This is a nightmare of a question and one which is not easily answered without first responding with the question ‘what do you know about image post processing and pre-press?’, followed, usually in my case, by the whole book preamble on the history of photography. It serves little purpose. Most individuals in my experience of this subject, are impulse buyers who have swallowed the manufacturer carrot and purchase on the basis of product appearance and little understanding of the mechanics or specification. By the time I have gotten to Niepce, listeners are already bored stiff. You know the glazed eye look…
This aside, there are novices with a genuine interest and limited budgets to spend. So here goes.
Several years before I purchased my first flat bed scanner and at a time when I was building digital stock for the future digital archive, I used a local lab which had invested (early to mid 1990s) in some expensive kit. They had Agfa digital film recorders, a raft of Apple Mac computers, a Scitex flat bed and top-end Umax scanners. With all this stuff, the lab could meet the professional quality demands of its advertising agency client
Image Scan Quality
Resolution is the image quality measured in terms of how many pixels make up your image. It is commonly referred to as “ppi”; (pixels per inch). One of the common dilemmas when scanning photo transparencies to digitize them for use on a person’s website is how detailed of a scan do you need to provide your webmaster to post your imagery online. I’m going to sidestep the issue of image copyright concerns for the time being as I’ll cover that in an upcoming article on its own. However, because your images are to be viewed on a screen, all web graphics should be no larger than 72 ppi and thus anything higher has no improved effect, and only creates longer download times. This will also reduce what an individual could do with the image file if they had alternate motives.
Image Dimension Size
Pixels are the unit of measurement for the screen and most webmasters design a website to fit one of the standard display sizes. Based on statistics that can be looked up on the internet, we have found that most people today have their monitor’s set to display at least
To harness the potential of Photoshop in your image editing, consider making use of movie tutorials. This type of tutorial allows you to see how a given feature is used or effect is accomplished in real time, as the action is performed. You can even stop the video to go try it out in your own copy of Photoshop. Because of the ability to stop, rewind, and replay scenes in video tutorials, you can use them as a constant reference. If you do not have time or money to attend classes and seminars, video tutorials can be a great help in learning to use your copy of Photoshop.
Some video tutorials are available for free, others require some payment for the effort that has gone into them. These latter type are more likely to be professional. The saying goes that you get what you pay for, and this is still the case with Photoshop tutorials. However, even the free type of tutorial can be useful. They are readily available online, and can be used to find out if you like the video style of tutorial before you buy more professional video instructions. These tutorials may be offered
It is adding a great extra dimension to the hobby with an old camera but with today’s modern digital cameras that are running on low costs and with no need to develop the film. If you are doing a lot of photography then this will actually add up quite rapidly and you will be able to either save a lot of dollars or just be able to take a lot more pictures.
The most obvious way to control a digital camera is to use a servo with a camera pressing on the shutter button. You might have seen some really good photos taken with a Canon Digital Ixus camera using this exact method as this is a method that is commonly used around the world.
However this might not appeal to you as it interferes with the normal use of the camera. In this age of fly by wire it seems a bit agricultural to do it this way. But every man does it his own way and I am not to tell you how to take your pictures.
Now you might think: Is there no way to do this in an automatically and electronically
If you’re having difficulty understanding metering, then you’ll probably want to take up night photography as this is one of the types of photography where you don’t have to worry about your metering. You can forget about honeycomb, matrix, spot and multi-metering systems as these will not be utilized in night photography.
The best metering system that you’ll ever need for night photography is your eye coupled with some experience on your belt. Since we are no longer dealing with daylight, a metered reading is only as useful as a “starting point”.
There are so few factors in night photography that can make the metering system unreliable. It is because whenever you read meter systems, they work on the premise that the area being read has equal amounts of light and dark areas. If you’re metering with that premise then the system will not work 100%.
What you want to do is to simply start out with an aperture of 2 seconds with an aperture of around f/5.6 if your depth of field is not a priority. Should you need a longer exposure, just try the shutter. If your camera is able to go up
Light comes in two basic categories:
Direct light is what you have on a sunny day.
Diffused light is what you get on a cloudy day. The clouds act as a diffusion filter.
Think back to elementary school science. Light rays do not bend. If you point a flashlight, the light won’t bend around the corner of the building, you’d have to move the flashlight to see the side of the building.
Direct light (sunny day) creates deep, harsh shadows that have distinct edges.
Diffused light, (cloudy day) can be very bright but completely shadow less.
Generally speaking, diffused light is best for simple video production.
The easiest way to transform a direct light into a diffused one is by bouncing it off the ceiling or wall. Do this by simply placing the light near the wall (or ceiling) and pointing it toward the wall, not your subject. The light bounces off the wall and is diffused nicely. (Don’t get it too close though, I once burned a guy’s wallpaper cuz a 500 watt tungsten lamp get purdy hot. Oops.)
Bouncing a light is the quick,
When you have decided to give urban landscapes photography a try, you have to bring along a wide-angle lens, telephoto (zoom) lens, polarizing filer and a tripod. You need a wide-angle lens to capture wide shots while you need a zoom lens to capture distant details, for example, the cross of a cathedral. The polarizing filter will help to darken blue sky and remove reflections from non-metallic surfaces. Needless to day, the tripod is for low shutter speed usage.
One of the challenges when doing urban landscapes photography during weekdays and working hours are the people and traffic. These two elements will inevitably be part of your foreground images. To avoid this, you can do it on weekends. However, this may not be possible all the time if you have other commitment.
Since we cannot get rid of these two elements (people and traffic), we might as well use them as part of our composition. As recommended by Practical Photography (Apr 07 edition, page 36 by Chris Rutter), one of the recommended approach is to blur these moving objects. For slower moving objects such as the pedestrians, you can use a shutter speed of around 1/8
Digital photos are liked the most these days as they have reduced the loads of paper copies. Because of the mini-computed devices, it has become easier to carry and take digital forms of photos. Digital camera has thus surpassed the sale of film cameras. These cameras are updated version and include features to store and record images and pictures on a memory chip, of which the film cameras are deprived. There are several forms of them in the market ranging from mobile phones and PDAs to Hubble Space Telescope.
These, if deleted by chance or by anything can be recovered, restored, and maintained with use of software like Data doctor. The software can recover all missing and deleted photos from the hard drive or any USB media. It also fetches back pictures from disk partition and storage media. In digital photography, the number of pixels matter as they increase the quality of a photograph or an image.
High resolution gives a hint of the amount of detail captured, but it is just other factor to determine the quality. The Sigma SD14 camera functions on the Foveon technology. It is different from all other digicams. It is
