Check out these cool ways to edit your digital photos

By: Dan Brown

In Digital photography, enhancement is very helpful to help you edit your pictures. Sometimes an original looks so bad, it appears as if nothing can be done to help it. Not true! A couple commonly used enhancements are angle correction of slanted pictures and barrel and pincushion correction. The angle correction basically defines itself in the title. If the picture is slightly titled then the angle correction enhancement will help it out quite a bit. One thing the tool needs to have is anti-aliasing. Barrel and pincushion correction is used to fix slanted horizons that were caused by the camera being used to zoom up as far is could go. These enhancements are used mainly for generally annoying changes that some people wouldn't even notice unless it was dramatic, but are useful nonetheless.



What is re-sampling and how does it compare and differ from resizing? Both these tools are used to either enlarge or reduce a photo. Re-sampling is a little less heard of than resizing but a nice image editor will have it. The difference is this: re-sampling is actually the use of algorithms that you can select that will either re-calculate the amount of pixels (reducing the size of the image) or use interpolation to enlarge the photo. Re-sizing is a lot less complicated. All it does for enlarging is double the pixels and for reducing the image it just takes pixels out and sometimes completely deletes thin lines in the picture. Re-sampling is the preferred method for professionals because the image comes back clear and appearing unchanged. Resizing doesn't work as well; it is the preferred method for beginners and amateurs because it is quick and easy. The picture ends up being blocky and choppy and won't look as nice as re-sampling. Most image editors will have the option of both.



When you are editing your images you are going to want to change the format and the size of the image altogether. There are two types of compressing images. One is the Lossy compressing style. This is more the conservative image compressor, it takes up the least space and is easily uploaded to the web or to an email program. Generally this will save in the .jpg format, one of the most commonly seen everywhere. Lossless on the other hand has the disadvantage of not being able to choose the size you want the image. However, you will be able keep a smaller image of the original version. Common to its name, lossless compressions do not lose any part of the image. The format this compression normally saves to is .png though it can save to a bmp or rle which are less common formats. In the end which one you choose is up to whether you don't care about the original image or you really care and don't want anything lost, your pic.



Having a half decent image viewer is just as important as actually changing them. Having the ability to easily access and change your images in a process that isn't complicated to you is essential. There should be some definite functions, like the viewer should easily be adapt to your needs, be able to enhance photos and be beneficial to your use. Aquiring photos and adding them to your database should be quite easy. Managing EXIF data and being able to batch process is helpful. A couple recommended viewers would be Photophilia and Zoner Photo Studio. These are both amateur accessible and function filled. Helpful functions that you could have would be the batch function, editing function, a file filter would be nice and the image size via pixels.



When you want to you don't have do edit a whole bunch of images at a time. Having something that will control all the changes you want made to a large amount of images. If you want the images resizes it is very easy. There are bunch of types of batch processors. Each has its ups and downs, some photo viewers even have batch software that comes with them. A good example of what you want a batch processor to is have a large amount of images in one directory ready to go. Then you tell the software what to do, e.g. 50 images that need to be resized to 100 x 50 pixels then add a watermark and compress the image to 5kb to be transferred in email. Then you tell the program to run and within the next hour your images will be all ready to go.



A handy tool to have if you don't intend to collect thousands of pictures is a digital photo album. This is handy because you can add descriptions and make sure you get a nice looking album for people to look at. This is different from a photo view because it actually stores all the photos no matter where they are located. The program will actually go and find all your photos. This would not be recommended if you have more than 2,000 photos because if a file gets corrupted you could lose all your pictures. An online viewer would actually be useful because then after you used a batch processor you could upload them all to the site and have just as nice of an album online. In the end it is up to you whether even want an album in the first place.



Lots of questions come in everyday about different types of batch software, and other image processes here are a couple: Q: My photos have EXIF data, but no "taken date", how can it be ? A: Basic information like the date, aperture, shutter speed etc should be written into the EXIF data of the photo by any camera. "Normally" differences between camera makes should only be with the "makernotes". Makernotes are mostly completely different with different makes.Nevertheless some cameras seem to save EXIF data without saving the "taken date". The user who did report the problem did send me one of his photos. While the other EXIF fields (camera name, aperture, shutter speed etc...) were present, the EXIF date fields were empty. The camera of the user is a Nikon Coolpix 880. Now I do not pretend that every Coolpix 880 shows the same problem. It may be one out of a given series, it may only be the Coolpix 880's sold in a specific Country, it may even be that some fake (and unperfect) Coolpix 880's have found their way to the market. Who knows? Q: I can't find any way of getting my digital camera to work on my pc. A: With most digital cameras you get a pc software. This software is intended to be used to get the photos onto the pc and to do some other tasks too.Indeed most of these programs are not very convenient and you can easily go without ever using them. Easy ways to acquire your photos (i.e. get the photos onto the computer) are described at PC camera software or how to by-pass them to acquire photos.
