Camera Digital Technology - Sensors, Storage Space And Snapshot SharpnessBy Rika Susan
Camera digital technology: do you have to understand it to utilize it? Probably not, especially if you're using a consumer digital camera - a point-and-shoot - and you just want to get that holiday trip recorded for posterity...
On the other hand, it is quite useful to have a good grip on camera digital technology to get the best out of that little technological marvel!
For starters, it makes sense to know that the number of pictures you can take on your camera depends on the file format you select, and on your camera's storage capacity.
Camera digital technology generally works with two main formats, the JPG and the RAW file. The latter is for storing as much as possible original data per picture, to be adjusted later on a PC. The RAW format is of particular interest to professionals. RAW pictures often need nearly 10 times as much storage space as JPG files, so a casual photographer will generally choose to use JPG.
However, your camera might give you the option of selecting high quality JPG's or standard quality JPG's - the latter using less space, and mostly giving quite satisfactory results.
The camera will store the picture files on a card. A 256MB card can sometimes store more than 80 images of standard JPG size. If you're willing to spend more, new camera digital technology allows you to buy cards with 10 times more storage capacity.
Another aspect of camera digital technology which is useful to know about, is the way the images are captured. In stead of the film of well, film cameras, digital cameras have a silicon sensor with light-sensitive photosites (pixels) which capture the light information.
These sensors are often less precise than film when it comes to rendering detail in shadows and highlights. Camera digital technology therefore dictates that you should be careful not to "blow" your highlights. If they are not captured in the first place, you can't make any adjustments afterwards in your software processing.
To ensure you capture as much shadow and highlight detail as possible, and in a balanced way, camera digital technology offers you the use of a histogram. This handy tool is a little graph which indicates how the levels of brightness are distributed in an image. Many cameras show a histogram in real time, while you compose your image, giving you the opportunity to make exposure adjustments.
While digital camera lenses are essentially "old technology", it is useful to know that you can get excellent quality pictures from fairly inexpensive consumer cameras. This has once again to do with the sensor used in camera digital technology.
As the sensor in these point-and-shoots have a much smaller surface area than the 35mm film of a film camera, the former can get a much sharper and detailed image than a film camera with the same lens, due to the smaller focal area.
Camera digital technology has the major advantage of offering you stacks of opportunity to experiment with taking first-rate pictures, because you don't have to be concerned with the expenses relating to camera film.
So go out there and put the new camera digital technology to use!

Senior Portraits and The Senior Portrait Photography Studio
Studio Photography and Digital Backgrounds
Do you ever feel like you know just enough about Studio Photography to be dangerous? Let's see if we can fill in some of the gaps with the latest info from Studio Photography experts.
The article given here was written for Adobe Photoshop 5,6,7,CS, and Adobe Photoshop Elements 2 and 3.
Most photographers who are serious about improving their portrait taking skills have realized that a beautiful background can greatly enhance their photographs.
Muslins are a very popular choice among professionals. However, they can get very costly at several hundred dollars each. For the professional who is well established, this may not seem too much, but for the hobbyist, this may be a stretch.
A less costly alternative is a digital background. With a digital background, one can get the look and feel of a professional looking portrait without the additional cost of muslin.
Many Photography websites also sell digital backgrounds on cd. In some cases…as low as $15.00 dollars for an assorted collection. As with anything else…you usually get what you pay for. Some of these pre-made digital backgrounds are not worth the cd they’re printed on, but some of them are very beautifully made. Even so, you may be wondering how YOU can make your very own digital background. That being said, the following information will help guide you along the way.
Okay, let’s create a digital backdrop using Adobe Elements 2.0. We will create an 8x10 300dpi (dpi = dots per inch or ppi = pixels per inch) digital backdrop. For printing purposes, 300dpi is strongly recommended for a high quality print. This will also create a large file approximately 20.6megs.
Having a fast processor (Pentium 4 or Athlon XP) and at least 256megs of ram will definitely help. Also having your screen resolution on your monitor set to its highest setting 24 or 32bit will give the best results.
Okay let’s begin! If you haven’t already opened Photoshop Elements, do so now.
1. Click on File < New. When the window opens up,make sure to set it to 8x10 inches at 300dpi.
2. Make a copy of the background layer you just created by pressing Control-J on your keyboard. If you look at the bottom right corner of your monitor, you should see an exact copy of your background layer named layer 1.
3. Select the “foreground” color for your background by clicking on the foreground square on your toolbar… the black one. (Bottom left)
4. The Color Picker window should now be open. Select a light red by clicking on the top right corner of the color palette. Click ok.
5. Now select the “background” color by clicking on the background square on your toolbar… the white one. (Bottom right)
The best time to learn about Studio Photography is before you're in the thick of things. Wise readers will keep reading to earn some valuable Studio Photography experience while it's still free.
6. The Color Picker window should open again. Select a darker red by clicking halfway below the lighter red you previously chose. Click ok.
7. Now comes the fun part! Let’s put some clouds in there. On the top of your screen, click on Filter
8. First, make sure that layer 1 is not locked! Look at your layers palette on the bottom right of your screen. Do you see the little black “lock” icon? Make sure that the little white square to the left is NOT checked!
9. Okay, now press “m” on your keyboard. At the top left corner of your backdrop, click and drag your mouse to create a 2x3 inch square. If you do not see the ruler along side your backdrop, press “control-r” on your keyboard.
10. Press “v” on your keyboard. Your selection should now have little handles on all sides that you can click on to pull to any size you want. If you do not see any handles, click on “Show Bounding Box” at the top.
11. Click on the lower right handle in the corner and drag and stretch it to the bottom right corner of your backdrop.
12. Double click anywhere on the red backdrop to apply the resizing. Now press “L” on your keyboard then “control-d”.
Okay, now you should have a beautiful looking backdrop ready to use, but wait, there is still more we can do to take it to another level. You will be simply amazed at the results you will be getting in the next few steps. You may have noticed that many types of muslins on the market have painted on them what’s known, as a “hot spot”.
What is a hot spot? A hot spot is a circular area near the center of the backdrop that is lighter in color. Why is this there? It allows the subject to stand out and creates a vignette at the borders. This will greatly enhance your backdrop. Are you ready? Okay, let’s do it!
13.On the top, click on Filter-Render-Lighting Effects. Select “Omni” for your “Light Type” and move the slider for your intensity to 25. Now click on the middle handle in the circle and raise the circle just above the halfway point to where the person’s head will appear.Click ok.
Now you should have an amazing looking backdrop!

