I would like to ask, one of my photographers used film to take a set of photos for me, but the pictures came out very yellow. Does the film still need to be retouched? ? Or come straight out! ?

Shooted with film, the color of the developed photos is yellowish.

The reasons are:

1. When shooting, the color temperature of the light source is low, resulting in a yellowish cast.

2. When developing photos, the color correction is inaccurate.

3. The formula of the flushing liquid is inappropriate or the temperature of the liquid is not controlled accurately. Fourth, the film has expired. ?

The negative film obtained after film development has a color cast. If the color cast cannot be repaired, the color correction can be adjusted during printing by the printer. Today's enlarging machines are all digital enlarging machines. Film negatives can also be converted into digital images through a scanner, and then software can be used to correct the color, and the enlarging machine can be used to enlarge and print photos with accurate colors.

Extended information:

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

Film generally refers to film, and can also refer to negatives in printing and plate making. Films are all black. There is usually an English symbol on the corner of the film, which is the film number, indicating which one of C, M, Y, and K the film is, and one of the cmyk (or spot color number) , indicating what color this film is output from. If not, you can identify the color by looking at the angle of the net.

Performance

1. It has excellent physical and mechanical properties.

2. Excellent impact resistance, high tensile strength, bending strength and compressive strength; small creep property and stable dimensions.

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

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

5. Stable to light, but not resistant to ultraviolet light, good weather resistance; resistant to oil, acid, and It is resistant to strong alkali, oxidizing acids, amines and ketones, and is soluble in chlorinated hydrocarbons and aromatic solvents. It is easy to cause hydrolysis and cracking in water for a long time. The disadvantage is that it is prone to stress cracking due to poor fatigue resistance and poor solvent resistance. The wear resistance is poor, but the modified PC connection glue is acid and alkali resistant.
