Nothing is better than reading a good book, especially when there isn't the need to do anything else but plug in the Amazon Kindle for sale. This device is one that I have found to bring hours of reading pleasure, without having to turn the pages of different books. Through the Amazon Kindle is the ability to enjoy the classics of books, as well as the newer options that provide a wealth of knowledge and enjoyment.


What To Read Into?


The Amazon Kindle for sale is a completely new and unique device, that takes all the trouble out of reading. It is a hand held device that is available with the concept of the electronic paper. This means that books, newspapers, blogs and other online writing is all available with the push of a button. This isn't the only great thing about the Amazon Kindle, however. It also carries Whispernet, which is like Wi-fi, but better. It is able to generate the online text, even when there aren't any hotspots, allowing you to connect and to stay connected, even if you are in the middle of Kansas or on a flight over the Atlantic Ocean.


Is It Really an Electronic Revolution?


To begin, the Amazon Kindle for sale is able to offer over 230,000 titles to read. Just in case you thought you would run out of titles, you don't have to worry anymore. This includes the ability to hold 7 times more storage that its previous version, over 1,500 titles at one time. Not only this, you also have the option of transferring Mp3s and music into the same portal, so you can listen to your favorites while you are reading.

Is Your "Old" Book Valuable?

Some old books are valuable, some are just old! How do you tell? There are several factors which determine if a book is worth money to a collector. Here are some tips to guide you:


Age does not make a book valuable. At least , not age alone. Some books can be a hundred years old and not bring much, others need only be a few decades old to bring a nice return. The importance of what the book relates, it's physical condition, and demand also count for much. In general, when it comes to age, look for books printed before 1501, English books printed before 1641, books printed in the Americas before 1801, and books printed west of the Mississippi before 1850.


Condition is key! A book's physical appearance and its completeness make a huge difference. Is the binding tight? The cover intact? Pages clear? All these things a more will help determine value when rating a books condition. In general, the better a book's physical condition, the more it will be worth. A rating of "fine" is given to a book which is complete and shows very little or no wear. Loose pages or a worn cover will place a book in "poor" condition. There are "good" and "fair" ratings in between. Completeness, however, is KEY - missing pages or illustrations will make most books almost valueless.


Dust Jackets are vital. Virtually all books from the late 19th to today had one. And having it, in good condition, greatly increases the value of the book. As an example, if one searched records at Alibris for first editions of Harper Lee's To Kill a Mockingbird, you would find a "good" first edition/first printing for $6,500... without a dust jacket. For a copy in the same condition and printing, with a "good" dust jacket?  The price sky rockets to $30,000! The major exceptions to whether a book had a dust jacket are the specially bound books, often limited editions. If a book is bound in real leather, there's a good chance it was not issued with a dust jacket, although it might have been issued with a slipcase, which is also important to the value of the book and should also be in good condition!


The contents of a book are also important. What is the books contribution? A major contribution was made to human understanding the first time Darwin's work was published. Jane Austin's books, they way her contemporaries found them, entice collectors today. First editions of these books would fall into this category. Apart from the first time the work was published, major changes to the work which significantly add to the contents can also make a book sought after. Illustrated editions, especially those by prominent artists, or titles with introductions by eminent contemporaries would be examples. Books that were banned or censored may be valuable because of their contents or even rarity, since few copies may have survived. Special binding or an innovative printing processes can make a huge difference. In general, markings, and inscriptions will be a problem and lessen the value of a book but there are exceptions; an autograph, inscription, or marginal annotations of a famous person can contribute to a book's importance and raise the value.


Rarity is a factor. As mentioned above, banned or censored books and books produced during certain periods or in particular places may mean that there are few available to collectors. As with other times, supply and demand is king! One can search the Internet on sites such as Bookfinder.com, AbeBooks.com, EBay, or ABAA.org to get an idea of how many copies of a book are being offered for sale. Auction sites can tell you how they are selling. Many booksellers have searchable catalogs and databases on their websites and these can be helpful in determining an approximate market value. Because the details can determine worth, pay close attention to the descriptions you find and make as close a match as possible. But remember, even if rare, if the condition or contents are negligible, it is likely to have little monetary value.


