PHOTO RETOUCHING,
USE ON THE WEB OF MY PICTURES
The methods of shooting pictures having been detailed, I now will say some words in the way I proceed to prepare my photographs in order to be able to post them on my website.
I use a simple and efficient freeware to retouch (the least possible) and to compress my photographs. There are several ones, downloadable on the Web.
I retouch as little as possible, primarily to modify a little bit light and contrast, to remove some details which may deteriorate the black background or to mask holes made by slugs in the petals of the blooms.
Example of photo retouching
Schlumbergera x "Lysa'
comment: The piece of the bloom in the top right-hand corner is of no interest and disturbs the subject.
It's better to erase it, which gives the following picture.
Schlumbergera x "Lysa' (retouched picture)
comment: In this second picture, the main subject better stands out.

use on the Web
My pictures taken in “JPEG fine” have a size of 4256 x 2832 pixels for a resolution of 300ppp (ideal for printing). Each photograph corresponds to a file of 2.5 to 4Mo according to the composition of the image.
To post them on to my website which is sometimes read with little sophisticated computers, I reduce dimensions of the photographs to 639 x 425 pixels with a resolution of 72ppp, unsuitable for printing, but sufficient for the observation on a computer screen. With the help of this compression, each photograph corresponds to a file of 20 to 40Ko.

Pour les intégrer à mon site qui est parfois lu avec des ordinateurs peu sophistiqués, je réduis les dimensions des photos à 639 x 425 pixels avec une résolution de 72ppp, impropre à l'impression, mais suffisante pour l'observation sur un écran d'ordinateur. Moyennant cette compression, chaque photo correspond à un fichier de 20 à 40Ko
And, last but not least, a page about some technical points of photography.........
