12 TOP Google+ Photographs for January 1. Tales Of The Vets and an update about Klaus It has been a crazy last 48 hours. First of all thanks everybody for the warm well wishes for my pooch Klaus on the post here I really appreciate it a great deal and so does he. I haven't been around much lately because of what is going on with him and thought that I would take a few this morning to update you all. The experience at the vet was absolutely scary. It was a very trying experience for myself and for Klaus. We also found out that he has arthritis very bad in his spine. I have been spending a great deal of time with him.
I tell ya, I was pretty convinced I wasn't going to be coming home with my best friend. Thanks everybody! D-sign « Ivaincrea’s Zeblog alias Igwane the blog. All About Digital Photos. What Print Shops Really Want In a nutshell, what any print shop really wants is a digital image of sufficient pixel dimensions to be able to meet their required pixels per inch requirement (usually 300 ppi) at the dimensions of the printed image. The latter is critical, to find out if your image meets their ppi criteria, you have to know the destined printed size. For example, using the 300 ppi criteria, if the image is to be printed 8 inches in size, then your digital image has to be a minimum of 2,400 pixels in that dimension - it's simple arithmetic (2400 pixels / 300 ppi = 8 inches). That's it! (except for the other photographic considerations listed below). Although this website is about digital photos - if you're creating a digital image by scanning - then DPI does count - you have to set the DPI of the scan to meet the required PPI the print shop wants at the dimensions it is to be printed.
For details about this please see the scanning page. What Print Shops Really Need. Adobe Photoshop Image Size Dialog Box. A point of confusion is how programs like Adobe Photoshop presents the image size. It is the miscomprehension of this presentation that has often led to the erroneous belief that the ppi/dpi number in a digital photo somehow relates to digital image resolution/quality.
The following image is of the "Adobe Photoshop > Image > Image Size" dialog box (Adobe Photoshop CS5) as it might typically look when you load in a photo directly from your camera. In the top part, in the Pixel Dimensions section are the number of pixels that make up the horizontal and vertical dimensions of the image.
In this case 5184 pixels horizontally by 3456 pixels vertically. The next section Document Size is where the confusion lies and miscomprehensions start. In this image we see a different number in the Document Size "Resolution". So, for digital photographers, the "document size" section is there simply for your convenience, to see what the paper size might be if you printed to a specified ppi. The Myth of DPI. Many people seem to get hung up on the DPI (dots per inch) or PPI (pixels per inch) setting within a digital photo as a measure of the quality of those photos. To set the record straight, the DPI/PPI setting within a digital photo has NOTHING to do with digital image quality!
The resolution of a digital image is its pixels (usually expressed as megapixels). The PPI of a paper print IS a measure of quality (of the paper print, not of the digital photo) - but it has nothing (in real world terms) to do with the DPI/PPI setting within the photo. Confused? If you've read the sections titled "What is a Digital Photo" and "What is a High Resolution Photo" you'll know that there are four main factors that determine image quality: 1) The size (in pixels) of the digital image. 2) The quality of the recording device (camera's optics and sensor, scanner's sensor). 3) The digital format it is stored in (lossless vs lossy compression). 4) The technical proficiency and the "eye" of the photographer.

Forum photo / Un petit dossier sur les bases de la composition d'une image. Oui, ça me donne envie d'illustrer la "fameuse" règle des tiers.Pour ceux qui ne connaissent pas, il suffit de diviser en 3 lignes son cadre, en vertical comme en horizontal, et aux intersections se trouvent les "points chauds" de l'image.C'est à dire ceux vers lesquels notre cerveau, via notre oeil, tend à s'intéresser le plus.
Bien souvent, placer le sujet (ou l'élément marquant du sujet, comme les yeux ou la tête) sur un de ces points chauds tend à rendre la composition plus harmonieuse.De même, en paysage l'horizon gagne a être positionné sur une de ces lignes. Inversement, un élément inutile à l'image ne doit pas être positionné sur un de ces points, ou il attirerait l'attention. Et, sauf sujet symétrique, reflets, et quelques cas particuliers, il est conseillé d'éviter de positionner son sujet en plein milieu du milieu du cadre.
