| I take the above picture as an example to give you a better understanding for the resolution of images. But something about monitors first. I use a graphic monitor with 1024 x 1280 pixel (dots). The size is 270 x 337 mm (a 17 inch monitor). This correspondends to 38 dots per cm (dpc) or 96 dots per inch (dpi). The picture 16 FP has a size of 912 x 360 pixel and measures on my monitor 24 x 9,5 cm. There are of course a lot more resolution combinations, but the LCD 1024 x 1280 pixel monitor (generated by the graphic controller) is wide-spread. I take the data of my monitor for the following examples.
To show the full resolution of picture 04 FP (19.162 x 48.565 pixel) on my monitor, the image size is 5,04 x 12,78 meter (!). That is the size (100%) I have to handle for retouching. Picture 1 shows the resolution as I see the picture during this final work on my monitor. The picture 2 shows the detail-resolution as you will find it with all of my pictures in my works. But now some examples for the print resolution of my pictures. For printing I use the Epson Stylus Pro 9600 with seven separate Epson UltraChrome inks (for museums quality) and a maximal print space of 111,8 cm (44 inch). This print space limitates my own outputs as shown in List of work numbers. I have done full size prints as well by composing up to three prints onto one 4mm Alu-Dibond support (Picture 4). I print on Premium Glossy Photo Paper (250 gr). grieger-online.de for example is able to do art prints in museums quality in one piece up to a print space of 180 cm. If you want to achieve a good print quality in detail as well you need a picture resolution of 300 dpi at least. All my large format pictures of this galleries have this resolution and on the main page of every picture you will find the biggest possible output in the named resolution (click top picture). The output resolution I use on my Pro 9600 is 720 dpi. Output-dpi should be even or better than input-dpi. The Picture 3 shows a clipping out of motive 04 FP as 162 x 411 cm-version with 300dpi. So far the technical side. I have written this only for a better understanding of the process. If somebody wants to know more, I can recommend the sites of Max Lions and Brain Caldwell. And now please have a more detailed look to my series. |
