He did recall how long the procedure took: two months, "and even then it wasn't totally obliterated," he added. "I went through a lot of erasers." There was no fanfare when it debuted at New York's Elinor Poindexter Gallery. It was just another part of the show. But in fact, this was a major event for an artist who had until then focused exclusively on painting.
The image was a rough sketch of a man's face, done in pencil on cartridge paper. Rauschenberg had bought eight boxes of this kind of paper at a stationery store and found that by rubbing it with pumice stone and sandpaper, you could get rid of most pencil marks. This allowed him to start over fresh without contaminating the original.
Rauschenberg also recalled that during this time he lived alone in a small apartment on East Tenth Street in Manhattan, which didn't help ease the tension caused by his demanding work schedule. He said people would come to his door unannounced to check out what he was up to art-wise since they knew nothing about him otherwise.
But despite all this anxiety, chaos, and uncertainty, something wonderful happened between 1959 and 1961 when nobody was watching. Rauschenberg invented a new way of making art that has inspired many painters and photographers ever since. The method he came up with? He simply started over again!
Erasable pens employ a liquid rubber cement solution that is put on top of the paper, as opposed to traditional pens, which use inks created from oils and dyes that stain paper. Erasable "ink" is indistinguishable from conventional ink in appearance, but it can only be removed neatly for around 10 hours. After that, it will start to smear.
The life expectancy of an eraser pen depends on how much you use it. If you go over your notes regularly, then they will need replacing sooner rather than later to keep them clean. Generally, though, they should last for several years if you don't erase too heavily or over-wipe your page. If you do any kind of work that uses oil-based paints or markers, however, then these items will need replacing more frequently. They are not designed to be used with water based inks such as those found in laser printers.
There are different types of eraser pens on the market today. Some work on electricity while others use mechanical pencil lead. There are also refillable versions available that replace the ink cartridge with one that holds the eraser material. Finally, there are disposable pens where both the tip and body are made out of plastic and can be thrown away after one use.
Whether you're using a traditional fountain pen or an eraser pen, keeping your spacecraft clean is important for extending its life span.
James Berridge spent over 100 hours masterfully fixing and coloring 26 antique black and white images of every US President who lived before color photography was invented. Each presidential portrait required around 5 hours to colorize, with the longest requiring up to 9 hours.
Berridge began the process by scanning each image into his computer. From there he used Photoshop and other software to fix any problems with the picture such as clouds in the background, scratches on the photo, etc. After fixing the original photograph, Berridge then colored it using traditional watercolors. Once all the colors were applied, he finished the portrait by adding details like buttons and stitching lines together various parts of the image.
Berridge has posted photos of each stage of the process on his blog: www.jamesberridge.com/blog/. He says that making political portraits is more difficult than making historical ones because you need to make sure that your colors don't look garish when combined with modern politics.
Presidential portraits date back to the early days of the Republic. The first one ever taken was done in 1793 by Thomas Jefferson as a gift for the people of France. Since then, almost every president has had their own portrait taken once they have been elected to office.
The best solution is now being voted on. It took four years to complete (1503–1507). Despite the fact that it was incomplete, it took another three years to complete, up to the painter's death in 1519.
The painting itself is about 30 inches by 24 inches (76 cm by 61 cm), on a panel of wood painted black. The hair and eyes are brown, the skin dark olive green. He is wearing a red cap, with a white feather in it. He has a yellow jacket with blue sleeves and buttons, lined with red. Over this he wears a purple cloak with a red trim. He also wears brown breeches, with stockings and shoes. His hands are bare of paint but his tools are still lying next to him on the floor.
So, it took about eight hours to paint the face, then another four hours for the clothes and accessories. The entire picture therefore took about 12 hours to complete.
However, this does not include the time it took to choose your colors. If you look at other paintings by Leonardo, such as "Madonna with Child" or "St. John the Baptist", they often have very specific colors on them. So I would say that it takes about two days to fully decide on your colors before you even start painting.
Stretch and knead it, or cut it into pieces and assemble them. Continue until it turns gray and all of the black markings are blended in. These erasers are more durable than others and may be used for years. You may notice that it leaves filthy streaks on the paper rather than erasing. This means that it has become obsolete and should be discarded instead.
The best way to ensure that you get the most out of your kneaded eraser is by cutting it up into pieces first. This makes removing individual letters much easier. Once you have erased a section of your paper, you can throw it away and start again with another piece of paper.
Kneaded erasers come in two shapes: cubes and disks. Cubes are perfect for erasing small areas while disks are better for larger sections of paper. They both work by applying pressure to the paper with embedded rubber particles. As you press down on the eraser, these particles compress, causing them to mold to the surface you are trying to erase.
Because kneaded erasers are made of rubber, they will eventually break down over time. That's why it is important to use them only on paper surfaces, not on wood or metal. The particles within the eraser may end up embedding themselves in these materials instead which would render it useless.
