Editing

Today has been a day for editing some of the images that I have obtained over the last couple of weeks. I have not accomplished much today despite my efforts, as my computer decided that it did not want to play ball and proceeded to freeze on me a couple of times whilst I was in the process of editing. Fortunately for me, I managed not to loose the work after having to reboot my computer, so that was a huge relief for me.

The editing consisted of tidying up the images where the stitching had not been applied properly. In most cases this is due to the parallax.

Parallax in Photography

Parallax error can be seen when taking photos with many types of cameras, such as twin-lens reflex cameras and those including viewfinders (such as rangefinder cameras). In such cameras, the eye sees the subject through different optics (the viewfinder, or a second lens) than the one through which the photo is taken. As the viewfinder is often found above the lens of the camera, photos with parallax error are often slightly lower than intended, the classic example being the image of person with his or her head cropped off. This problem is addressed in single-lens reflex cameras, in which the viewfinder sees through the same lens through which the photo is taken (with the aid of a movable mirror), thus avoiding parallax error.

Parallax is also an issue in image stitching, such as for panoramas

I have a little way to go before my images are finished but I believe that paying attention to detail will pay off in the long run and I can be a bit of a perfectionist. Tomorrow I will be having a Photoshop Seminar with photographer Holger Pooten and hopefully he will be able to give me some advice and show me some new techniques. Here’s hoping that tomorrow will be a productive day!
