What are the advantages and disadvantages of Daguerre photography and Carlo photography?

Carol photography is a photography method from negative to positive, that is, first take a negative of a photographic paper, and then print the photo on another photosensitive paper with sunlight. Compared with Daguerre photography, both have their own advantages and disadvantages.

Advantages of Daguerre photography:

1. The image texture is very clear.

2. The exposure time is short.

3. The production time is short, and it can be delivered soon.

4. Not easy to fade.

Disadvantages of Daguerre's photography:

1. A metal plate can only get a direct positive image.

If you refuse to revise, all the shortcomings on your face will be exposed.

3. The image is left and right.

4. It is expensive and needs a silver-plated metal plate.

Advantages of Carlo photography:

1. You can print unlimited photos for each negative at a lower price.

The negative can be modified to remove wrinkles and spots on the face.

3. The image in the photo is not left or right.

4. Photos printed on paper are not only easy to watch, but also easy to post and post.

Disadvantages of Carlo photography:

1. The image texture is rough and uneven.

2. Low photosensitivity and long exposure time.

3. It takes a long time to make, and the negative should be dried, then developed and dried.

4. Easy to fade.

By comparison, we can find that the biggest advantage of Carlo photography is that after the negative is taken, it can print and print photos indefinitely, and the cost is low. This advantage was ignored by people at that time.
