Recently I have been revisiting Macrophotography. However, most of my pictures had a common problem: the lack of depth of field (DOF). Even in very small objects, with my current gear (I always shoot with natural light), I don't get the whole object focused....

I am compiling my latest editions in black and white, to create image galleries. Tonight I prepared a selection of black and white macrophotographs, as I indicated in a previous post. I hope you like them... Of course, if you are interested in buying...

Recently, two new camera anouncements have been made, with several new features, among them the removal of the Bayer filter in front of the camera sensor. On one side, the Leica M-Monochrom, developed to take only black-and-white pictures. This camera...

Well, just when I have defined all contents for my book (I can't seem to see the end), I find several posts related to the "Pseudogrey" concept. Normal grayscale images are coded in 8 bits in a single channel (one byte per pixel). This way, up to 256...

About five months ago I wrote a post on the presentation of TriggerTrap (a programmable digital camera shutter based on the Arduino open platform). Well, since then, people at TriggerTrap seem to be working quite hard, and only last Monday, April 30th,...

A missing point in this blog was the creation of short tutorials as edition examples. Well, you got it. Here you have the first one... In this case, i will play just with colour. I will use a picture of my daughter (I'm proud of both my daughter and the...

In all edition programs, you can find selection tools that allow you to pick a part of the image to apply changes (colour, filters, size...) locally, independently from the rest of the picture. At this point, you may already know that you can make a rectangular...

A couple of days ago I posted an article on the separation of colours to produce the rainbow. I also suggested some application in photography: the use of polarised filters to remove glare and to boost colour saturation. However, as in most cases, there...

(comes from here) More physics... An interesting piece of information, sun light comes polarized to us. All colours (all wave lengths) "vibrate" in a same way: Electromagnetic fields theory speaks about two oscillating, perpendicular fields, an electric...

The legend There is an Irish legend (with some variations...) speaking of Leprechaun, an elf you will find ath the end of the rainbow, whom you may force to disclose where does he keep his cauldron, full of gold coins... Simplified version states that...

I have presented several ways to add frames to our photographies and improve them, in a series of posts in this blog. As a result, you may get more attractive images to your public. However, there was still an open point: the classic approach to composition....

Proposals made so far were based in the increase of canvas size until the final dimensions and aspect ratio were achieved, with more or less color effects. However, we have another possibility: to work "inwards"... Work with layers To do so, we will need...

To finish this series of posts on image framing with GIMP, I wanted to review some advanced ideas: Enlarge asymmetrically Basic concept is to enlarge the canvas (typically in the last step) in an asymmetrical way, so that more space is available (for...

In a previous post, I described the way to add a simple frame to pictures, in order to improve their presentation (in paper or online) possibilities. However, this process may be too simple sometimes. Even when the frame itself should not draw the attention...

A simple visual trick to improve the presentation of your photographies is to add a frame to them. In GIMP, you can do this very easily with the canvas resizing option. This post will show you how. Some calculations... For example, I asume you will want...

As I commented in previous posts, the way photographic paper reacted to traditional colouring techniques depended on the amount of chemicals remaining after processing. Thus light areas took slightly different colours from mid tones and dark ones. In...

In some ocasions, I tried to do some direct colouring of a black-and-white photography with multiply option, a really easy technique, as you could read in some previous post. However, sometimes the result in the screen is not matching the desired effect...

I am checking the options provided by Over-blog. One of the most attractive ones (at this moment) is the possibility of directly selling my work - in this case, I'm thinking of my photographies. Inside my random images (you may see them in my blog's landing...

Since a few years already, a trend in photo edition is the increase of the dynamic range of pictures (HDR - High Dynamic Range). It is the way to use all available sensitivity range of the camera, or even to go some steps ahead by combining several images,...