Introduction to Travel Photography
Introduction to Travel PhotographyBy John S
If you’re a traveler and a photographer you’re blessed with the opportunity of a lifetime to capture moments in time from throughout the world and allow others to experience the world through your photography. Your adventures will become others dreams and inspiration. Often a particular photograph could make someone want to follow in your footsteps. Just one photograph could trigger the travel bug in someone and the next thing you know, you, the photographer, and enhancing people’s lives through the use of your camera.
Besides the impact travel photography has on others, it’s also very rewarding to the travel photographer. Chances are you would have had a camera on you anyways, so why not apply the creative principles of art photography to help enhance the pictures you take.
How to take the best travel photographsThere are two types of travel photography.
1) The “stand in front of that sweetie” brand and the “spontaneous and interesting” brand. Unfortunately most travel photography falls into the former category. We’ve all seen this type of photographer before, and regrettably most of us are guilty of it as well. We will try and capture the shot of something for no other purpose than to just prove we were there. The result is an often scripted, uncomfortable, predictable and visually boring picture. These types of pictures clog photo albums. Page one; the family in front of a water fountain. Page 2; the family in front of a monument. Page 3; the family in front of a sign that says something only funny to tourist. Congratulations, you’ve taken the same shots, in the same position as thousands and sometimes millions of other people. Let’s now turn our attention to the other brand of travel photography, the spontaneous and interesting brand.
2) with this type of photography you are still free to capture the tourist site and you are still allowed to include yourself in the picture. However, there will be a stark difference in both composition and character engagement. Let’s say for example that you and your family have gone on a kayaking for the day. Some people may line the kayaks up, gear up and stand in front of the kayaks, throw their thumbs in the air and “click”. The picture is taken. When you get home to look at your shot you realize that the picture didn’t capture the peacefulness of kayaking, the calming backdrop of mountains or the scared look on sisters face when she had to duck under a log. You’ve simply captured proof that you’ve been there and done that. A better idea would be to have someone on shore (because you probably don’t want a camera in a kayak unless you’re very skilled), and have them take pictures of the action while its happening. Even if you have to recreate events, it is still better than the scripted and visually boring alternative. Obviously capturing the moment spontaneously is best, but recreation finds itself in second place if that’s the only other option.
Likewise if you’re in Rome and you’d like to get a picture of your friend and the Coliseum all in one, try quickly pulling out your camera while they are looking at the size of the structure and snap a shot of the wonder and curiosity in their eyes. Often this takes some preplanning with however you’re with. You will need to tell them; “Look, when I take out the camera I don’t want you to stop what you’re doing and “say cheese”. Just keep doing what you’re doing because I’m trying to capture our unpredictable and beautiful life as it unfolds”. It may take a couple of times before they stop turning and looking your way, but once you get this down pat as a team, your pictures will turn out much better.

Buying Your Child A Digital Camera - What You Need To Know
Buying Your Child A Digital Camera - What You Need To KnowBy Kevin Rockwell
Purchasing any gift item for your child is a mind-numbing task. You can never be sure whether they will like what you buy for them or not. So, when you want to buy a digital camera for your little kids, then there are lots of things, which you must know, which will help you (hopefully!) to get the right camera for your child.
One of the most important things for children is that the digital camera should be one of the latest available in the market. If it has been heavily advertised and people are talking about it, then it is even better. This gives children a sense of pride and also allows them to ‘show-off’ their possession to their friends.
Another factor, which is critical for children, is that the camera must look good. This is very, very important to them. It does not matter whether it has a big screen or small screen, whether it is 2 mega pixel or 1.5 mega pixel – the camera should have a smart shape, come in flashy colors or it can also look cute or funky. But, the camera should not look ‘boring’ or very ‘serious’ in nature. However good the functions might be, if the camera does not look good, it is most likely that your choice will get rejected.
The size is also important. Most children will definitely prefer a digital camera that is small and compact in size. The weight and size should be such that they are able to easily put the camera in their pocket or hang it by a string. Large and bulky models, even if they have better features are not advisable for children.
It is also necessary to remember that even though you might gift your child a digital camera to click photographs for school projects, they will be using it to take pictures of their friends. So, look for some ‘fun’ features in the digital camera. These can include colorful background images or sound effects, photographic effects that they can use to enhance the images taken by them.
One more thing is ease of use. It is important that the camera has a simple system through which children can easily take pictures quickly. However, you really do not need to worry about this aspect a lot because today’s children have been born in the digital era. They are able to pick up things much faster than you or me, so as long as the camera is good in all other aspects, even if its ‘click ability’ is a little confusing, it does not really matter. They are fast learners these days!
Last but not the least, is the price. While buying a digital camera for your child, it is understandable that you really do not want to spend a lot of money. There are lots of choices available in the market today. The price range starts from as low as $30 and can go up to $300. So, it really depends on how much you would like to spend on the camera. Start simple and upgrade if they grow out of the digital camera that you buy for them. Hey share them with the whole family!
