![]() ![]() With burnt-out details there is nothing to do, the detail is lost. In post processing I make the photo lighter as in reality. In case of bird photography many cases I try to underexpose the bird, to have more contrast and get rid of unwanted reflections or burnt-out details. What is it ? It is used to make a photo, or parts of the photo lighter or darker. In Gimp or Photoshop or Lightroom there is a function called curves. In Gimp curves can be found in menu Colors-Curves In some cases you may remove some saturation or make the photo black and white by desaturating. Not always needed but can add to the photo quality. To desaturate the photo to make it black and white it is possible in Menu Colors-Desaturate, there are three different methods you can choose which you prefer. If we add contrast usually boost saturation as well. In Gimp add saturation can be possible in menu Colors-Hue saturation by simply moving a slider. Sharpening in Gimp is in Menu Filter-Enhance-sharpenīasic sharpening does what it means, makes the image looking sharper, more crisp, showing more detail. I get the +40 contrast photo and add +20 sharpening. If we want less detail in some cases we can use blur or Gaussian blur. Most cases I use the normal sharpening which usually don’t give halos around the edges but not enhance contrast, just makes the picture looks more detailed. The unsharp mask add contrast as well, but makes halos around the edges, it is better to save an otherwise very un sharp but somehow interesting photo. There are two types of sharpening the normal one and the unsharp mask. In Gimp sharpening can be found in Filters-Enhance-Sharpening or Filters Enhance-Unsharp mask. The photo definitely better than before I think, but not as sharp as I like to. In this case I like strong contrast, but the last one is too much for my taste. The level of contrast added is personal preference, and can be different to different pictures.īelow this is the original image as it comes out of a 3.2 MP Olympus compact camera. Better prime lenses give much better contrast usually. I usually add some contrast in camera as well depending on lenses. If the light levels are not ideal usually contrast is lower. The main reason a picture look flat or uninteresting in many cases not sharpness but lack of contrast. In Gimp after opening the image we go to Colors-Brightness Contrast and after only move the slider in a required amount. In some cases portrait setting (higher than wide frame) works better. Other thing with cropping in wide angle shots or landscapes you can make as many partly different images from a single photo as you want. By experimenting you can develop a system how much you can crop to maintain quality. I mostly crop in bird photographs, where usually hard to get as close as I want, and usually use high iso for high shutter speed. ![]() If you crop too much you lose definition and can magnify noise levels. Light rays also can make interesting shapes or patterns which is not visible as much when we make the photo. Some cases disturbing things like cigarettes or garbage in the corners of the landscape picture or other things only visible on a computer. Fill the frame is the usual command but try to fill the frame with a Wren which is walnut-sized bird. I try to make pictures that cropping is not needed afterwards but many cases it is needed. In Gimp crop can be accessed in Tools-Transform tools-Crop or Shift+C to make it quicker There are newer versions now with many changes. I used the 2.6 version for this tutorial. At the beginning the GIMP perhaps little awkward need to learn and get used to it, but it is a high level program. The process can be done with many other software as well, the basics are usually the same. GIMP is a completely free software you can download and you can use afterwards without paying anything. If you like the picture without post processing no need to make it worse, or spend the valuable time to change. It is important to be on top of the process meaning you know how you want your photo to look like. You make little level of change after more and compare what you like. To know this level I suggest experimenting. In each case it is very important to stop at a reasonable level of post processing otherwise the photo will look overprocessed/unnatural. This tutorial can be useful for somebody who does not post process pictures yet, for more experienced people can be very basic. These are the main things I look at, the whole process can be done in a minute. I like to do post processing quickly, and effectively. Prefer to make photos instead in interesting places. I don’t like to spend too much time with post processing photos. Basic post processing with GIMP in 5 simple steps ![]()
