Computer Care: Tips for the best summer snapshots | ||
POSTED: August 23, 2013 9:04 p.m.
This summer I spent more time with my camera than my computer. As a camp photographer up in the mountains of White County, I shot more than 20,000 photos. To make them look good, I had to edit them quickly and judiciously -- good enough for parental scrutiny.
Although the dog days of summer are behind us, Labor Day is just around the corner and chances are you still have some pictures to take.
I’ve seen more poor quality images posted to Facebook recently; some were dark, some washed out, some simply blurry or in need of cropping. Even with the ubiquitous cellphone camera, quality photos can be created with little effort.
The primary thing to consider when taking pictures is where your light is. Ideally, you don’t want to shoot into the sun, but rather have it over your shoulder.
Even if you’re outdoors, don’t be afraid to use a flash. It will remove facial shadows and brighten up your pictures. Keep in mind though, the pop-up flash on cameras will reach only about 6 feet before its light dissipates.
In order to get the most from the light that is available, your camera will read it with a meter.
In DSLRs, most point-and-shoots and many cellphone cams, you control the meter. Usually, if you place the crosshairs in your viewfinder on the face of your subject and press the shutter release button half-way down, you not only place your subject in focus, but take a reading of the light on them as well.
The thing is to hold onto that meter reading. Readjust your view to take the photo without releasing pressure on that button. Otherwise your pals will be in shadows, all blurry with the lake behind them sharply illuminated.
After you get that reading, continue to frame your image, then finish pressing the shutter release button.
When composing a picture, look at it as if it were a print. Be critical. Are there trees or poles coming out of your subjects’ heads? Are they in the light? Are there extraneous objects in the photos, like people or vehicles?
It’s always a good idea to take a few extra shots to ensure one will come out. Some may be too dark or light; others may have someone not smiling or their eyes closed. There were close to a thousand shots at camp I didn’t use.
Edit out the bad shots on the fly, before you get home. This will cut down the editing process.
Just about every shot needs some editing, whether it be cropping out extra sky or people, or adding contrast or light to the image.
However you alter it, the paramount rule of editing is not to save over the original photo. If you are working on photo 123.jpg, rename the edited image as 123a.jpg and save it in your docs or photo folder as opposed to the card it came from. This way, should you inadvertently ruin a picture, you will always have the original to try it again.
Photoshop is the granddaddy of photo editors, but there are many good free editors online.
GIMP is an open-source image editor. It is the closest thing you can get to Photoshop without paying anything. There’s a learning curve, but it’s free. Find it at www.gimp.org.
Easier to use and free, are IrfanView, at www.irfanview.com and PhoXo at www.phoxo.com. Both will provide the basics of adjusting light and contrast with crop tools and more.
Without loading an app to your computer, you can use online editors, like FotoFlexer found atwww.fotoflexer.com and Pixlr, at www. pixlr.com. They save you the trouble of an installation.
Experiment with being creative with your photography. Try the different modes your camera has to offer. They change the exposure settings so you don’t have to. Most have a panoramic mode, one for sports and another for portraits. Looks at the icons on your camera’s mode dial or display and you’ll figure it out.
If you want to experiment with manual settings, just remember the F-stop (aperture opening) works in direct relation to the shutter speed. If you raise one, lower the other. You’ll get basically the same picture with a little different results.
Although the same amount of light comes through, a faster speed freezes action better and a smaller aperture yields a greater depth of field (more things in focus).
Want create the effect of motion? Try panning your subject. If you have a moving subject like a car, a runner or bike rider, move you camera with it as you shoot the picture. Your subject will be in focus with a blurred background, looking as if he/she is really moving. Try it a few times and you’ll easily perfect this technique.
So if you still have pictures to take this weekend or haven’t really done anything with images from the Fourth of July yet, now you can get busy with the knowledge of how to shoot better photos and how to fix those that didn’t come out as you’d expected.

Since the early 1990s, I’ve had half a dozen desktop computers, five laptops, various printers, a couple of faxes, a plethora of dumb phones and a couple of smartphones. But just this week I got my first tablet computer. As I once initially thought, I had no need for a computer (my dedicated Smith Corona Word Processor was just fine for a writer), I also thought I didn’t need a tablet. I was wrong.
Many times I needed a computer at a client’s home but didn’t feel like packing up my laptop in its case, grabbing the cord and throwing it in the car. Having a tablet is infinitely easier.
If it had 3G, I’d be happier, but it was an extra hundred bucks and my carrier doesn’t allow a la carte data usage on extra devices anyway. So I’m stuck with just Wi-Fi, which is really OK.
I ruled out Apple products mainly because I believe they are just too expensive. I considered a Windows tablet (also another extra $100), but went with what I already have on my phone: Android. It’s easy to use, has an abundance of free apps and is the cheapest type tablet on the market.
For less than $200, I got a mobile computer that, although won’t replace my laptop, will certainly complement it. Much of what I did on my phone and some of what I did on my computers, I now do on the tablet, and do it with mobility.
It’s a great tool for business. It allows me to chat, connect to a Windows computer remotely and I can now check email on the fly without having to use the crowded keyboard on my phone. It also allows me to browse the Web and actually see where I’m going and speak my search criteria, should I prefer not to type it.
I have a memo and to-do list, and I’m finally able to use a calendar that’s large enough to actually see . I can take decent videos and photos with the tablet, although I mainly use my DSLR for that.
It comes preloaded with Polaris Office Suite, that allows you to create and edit .doc, .docx text documents as well as .xls, .xlsx spreadsheets and .ppt or .pptx presentations.
On the light side, I can watch movies, TV shows or YouTube videos with my 7-inch Samsung Galaxy Tab 2 model with its high quality 1024 x 600 display. I can read e-books, use it as a universal remote for all of my electronic devices and listen to online music. There are a ton of games available. Admittedly, I do subject myself to the occasional Mahjong challenge.
Granted, it obviously lacks the surround sound audio quality of a home theater, but for a device that’s less than 3/8 inches thick, the sound is surprisingly good and the video quality is fantastic.
It has a dual-core, 1 GHz processor with 8 GB of flash memory which allows it to go from page to page flawlessly.
The tablet, like many, also has dual cameras, so I can video chat with my girls or clients, if necessary.
After I logged on to my Galaxy Tab for the first time, all my cloud-based docs and photos were there for me to view because it synced to my Google Docs and Dropbox accounts. That was a nice surprise.
There are some drawbacks though, to using a tablet. There is obviously no keyboard; it uses a touch-screen. It ‘s smaller than a laptop, but larger than a phone.
There is a photo editor installed on it and although the Google Play Store has thousands of apps to download, other editors included, I do miss my Photoshop.
I also miss the availability of a USB port. That was a disappointment. I will have to resort to either sending my tablet files electronically or put them on the Micro SD card I added to the system. It only came with 8 GB of on-board storage space, so I added an additional 16 GB (it takes ups to 32GB). It does have Bluetooth, though.