First Editions, when it comes to contemporary works especially, are important. The first time a book is published using the same setting of type (be it metal type, prototype, or camera-ready copy), is an edition. It may be an edition of 10,000 copies or 100,000 or more. If a book is popular, it may be reprinted over and over, with minimal changes, until demand is satisfied. This is a "printing". It is the First Edition, or the first set of books to "come off the press" which are the most sought. Information about editions and printings is usually included on the title page of a book or on the back (verso) of the title page. Without this information, the edition or printing is hard to determine and usually requires research. Collecting of true "first editions" of contemporary works has grown and raised the value of titles which are not especially old substantially. Writer's like Stephen King, Kurt Vonnegut, and JK Rowling find their first editions rising in value.


In some cases, even book club editions of titles can be collectible and of interest. For some authors and some editions, book clubs are preferable to paperback originals. For example, Danniel Steel fans like to collect the hard covers of her books, but the early ones were only available in paperback. If these are found, they're usually in pretty bad shape. For this reason the book clubs, which ordinarily go for from $2 to $5, may command prices from $8 to $15 and even a bit higher if signed. Some collectors insist on a copy of every edition, including BCEs, paperbacks, etc. Books from certain book clubs are also collectible. The Folio Book Society publications will always be collected. Collin's Crime Club (which was a different sort of Book Club) will always be collectable as long as people want to buy Agatha Christie firsts. In general, hwever, the book clubs do NOT command that much of a price (about equivalent to collectable paper backs).


A "limited edition" can be valuable, depending on the book and how limited it is. Again, rarity can come into play. The term is reserved for editions where copies have an explicit "limitation statement" which contains information on the number of copies printed, and usually a breakdown of how many copies were printed on a certain type of paper, or bound in a certain kind of binding, or reserved or withheld from sale. The statement is usually found on the back of the title page or on a separate page at the beginning or end of the volume. The number of the specific copy is often printed or added by hand (as in "no. 46 of 500"). The lower the number of the copy, the more valuable. If accompanied by the autograph of the author(s), publisher, or other contributor, so much the better! Whether looking at first or limited editions, the size of an edition does not by itself determine a book's value, or even its rarity. Other factors play a part.


Provenance or ownership can improve a book's value, if that person is important or famous and if the book held significance for him or her. Autographs, inscriptions or dedications, bookplates or stamps, or other distinctive markings can be proof of ownership, but they can also be forged. Authentication is important.


To promote sales and for charity, contemporary authors routinely sign copies of their books. Because these are common, modern autographs usually add little value. However, "presentation" or "association" copies, those signed on special occasions, or inscribe and presented to important associates and friends may greatly increase the value of a title. "May" is the key word here - expertise in the current market is needed to make a valuation of this.


So, do you have old books? Or valuable books? The book collecting market is like any other collectible market, constantly changing. Authors go in and out of favor; time periods and type styles became popular and then fade. You need to remember that books, as with any other collectible, are only worth what someone is willing to pay for them. Doing a little research and being honest to yourself about your items will save you space, time, and maybe make you some money!

Leonardo's Da Vinci's Water Study

About 500 years ago, Leonardo Da Vinci (1452-1519) recorded ideas about vortices based on his experiments with water. In fact, the subject of water, hydrology, and hydraulics made up a large part of Leonardo's lifetime study. As a matter of historic note - more of Da Vinci's writings were devoted to the subject of water than any other subject. The existence of water and its vortices intrigued Da Vinci, prompting him to speculate about the existence and behavior of vortices in the air and cosmos. The power and meaning of vortices in water also led him to closely study the behavior of water under different conditions.


