Portia in Shakespeares The Merchant of Venice and...

Portia in Shakespeares The Merchant of Venice and Abigail of Marlowes the Jew of Malta Portia and Abigail are two characters with very different values. Portia in Shakespeare’s The Merchant of Venice remained true to her religion, and her father’s wishes throughout the play. Abigail, on the other hand, changed religions and disobeyed her father. However, the writers used these two women to make similar statements about religion. Portia represented the quintessential Christian. Abigail of Marlowe’s The Jew of Malta, was more of an ethically ambiguous character, but it can still be argued that she was the most principled character in the play. Both Shakespeare and Marlowe used the daughter character to represent the ideal human†¦show more content†¦Already Portia clearly puts her sense of duty ahead of her desires, as a good Christian should. Later, in the trial scene, Portia again showed her love of the law, but attempted to use the law with mercy. She gave Shylock a choice as she judged the trial. She said he may choose either to be merciful to Antonio or the court would abide by the law- word for word. Shylock did not accept her offer because he felt that he was entitled to the justice of the law. Portia would never have broken the law, but she was able to find a way to use it to her advantage. â€Å"This bond doth give thee here no jot of blood; The words expressly are ‘a pound of flesh,’† (Merchant of Venice, IV.i.306-307). Portia found the loophole in the bond that none of the other characters could see. It was a triumphant moment for her because she was able to release Antonio from his debt while still being utterly just and fair. â€Å"He shall have justice and his bond,† she explained to the court (Merchant of Venice, IV.i.339). She is was the same time more lenient and s tricter to the letter of the law than Shylock and defeated him on his own terms as well as by Christian terms. When she offered Shylock a chance to be merciful before she used the full extent of the law against him, Shakespeare’s audience would have seen that as evidence ofShow MoreRelated Father-Daughter Relationships in Sidney’s The Countess of Pembroke’s Arcadia, Marlowe’s The Jew of Malta, and Shakespeare’s The Merchant of Venice3187 Words   |  13 PagesFather-Daughter Relationships in Sidney’s The Countess of Pembroke’s Arcadia, Marlowe’s The Jew of Malta, and Shakespeare’s The Merchant of Venice Justification for the subjugation of females to males during the sixteenth century came from a variety of sources. Ranging from the view that God gave Adam authority over Eve as penalty for the fall, to a belief in the superiority of a husbands’ physical strength over that of his wife, attempts at rationalization of the restricted freedom of women

