Is Editing Digital Photos Images good for Image Quality?

Monday, May 18th, 2009

People that say tiff is the most appropriate format for picture editing are not as right as they claim.

In fact, when you first got your pictures from the camera, transforming them is never the first step. The image is stoked onto your hard drive in a compressed format, named JPG. The image that is read by the virtual memory is uncompressed. Format issues can only arise after editing what you want and saving the final image. Compressing during a save does not affect the quality of the initial uncompressed image with the changes it now has that is still located in the virtual memory and will remain there until you close the editing program. The only quality changes are visible in the saved JPG, with because of the compression it’s normal to have less information.

It’s normal to make intermediary saves when changing a photo’s appearance because you never know what could go wrong. These intermediary save will always be done under a format that is especially made for editing, that saves both quality and allows changes to become editable. If by instance you are using Photoshop to make changes, then save the intermediary files as psd, witch is the typical Adobe Photoshop format. Failing to do this will return an intermediary save that acts just like another image. And finally, when you think you are done, choose a final saving format for the image from the conventional ones.

Some people believe that if you crop in any way an image you will lose quality. Cropping means that you can rotate, enlarge, resize the picture using certain algorithms that are known by your editing program. It’s obvious that enlarging algorithms that will enlarge only by pulling pixels until they become visible are algorithms that decrease image quality. photo printing online

Is Editing Digital Photography Images Safe for Image Quality?

Sunday, May 17th, 2009

Some say that after you have your high quality, high resolution pictures and you want to put them on your hard drive and work on them for a little bit, it’s best to transform first the Jpeg files that come from you camera to tiff or other appropriate format, because working on jpegs might cause you to loose quality and color.

But transforming from JPG to something else has no relevancy as a first step of editing digital photography. Usually camera save pictures as JPG, and this is the format you will see on your hard drive But the Pc’s virtual memory will unravel the image when you open it. Only at the time you want to save the edited image from you PC’s virtual memory you might raise the problem of file format: jpg, gif, tiff, png and so on. Compressing during a save does not affect the quality of the initial uncompressed image with the changes it now has that is still located in the virtual memory and will remain there until you close the editing program. What you have in the computer memory is not affected by a save during editing, as long as you use a different name for the new file.

This problem is questioned by people that make saves during editing so they have a good restoring point that can show some progresses. Make the intermediary saves in a digital photography format that stores high quality, maybe even uncompressed images , but also leaves the edited file intact, without flattening and closing layers. So this basically means you should save the intermediary images in the format that is specific to your photo editing software. If you do this, when you mess up your work and return to the saved point, you will be able to follow all the previously taken steps. Only at the end save the image in as a standard picture file, JPG, TIFF, GIF, depending on its purpose.

Another myth that is not true is the one that states cropping a digital photography image can modify its pixels. Cropping means that you can rotate, enlarge, resize the picture using certain algorithms that are known by your editing program. Some algorithms eliminate extra unnecessary pixels, and others will simply enlarge existing pixels. photo printing online

Digital Photos in The Colder Months

Sunday, May 17th, 2009

Cold, snow, blisters, moist and temperature variations are just some of the characteristics of winter. Unfortunately, all these winter signs affect the way you should regard digital photography. But the most important thing is to feel good; it’s essential to be comfortable while you’re photographing, if you are in front of the subject of your photographic life and all you can think of are your wet shocks, the pain in your ear and how nice a hot tea would feel right now, then the picture is ruined. if you plan on shooting pictures of winter sports of wonderful snowy mountains, wear something that won’t make you remember how cold it really is It’s better to wear several stratus of clothes because the inside temperature will be maintained at constant values for a longer time. If you feet and head are warm, you will endure cold temperatures easier.

Wear some boots that are water resistant and also take a pair of warm gloves with you. The gloves must not be too swelled. It’s impossible to push the tiny buttons on your digital photography camera with frozen fingers, but try pushing them with large ski gloves. Do you think it’s possible ? try to imagine the scene you are about to photograph in your head and when you are ready to take the picture, watch the small camera LCD and take off the gloves quickly and briefly, just to push the button. This way you avoid getting cold or freezing hands and you do everything that needs to be done with gloves on, except for the final part that involves pushing a tiny button.

it’s so cold that you are worried for you digital camera, and you should be, because it’s sensible to such low temperature. Most plastic parts that compose the camera do not maintain the same durability when temperatures go too low and might easily brake. Do not open the camera and change batteries in such cold days, the simple fact that you are breathing over it could produce water vapors and ruin the whole device. Also, do not change memory cards while you are outside and the weather is too cold or too moist. The reasons are the same as in the case of battery changing.

If you are taking pictures of snowy landscapes, do not let the camera auto detect the setting. Taking snow pictures must be done manually because snow can end up grey if the camera darkens it to emphasis the subject. Also, don’t be reluctant about using flash, I know it seems highly improbable to be needed because snow causes your eyes to hurt, that’s how bright and luminous it is. snapfish review

A bit about Digital Photography Cameras

Thursday, May 14th, 2009

The biggest advantage when buying new technologies cameras is the fact that viewing pictures costs nothing. When choosing a digital camera, many important factors can intervene, but the most important one is, invariably, the photographer. Or shall we say, the photographer’s skills. A few criteria were stated for the inexperienced under of digital cameras Only professional photographers can go shopping without further advices.

Deciding with model of digital photography devices if the one that best suits your needs might seem difficult because there are so many different possibilities. Don’t get drawn in by the low price of a certain camera without checking twice the specifications. Of course you must not overpay for something, so consider price also, but after a proper evaluation.

Easy menus and functions must be the first thing to look for. Then, the next thing to look for is the sensor dimension, or the mega pixel number. Sensor width and mega pixel numbers are closely related but you don’t really want a camera that has over 3 mega pixels because they are way too expensive for personal needs. So, be moderate when choosing the sensor dimensions. For vacation pictures or family albums you can safely choose a 3 mega pixel camera, it will return beautiful pictures.

Think about the optic system also when choosing a digital photo photography device. On cameras that can make big photos, it’s crucial to have lenses that are reliable enough to bring quality to big formats. Most modern digital cameras have lenses signed by certain famous lens producing brand. Also, read the optic zoom values, not the digital zoom. Digital zooming means only that the camera is digitally adjusting the image and enlarging pixels in order to give you a closer look, therefore returning a lower quality image. The optic zoom must be over 2x, to see the image at least doubled, you don’t need enormous zooms that make the camera cost very much.

The way we manage the menus and pictures can be called the camera digital package. Modern cameras even have special functions that modify pictures as you take them. Just make sure the display is big enough and the buttons are easily accessible, then browse the menu and see if it provides easy options and accessibility to important functions. print digital photos
