So photo will be dark.
It is often easier to shoot photos with
Use flash when object is less than 3 meters away.
Could use UV Filter Polarizer. Could use sun glasses. See what happens there.
When shooting against sun use fast shutter speed, and small aperture, so less light arrives but depth of field will be larger.

Lens flare is when non image forming light is in the image. Shoot away from source of light, or have a hood on camera.
Remember the rule of thirds is important where lines intersect.
In the context of lighting design, backlighting refers to the process of illuminating the subject from the back. In other words, the lighting instrument and the viewer are facing towards each other, with the subject in between. This causes the edges of the subject to glow, while the other areas remain darker. The back light is usually placed directly behind the subject in a 4-point lighting setup.
Contre-jour, French for 'against daylight', refers to photographs taken when the camera is pointing directly toward the source of light. An alternative term is back lighting.
So basically when you the photographer is looking at the sun.
AKA against daylight aka Backlighting
In photography, bracketing is the general technique of taking several shots of the same subject using different or the same camera settings. Bracketing is useful and often recommended in situations that make it difficult to obtain a satisfactory image with a single shot, especially when a small variation in exposure parameters has a comparatively large effect on the resulting image. Autobracketing is automatic bracketing by using a setting on the camera to take several bracketed shots (in contrast to the photographer altering the settings by hand between each shot).
So good idea perhaps to photo Northwards in morning in morning in the North.
The ability of an imaging system to resolve detail is ultimately limited by diffraction. This is because a plane wave incident on a circular lens or mirror is diffracted as described above. The light is not focused to a point but forms an Airy disk having a central spot in the focal plane.
Optimal aperture F8 to F11
Depth of field smaller at lower f numbers.
Will often get dark photos when shooting toward sun. Unless object is close an you can use a flash on the object.
Used the light. The sun.
In photography and optics, vignetting is a reduction of an image's brightness or saturation at the periphery compared to the image center. The word vignette, from the same root as vine, originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait which is clear in the center, and fades off at the edges. A similar effect occurs when filming projected images or movies off a projection screen, the so-called hotspot, defining a cheap home-movie look where no proper telecine is used.
Although vignetting is normally unintended and undesired, it is sometimes purposely introduced for creative effect, such as to draw attention to the center of the frame. A photographer may deliberately choose a lens which is known to produce vignetting. It can also be produced with the use of special filters or post-processing procedures.
So it is brightness and saturation declines with distance from image center.
So F32 would have bigger depth of field than f 5
Depth of field increases with f number.
F stop is number.
This is frequently useful for nature photography, portraiture, and certain special effects. The depth of field of an image produced at a given f-number is dependent on other parameters as well, including the focal length, the subject distance, and the format of the film or sensor used to capture the image.

Housing tenure refers to the financial arrangements under which someone has the right to live in a house or apartment. The most frequent forms are tenancy, in which rent is paid to a landlord, and owner occupancy. Mixed forms of tenure are also possible.
The basic forms of tenure can be subdivided, for example an owner-occupier may own a house outright, or it may be mortgaged. In the case of tenancy, the landlord may be a private individual, a non-profit organisation such as a housing association, or a government body, as in public housing.

Castletown is the former capital of the Isle of Man and site of Tynwald and can trace its roots back to 1090. The town has narrow streets and small fishing cottages. Fishing boats still continue to go out to fish from the harbour. Commercial traffic to the port ended in the 1970s, although there has been an ongoing expansion of finance and industrial businesses in the area.
The last person to be hanged on the Isle of Man was John Kewish in Castletown at Castle Rushen on 1 August 1872. In 1874, the House of Keys moved from Castletown to Douglas. The first telephones appeared in Castletown in 1901.