SLR digital camera Essay Example For Students

SLR digital camera Essay On a SLR digital camera it should have a dial that turns the camera on manual, the M setting is when the photographer have complete control unless the camera has preset limitations that doesnt allow it to do certain things. In the M setting it should allow the user to change the shutter speed and the aperture, when taking a picture that one needs to stop all action or time in the picture, it should be shot at a speed of 125 and greater, depending on your subject, to give water its moving effect you would need to shoot the photo of 60 and less to create the effect, while changing these setting you will have to compensate the other settings such as aperture, aperture is the opening of the camera, which controls the amount of light the passes the shutter, by increasing the size more light will come into the camera, having the film more exposed. The aperture is measured by f-stops the higher the f-stops the smaller the opening in which the light goes in, for example f-stop 2. 8 is bigger than 3. 2, the f-stop not only adjust the light coming through, but also the focal point of the image, and helps create a sense of depth in the photo. When taking a picture with depth one wants to see how far you are from the subject the closer the person the wider the aperture, hence a lower f-stop, when you take a picture of a subject far away one you should have a higher f-stop, a smaller aperture/opening. By doing this it will help focus the picture to a certain point, or to focus as much as possible in the scene, to make a sharper image, so that the focusing in the lens can produce a photo with more depth, because it shortens/lengthen the focal area. In most cameras there is a presetting that is called depth of view mode, what that does is that it will chose the best setting to take a picture where everything is in focus. Also in the mode dial, there should be a setting called Av, which is aperture priority, the camera will then adjust its setting around what the user set for the aperture, and how exposed the picture will be, this setting allows the photographer take a picture with the desired f-stop, without having the photographer adjust the shutter for a proper exposure. There is also another setting called Tv, which is shutter priority, where the camera sets its own setting according to the shutter speed that the, user had set, this allows the user to set the desired shutter speed for different effects, while lightening the load of information the user has to take in. In many cameras the setting may have different names because this essay is based on a Canon camera. For most SLR cameras the lenses normal cost way more than the lens, because normal the camera breaks down faster than a normal lenses. So if one decides to replace your old SLR oneyou shwouldd like to find a camera that is compatible with the lenses one already owns. When walking in to a camera shop it is better to walk in blind, ask a lot of questions, and let the salesman show you around, this will see if they know their stuff, did I mention ask a lot of questions? So how does one pick a good lens? In a normal 35mm film format, a 50mm lens would be the equivalent of what your eyes sees and is a 1:1 conversion, but on most digital SLR because of prices, and quality most of the digital SLR have a film conversion of 1. 3x/1. 6x and making a lower mm lens to be more telephoto than it would be than in a normal camera. When looking for a good camera lens one should first look at what kind of connection the camera uses to attach on to theiryour camera, hopefully they are compatible first, and then look for what effects or shots that theyyou want to take. There is no point in doing a portrait shot with a macro or wide angle lens, there are many different kinds of lenses they are ultra wide-angle zoom, standard zoom, telephoto, telephoto zoom, macro, tilt-angle lens, super telephoto etc. Next see if the optics of the lens match the cost and also what you want to be doing with the lens, a 28-70mm lens could have more desirable things than another lens but one might lack. A couple features, such as a special lens coating, or floating aspherical lenses,that one might so you want to see if the lens meets what your expectation, there is nothing worse than getting ripped off of the price. Then of course what should also be a concern is the maximum f-stop of the lens that oneyou would like to get. Reading an Advert EssayIn the golden mean is similar to the rule of third but instead of splitting the photo in to nine equal sections it divides it into it first splits it into nine unequal sections then splitting it with four lines, to use the golden mean is like to use the rule of thirds placing objects of importance in the intersecting areas the 4 secondary lines are used to align other lines to it, such as the line of a street. When taking a photo it is also useful to observe the textures in the photo to create an interesting photo, textures can greatly create depth of a photo. A good example of a good texture is a split piece wood, if shot in at an angle can give good results. The best way of utilizing textures is in black and white photography, because of instead of having colour that emphasizes the saturation or that hues, which can be distracting, black and white emphasizes the textures. In most pictures complexity can be overwhelming, if used in a wrong way, because there might be things in the photo, which could distracts the viewer from the main point of the picture, especially if the picture has more than one subject of interest. Complexity can work both ways, it allows the viewer to be mesmerized instead of just letting a viewer skim past the photo, and a good example of this is machinery where there are a lot of gears. The thing that occurs in photo, which are complex, and not too distracting, all have the trait that the picture has components, which are mutually the same. Simplicity is very important in a picture because it allows the picture to convey the message much more effectively because of the lack in distractions. In simplicity it is best to leave things by them selves instead of bring the whole scene in your picture, say if there is a chapel, and there is also a parking lot, with a telephone booth, it is better to just take a picture of the chapel, and leave the other component for other pictures. The depth of a picture is important to a picture because it adds dimension to a photo instead of having the photo look 2D. You can create depth in many ways having a large aperture that would narrow the amount of the picture that will be focused, by manipulating the things in focus, it will make a more 3D look in the picture. By having a foreground, a midground, and a background, it will make a picture with more depth than just having one or leaving out one of these categories. Lines are just lines until you actually bend them and move them a straight and vertical line is too plain and too normal, but if you bend them, then the sky is the limit. A S curve is pleasant to the eye and combining a S curve with it starting from one side and leading away from the picture, is quite a combination. Usually curved lines are much preferred than straight lines, and having lines leading off to the side is also a good thing to have. Shapes are just lines which are closed, to form a shape. The rule of the lines also applies to shapes, lines that have curves, is better than straight lines. Shapes can be more constructive than lines because of the shapes have more than one way of looking at it. In the modern age of digital cameras, the skill involved in taking a good picture has decreased. But I hope that this essay might have given you an insight to the expansive world of photography. There is a growing number of people that is starting to use a S.L. R. camera because the age of digital camera, letting people take photo without having consequences which was involved in film such as developing and the cost of buying film and developing. This essay was meant to teach you about a camera and how to become a better photographer, but not to go out and buy a new camera, the camera you have now should beis sufficient, its much better to spend more time, and money with your family, a camera is only a camera, its who that takes the picture that counts.