Da Vinci's fascination with fluid dynamics and vortices crossed over into his art - with the flowing motions of water and vortices being expressed in his paintings and sculptures.


The existence and behavior of bubbles in water was also of interest to Da Vinci, since he noted from close observation that bubbles rise through water in a spiral motion. In his written notes in the Codex Leicester Folio 23V (now owned by Bill Gates), he observed that the "motions of waters always move in a circle from surface to bottom."


Da Vinci spent many years in his makeshift laboratory and in the field observing the movements of water and air. To see the fluid dynamics of water at work, he did experiments using glass tanks so he could watch the motion of flowing water under various scenarios. During his field research, he maintained detailed notes and drawings to record his experiences and observations.


To facilitate his research, he invented a water gate that utilized the pressure of water to create a tight seal. Unforseen by DaVinci at the time - his experiments and detailed technical drawings of this water gate would survive through time and eventually be used in designing the lock gate system of the Panama Canal.


At times, Da Vinci's mind would ponder the many realms of water as his observations often triggered writing ideas. As a habit, he would jot down or sketch these thoughts along the margins of his papers while working on other subjects. One such series of notes in the upper right hand corner of one of his papers provides us with his outline for a proposed treatise on water. It was divided into fifteen books, with each book dealing with a different aspect of water:


1. Of Water in Itself


2. Of the Sea


3. Of the Veins


4. Of Rivers


5. Of the Nature of Bottoms


6. Of Objects


7. Of Various Kinds of Gravel


8. Of the Surface of Water


9. Of Things Moving in It


10. Of River Repairs


11. Of Conduits


12. Of Canals


13. Of Machines Turned by Water


14. Of Raising Water


15. Of Things Worn Away by Water


Given the numerous other activities Leonardo was involved in, he never found the time to complete this series of water books. His writings, especially the Codex Leicester, contain many references and brief notes to be included in these books. An example of this can be found in his notes dealing with precipitation: "Write how clouds are formed and how they dissolve, and what it is that causes vapour to rise from the water of the earth into the air, and the cause of mists and of the air becoming thickened, and why it appears more blue or less blue at one time than another. Write in the same way of the regions of the air and the cause of snow and hail, and how water contracts and becomes hard in the form of ice, and of the new shapes that the snow forms in the air."


Another of Da Vinci's field observations explored the physical expression of the vortex principle on a grand scale. His written observations about a water spout he saw along the seashore were recorded on a page entitled "Of wind twists and eddies involving water." As expressed in Da Vinci's inimitable words:

It often happens that, when one wind meets another at an obtuse angle, these two winds circle around together and twine themselves into the shape of a huge column, and becoming thus condensed, the air acquires weight. I once saw such winds, raging around together, produce a hollow in the sand of the seashore as deep as the height of a man, removing from it stones of considerable size, and carrying sand and seaweed though the air for the space of a mile and dropping them in the water, whirling them around and transforming them into a dense column, which formed dark thick clouds as its upper extremity.


Many people will probably never see such a waterspout land on shore in their lifetime, but thanks to Da Vinci and his detailed notes from long ago, we have the opportunity to appreciate the feeling of such an experience.

Learn Photoshop Sharpening Techniques

Sharpening in Photoshop enables you to select the precise amount of sharpening and the areas of the image that require sharpening most. The actual amount of sharpening required for optimum image quality is usually a little more than looks comfortable on screen even if you are using a TFT monitor.


With the help of Photoshop Techniques, we will learn about sharpening the eyes of a portrait excluding the skin texture.


The best sharpening techniques are those that give priority to the important areas for sharpening and leave the smoother areas of the image well alone. Hence let the project begins.


It is important to switch sharpening options (if any) off or set them to minimum or low in your capture device. Most of the capture devices have the sharpening features that are often very crude when compared to the following technique.


You do not need to sharpen images that have been saved as JPEG files using high compression/low quality settings. The sharpening process that follow must also come at the end of the editing process, i.e. adjust the color and tone of the image before starting this advanced sharpening technique. Decrease the levels of sharpening later if it proves too much.


