but can be reproduced on paper or film.
In all but certain specialized cameras, the process of obtaining a usable exposure must involve the use, manually or automatically, of a few controls to ensure the photograph is clear, sharp and well illuminated. The controls usually include but are not limited to the following:
- Focus of the lens
- Aperture of the lens – adjustment of the iris, measured as f-number, which controls the amount of light passing through the lens. Aperture also has an effect on focus and depth of field, namely, the smaller the opening [aperture], the less light but the greater the depth of field–that is, the greater the range within which objects appear to be sharply focused.
- Shutter speed – adjustment of the speed (often expressed either as fractions of seconds or as an angle, with mechanical shutters) of the shutter to control the amount of time during which the imaging medium is exposed to light for each exposure. Shutter speed may be used to control the amount of light striking the image plane; ‘faster’ shutter speeds (that is, those of shorter duration) decrease both the amount of light and the amount of image blurring from subject motion or camera motion.
- White balance – on digital cameras, electronic compensation for the color temperature associated with a given set of lighting conditions, ensuring that white light is registered as such on the imaging chip and therefore that the colors in the frame will appear natural. On mechanical, film-based cameras, this function is served by the operator’s choice of film stock. In addition to using white balance to register natural coloration of the image, photographers may employ white balance to aesthetic end, for example white balancing to a blue object in order to obtain a warm color temperature.
- Metering – measurement of exposure at a midtone so that highlights and shadows are exposed according to the photographer’s wishes. Many modern cameras feature this ability, though it is traditionally accomplished with the use of a separate light metering device. To translate the amount of light into a usable aperture and shutter speed, the meter needs to input the sensitivity of the film or sensor to light. Thus there needs to be a setting for “film speed” or ISO sensitivity.
- ISO speed – traditionally used to “tell the camera” the film speed of the selected film on film cameras, ISO speeds are employed on modern digital cameras as an indication of the system’s gain from light to numerical output and to control the automatic exposure system. A correct combination of ISO speed, aperture, and shutter speed leads to an image that is neither too dark nor too light.
- Auto-focus point – on some cameras, the selection of a point in the imaging frame upon which the auto-focus system will attempt to focus. Many Single-lens reflex cameras (SLR) feature multiple auto-focus points in the viewfinder.
Many other elements of the imaging device itself may have a pronounced effect on the quality and/or aesthetic effect of a given photograph; among them are:
- Focal length and type of lens (telephoto or “long” lens, macro, wide angle, fisheye, or zoom)
- Filters or scrims placed between the subject and the light recording material, either in front of or behind the lens
- Inherent sensitivity of the medium to light intensity and color/wavelengths.
- The nature of the light recording material, for example its resolution as measured in pixels or grains of silver halide.
