Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.

The Warnerke Standard Sensitometer consisted of a frame holding an opaque screen with an array of typically 25 numbered, gradually pigmented squares brought into contact with the photographic plate during a timed test exposure under a phosphorescent tablet excited before by the light of a burning Magnesium ribbon. The speed of the emulsion was then expressed in 'degrees' Warnerke (sometimes seen as Warn. or W.) corresponding with the last number visible on the exposed plate after development and fixation. Each number represented an increase of 1/3 in speed, typical plate speeds were between 10 and 25 Warnerke at the time. What are the answers to this following set of questions: 1.

I am Steve. I was born and grew up in South Wales. My favorite place to play was out on the hills where my imagination had plenty of space to expand . My family moved out of Wales when I was thirteen. I went to a new school. One of my subjects was French. Because I had never learned any French, my teacher told me to sit in the corner and write anything I was interested in. That's the time I started writing, just for myself, and I've been writing ever since. I have always loved BIG IDEAS, and so I enjoy writing fantastic stories. And I also write horror I think they are like the old fairytales ,and can teach you important things. I am in my forties on the outside, twelve on the inside. I like rock music, Indian and Chinese food, and I enjoy drinking. I live in a small village with my wife Mary, ducks, cats, goats, hens and lots of rabbits.

Dr.Michael Prager, a leading Botox expert, said that a growing number of women are developing something called "computer face".He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls , "turkey neck" and deep-set wrinkles on their forehead and around their eyes.

The Botox expert said that, of all his clients, office workers were most likely to show premature signs of ageing."If you are one of the unfortunate people who frown while you are concentrating on the screen then, over time, you will inevitably end up with frown lines," Dr.Prager said."What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long.If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck."

Dr.Prager, who has a practice near Harley Street in London, said he encourages his clients to put a mirror next to their computer so they can see if they are frowning at the screen."When people are stressed or thinking hard about something, then they will often put on a 'grumpy face' without even knowing what they are doing.When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them."

He said, "The women I am seeing at the moment have only been using computers at work for the last decade or so.But women in their 20s have grown up with them and use them for every single task.I think the problem is going to become much, much worse.In another ten years, they could be looking quite awful."

Dr.Prager said there were several simple steps which could avoid "computer face" such as regular screen breaks and stretching the neck muscles.And, of course, there was always Botox.He said that, after a couple of sessions of Botox, the habit of "grumpy face" could be broken. What are the answers to this following set of questions: 1. Who is most likely to show premature signs of aging?
2. Why are they likely to look that way?
3. Will the problem get worse in the future?
4. What is this problem being called?
5. Who is the professional talking about this?
6. Is there a method suggested for avoiding this?
7. Is there any other method available?
