By the way, one of my photographers took a group of photos of me with film, but they all came out so yellow. Does the film need repairing? ? Or just go out! ?

Photographs taken and developed with film are yellow.

The reason is:

1. When shooting, the color temperature of the light source is low, which leads to yellowing.

2. Color correction is not allowed when developing photos.

3. Improper proportion of washing liquid formula or inaccurate temperature control of liquid medicine. Fourth, the film has expired. ?

If the negative color obtained after film development is incorrect and can't be repaired, the color correction can be adjusted when the printer enlarges the photo. At present, all amplifiers are digital amplifiers. Film negatives can also be converted into digital images by scanners, and then colors can be corrected by software, and photos with accurate colors can be enlarged by magnifiers.

Extended data:

Film is silver salt sensitive film, also called film. Made of PC/PP/PET/PVC.

Film generally refers to film, but also refers to negative film in printing and plate making. Movies are all black. Generally, there is an English symbol on the corner of the film, which is the film number, indicating which film C, M, Y and K are, and which cmyk (or spot color number) is, indicating what color this film outputs. If not, you can look at the angle of the net to tell what color it is.

perform

1, which has excellent physical and mechanical properties.

2. Excellent impact resistance, high tensile strength, bending strength and compressive strength; Small creep and stable size.

3. It has good heat resistance 125 degree and low temperature resistance of-45 degree, stable mechanical properties, dimensional stability, electrical properties and flame retardant properties in a wide temperature range, and can be used for a long time at -60 ~ 120 degree; It has no obvious melting point and is in a molten state at 220-230℃. Due to the rigidity of polymer chain, the viscosity of resin melt is very high.

4. Low water absorption, low shrinkage, high dimensional accuracy, good dimensional stability and low film permeability; It is a self-extinguishing material;

5, stable to light, but not resistant to ultraviolet rays and good weather resistance; Oil-resistant, acid-resistant, alkali-resistant, oxidizing acids, amines and ketones, soluble in chlorinated hydrocarbons and aromatic solvents, and easy to cause hydrolysis and cracking in water for a long time. The disadvantages are poor fatigue strength, poor solvent resistance and poor wear resistance, which are easy to cause stress cracking, but the modified PC connecting adhesive is acid and alkali resistant.
