Zoom lens

Zoom Lens definition:

A lens allowing a camera to change smoothly from a long shot to a close-up or vice versa by varying the focal length.

Most entry level digital SLR cameras are supplied with a zoom lens allowing the user to switch from wide angle shots through to telephoto.   Zoom lens’ are highly flexible, however certain photographers will purchase specific lens for dedicated purposes.

Focal Length

The most important factor in any camera lens is its focal length. This determines which type of lens it is, and what subjects it will be able to photograph. Focal lengths range from just a few millimetres up to over a metre, and can be loosely grouped as follows:

Lens focal lengths, types, and uses

Wid eangle lenes (short focal length) capture more because they have a wider picture angle.

Telephoto Lens (long focal length) have a narrower picture angle.

A longer focal length is associated

Technique-Macro

Macro

Definition 

A macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater, although most of the time we will end up looking at a large size image of a really small insect or flower, for example.

Best Images

I like how detailed this images however the lighting could be better. Although not in frame correctly I like how the image is not perfect.


This image shows the whole eye unlike the top one. The colour of the iris in this image is brighter.


This image has little negative space, which is good for a macro image.

Images that require improvement

The background is not clear as the top left corner has someones finger in it. I also think that the image    could have zoomed in more.

 
I stem is unclear. I think the steam of the flower should be as clear as the rest of the flower

Techniques- Sequnces

Techniques

Sequnces

Definition- By definition, a sequence is a serial arrangement in which things follow in logical order or a recurrent pattern. Photo sequencing is actually stitching multiple images together and it is a form of time-lapse photography. A change in an object’s position over time is being displayed and it only works when the object moves across a static background.

Settings:

Manual Exposure 

Shutter speed: 1/80

F stop: 5.6

ISO: 200

How can I achieve a photo-sequence.

1.Tripod

2.Fast shutter speed

3.Manual camera settings (to fix the exposure)

4.Manual focus

5.No Camera shake (be careful when pressing the button).

6.Direct the shoot (composition/framing and where the moving elements will move from and to are
important.)

7.Photo-editing software

How to make a sequence
1. Select the images your going to use and open them on photoshop(making sure they don't touch
each other)
2.Select the second image using Select then all
3. Go to edit then copy
4. Go on to the background image then go to edit then paste
5. Then mask the image using the mask tool
6. Make the layer black by going on edit, fill and change it to black
7. Select a brush making sure it is 100% then paint in the person
8. Repeat the process 

Final image

       

         I think the image is a bit too bright, which has made it slightly out of focus. I also think that the gap between the first and second sequence is to big, but I couldn't use the image in-between as it was touch the second sequence. The sequences shouldn't be touching. If I use this technique again I'll do it twice to create a better final image. I'll also make sure the sets are correct accounting for the amount of light.

Techniques-Animated GIF

Animated GIF

Definition- An animated GIF is an image encoded in graphics interchange format (GIF),which contains a number of images or frames in a single file and is described by its own graphic control extension. The frames are presented in a specific order in order to convey animation. An animated GIF can loop endlessly or stop after a few sequences.

How to create a GIF
1. The size of the file to 72 dpi, and 900 x 600 pixels by seleting image, image size. Remebeing to change the centimetres to pixels
2. Load all images on to photoshop
3. Layer them the same way as a sequence
4. Select window, then timeline
5. Create a video time line
6. Drag the image into the timeline and adjust each clips duration. e.g 5 frames
7. Test it by pressing the play button
8. If fine loop the video you will need to select the select the playback option button and then press play
9. to save the GIF select file, save for web and select GIF file and 128 dithered

Final image

I feel the image has a flowed mostion, but the lighting isn't great. If I use this technique again in the future I'll double check that the settings are correct, which will make the final image look clearer.

This works as the daisies look bigger then normal. The daisies look like the same size as the blu door to the right. The grass to the left looking closer in size to a tree.


The subject of this photo looks bigger then the house. The theory is correct yet I wasn't careful enough pressing the button as I shacked the tripod, making the image unclear.

Images that require improvement

The lighting isn't bright enough and isn't wide angle close up.


The left dose look bigger then the buildings in the background but it is too blurry.