First Technique: High Pass


1. Copy the background layer and set the blend mode to Overlay. Select 'Overlay' from the blend modes menu in the layers palette.


2. Go to Filter >> Other >> High Pass. Raise the pixel radius until you achieve the correct amount of sharpening. Set pixel radius of 1.0 if printing to Gloss paper and 3.0 if printing to Matte paper.


3. Choose the Foreground color swatch in the Tools palette for opening the Color Picker. Enter 0 in the Hue and Saturation fields and 50% in the Brightness field to choose a midtone grey. Select OK. Paint the High Pass layer to remove any sharpening that is not required, like skin tones, skies etc, as High Pass technique is useful for limiting the visual appearance of noise or film grain.


4. Remember the settings you have selected are being viewed on a monitor as a preview of the actual print. In order to complete the process it is important to print the image and then fix on whether the image could stand additional sharpening or whether the amount used was excessive. If the settings are extreme, choose to lower the opacity of the 'High Pass' layer. Then again switch the blend mode of the 'High Pass' layer to 'Soft Light' to reduce the sharpness or 'Hard Light' to increase the sharpness.


Saturation and sharpening


Most techniques to increase the contrast of an image will also have an unforeseen effect of increasing color saturation. Since the High Pass and Unsharp Mask filters both raise local contrast there is an extended technique if this increased color saturation becomes tricky. Be aware of color fringing after you apply the High Pass technique. Do consider the following technique to limit its effects.


Second Technique: Unsharp mask/Smart Sharpen


The second technique address the issues of increased saturation leading to the effect of color fringing. If a merged layer is used as the sharpening layer and then changed to Luminosity blend mode the effects of saturation are removed from the contrast equation. This technique looks how the benefits of localized sharpening and Luminosity sharpening can be combined.


1. Adjust the Blend mode of the High Pass layer back to Normal mode. After that, apply a Threshold adjustment to the High Pass layer. Select Image > Adjustments > Threshold.


2. Pull the slider just below the histogram to isolate the edges that require sharpening, in order to render all of those areas you do not want to sharpen white. Click 'OK' when you are done. Paint out any areas that were not rendered white by the Threshold adjustment that you do not what to be sharpened.


3. Choose the Channels palette, either Ctrl-click (Windows) or Command-click (Mac OS) the RGB thumbnail or click on the 'Load channel as selection' icon from the base of the channels palette to fill the edge detail as a selection. Go back to the layers palette and pull the Background layer to the new layer icon to make a background copy layer. Pull this background copy layer to the top of the layers stack.


4. Turn off the visibility of the High Pass layer. Press down the Alt or Option key and click on the 'Add layer mask' icon in the layers palette. Make sure that the layer mask thumbnail is the active part of the layer and then choose Filter > Blur > Gaussian Blur. Set 1.5-pixel radius blue to the mask.


5. Click on the image thumbnail on the background copy layer. Make sure the image is zoom in to 100% for a small image or 50% for a larger print resolution image (200ppi - 300ppi). Select Filter > Sharpen > Smart Sharpen or Unsharp Mask. Adjust the Amount slider between 80-150% to control that how much darker or lighter the pixels at the edges are rendered. Prefer an amount slightly more than looks comfortable on screen if the image is destined for print rather than screen.


It is recommended to see Capture and Enhance for basic settings of the Unsharp Mask filter. The accurate Threshold and Radius settings are not so critical for this advanced technique.


6. Transform the blend mode of the sharpening layer (the uppermost layer) to Luminosity mode so that it will restrict the contrast changes to brightness only, and will eliminate any changes in saturation that have occurred due to the use of the Unsharp Mask. Use this technique only when you are aware about problems of color fringing due to increased saturation.


See yourself the effects of changing the blend to Luminosity. These two techniques are capable of producing razor sharp images that will really put the final changes to a folio quality image.
