What shortcut key moves focus to the previous field of the current record?
In Microsoft Access, the shortcut key to move focus to the previous field of the current record is "Shift + Tab."
What is the difference between the terms 'long take' and 'deep focus' in photography?
I think your question could be re-phrased as the difference between long exposure photography and deep depth of field photography. A long exposure is where a long exposure time is used, either to record movement over a period of time, for artistic effect, or in order to provide a greater depth of field, (deep focus), achieved by using a smaller 'F' number on the camera, which provides a smaller aperture for the light to pass through. ********* For some, it relates to what is technically known as hyperfocal distance (a point of focus deduced and utilized to maximize depth of field beyond normal). IMHO, "deep focus" is a mis-nomer as you can only focus on one plane within the field of view. Anything in front or behind is not in focus; however, it may be acceptably sharp to the eye. This is depth of field. There is also "depth of focus", which is different, though related. Methinks neither depth of field nor depth of focus should be referred to as deep focus
What is the focus of the scientific field of biology?
Its the study of biology
What device uses lenses to focus light rays and record an image of an object on photographic film?
A camera uses lenses to focus light rays and record an image of an object on photographic film.
When do you use planes of focus and depth of field?
When you compose a shot.
What is the depth of field on a microscope?
Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
What is the difference between maximum depth of field and shallow depth of field on a camera?
Depth of field in photography is 3-dimensional and is measured from the foreground moving along a horizontal plane towards the background. Maximum depth-of-field means most of the scene is in focus and shallow depth-of-field means the minimum is in focus. Shallow depth-of-field lets you lose the background into a nice blur leaving the foreground in focus - good for portrait photography. In landscape photography you would normally choose the maximum depth-of-field so that distant hills were in focus as well as the middle ground and the foreground - in other words, everything in the field of your vision would be sharply focussed.
How do you adjust the slide when the specimen is out of the field of view to the top?
To adjust the slide when the specimen is out of the field of view to the top, gently move the slide on the stage towards you using the x and y-axis controls on the microscope. Start by adjusting the coarse focus knob to bring the specimen roughly into view, then fine-tune the focus with the fine focus knob until the specimen is in focus at the top of the field of view.
What is an instrument that uses lenses to focus and film and record an image?
Atomic bomb
How do you increase depth of field?
focus on the element u want to capture
How does F-stops effect on photography?
The depth of field(focus) and exposure.
What is a tool that uses a magnetic field to focus a beam of electrons?
A tool that uses a magnetic field to focus a beam of electrons is called an electron microscope. It uses electromagnets to control and focus the path of electrons, allowing for high-resolution imaging of very small objects.
