Taking Clear Pictures With a Cheap Camera (Saque Fotos Claras Con Una Cámara Barata)





Introduction: Taking Clear Pictures With a Cheap Camera (Saque Fotos Claras Con Una Cámara Barata)

The pictures of instructables that try to show near details are generally... deplorable. Unnecessarily .

(Las fotos de Instructables que intentan mostrar detalles cercanos son generalmente... deplorables. Innecesariamente)

Step 1: A Couple of Cheap Reading Glasses (that Are Sold in the Street) Can Solve the Problem.

(Un par de anteojos baratos de los que se venden en la calle, puede resolver el problema)

Prefixing a lens of 2 dioptries to a fixed focus camera, pictures are obtained with good definition to 46 cm distance. Two lenses of 2 dioptries makes 4 dioptries, and the distance decreases to 23 cm.

(Anteponiendo una lente de 2 diotrías a una cámara de foco fijo, se pueden obtener fotos con buena definición a 46 cm de distancia. Dos lentes de 2 dioptrías hacen 4 dioptrías, y la distancia se acorta a 23 cm).

Prefixing a lens of 4 dioptries, pictures are obtained with good definition to 23 cm distance. Two lenses of 4 dioptries makes 8 dioptries, and the distance decreases to 11.5 cm.

(Anteponiendo una lente de 4 diotrías, se pueden obtener fotos con buena definición a 23 cm de distancia. Dos lentes de 4 dioptrías hacen 8 dioptrías, y la distancia se acorta a 11.5 cm).

In fact any lens serves, making try and error. I stuck to the mount of each lens an appropriate thread of the exact focus length, for not having to take the measure with a rule every time.

(En efecto, cualquier lente sirve, haciendo prueba y error. Yo pegué a la montura de cada lente un piolín de longitud igual a la distancia focal, para no tener que medir la distancia con una regla cada vez).

I attached two pictures (before and after, with 4 dioptries)

(Puse dos fotos, antes y después, con 4 dioptrías)

1 Pic = 1000 words;
2 Pic+ 125 words = 2125 words.

(Una imagen vale más que mil palabras; una imagen más 125 palabras, valen más que 1125 palabras)

The principle is very simple. The measure in dioptries is the inverse of the focal distance in meters. Therefore, a lens of 2 dioptries has 50 cm of focal distance. A lens of 4 dioptries has 25 cm of focal distance.

(El principio es muy simple. La medida en dioptrías es la inversa de la distancia focal en metros. Por lo tanto, una lente de 2 dioptrías tiene una distancia focal de 50 cm. Una lente de 4 dioptrías tiene una distancia focal de 25 cm).

As the cam is not focused to the infinite but to about two meters, those 50 cm decreases approximately to about 46 cm. It Depends on the camera.
(Como la cámara no está enfocada al infinito sino a una distancia aproximada de 2 m, esos 50 cm se convierten en 46 cm. Eso depende de la cámara).

The focal distance (and consequently the dioptries) of a lens is obtained easily at the sun. One must form the most concentrated focus that one can obtain (the one that is used to burn ants), and the focal distance is between the bright point and the lens.

(La distancia focal -y consecuentemente las dioptrías- de una lente se puede obtener fácilmente al sol. Uno debe formar el foco más concentrado posible (el que se usa para quemar hormigas), y la distancia focal es la que hay entre ese punto brillante y la lente).

The cheaps reading lenses are'nt glass, they are some type of organic plastic. Then, is relatively easy forms it with a bench grinder. Previously it is necessary to stick a packing tape on both faces of the lens to avoid to scratch the surface. When the lens has the wanted diameter, mount it inside a tube over the camera's objective. I made the tubes (one for each lens) with can of soda. It is very easy to work it with a common scissor.

(Las lentes de lectura baratas no son de vidrio, son de algún tipo de plástico orgánico. Por lo tanto, es relativamente fácil darles forma con una amoladora de banco. Previamente es necesario pegar una cinta de embalaje en ambas caras de la lente, para evitar rayar la superficie.  Cuando la lente tiene el diámetro deseado, se monta dentro de un tubo ante el objetivo de la cámara. Yo hice los tubos -uno para cada lente- con lata de gaseosa. Es muy fácil de trabajar, con una tijera común).

    I think part of the confusion here is that you might want to say that you are talking about taking focused photos of close up things. I wish you would change your intro image to the focused one. If you added a few more shots of small things I think the process and what you are teaching would become clearer. You are the one of  the most patient and polite people on this site. 

    Change your title to reflect that you are talking about close up shots.

    Your observations are correct, now that you mention it I realize. Unfortunately the camera I used to make this instructable does not work, and would be unethical to put a photo taken with a camera of better quality.

    I swop the photos, and translated to castilian the texts.
    I hope that is better.

    Thanks for all.

     your picture is quite blurry.
    a better way to do this is BUY A TRIPOD

    Bear in mind I'm talking about a cheap camera, and in 2006. The purpose of instruction is not to teach to get good photos, but photos fairly acceptable for a instructable.

    id be funny if you have an instructable that shows you how to take clear pictures while you only have blurry ones

    Thanks, you're very kind and considerate.

    what do you mean?

    Your English was fine. My question is where can I get the type of lens you're describing? And if it's a cheap camera, how would I attach them?

    If you live in U.S.A, you may be able to get the glasses at a pharmacy like CVS or Wallgreens.
