Is there any difference between a photo with a blue background and a photo with a red background? There are strict requirements for personal identification photos, which is estimated to be common in graduation photo!
What's the difference between a negative and a photograph? There is a difference between the two.
When taking photos in a photo studio, if the traditional camera takes negative photos, you should give them both after payment, while the digital camera does not take negative photos, but only stores the image information in the digital camera (in fact, this image information is "negative", but there is no film object), so you can "copy" the photos with this electronic image information.
In this case, after payment, he only gives photos;
If you want to download the electronic version, you may have to pay extra.
What's the difference between BB cream and liquid foundation? BB cream, also known as light spot balm, was originally a regenerative cream, which was used to protect and repair damaged and damaged panels after plastic surgery, and also a medical scar maintenance cream. Its main functions are concealer, skin tone adjustment, sun protection and pore thinning, which can create nude makeup effect, and the newly added skin care ingredients can also improve the problems of the panel. Liquid foundation is liquid foundation, which is the last step of skin care and the first step of makeup. Its function is to prevent dust in the air from entering the panel, so it plays a protective role. Generally speaking, the concealer effect of liquid foundation is better than BB cream, and BB cream is more skin-care than liquid foundation. However, different brands of BB cream and liquid foundation have different effects. Some BB cream conceals blemishes better than foundation, and some liquid foundation moisturizes more than BB cream. That depends on what you need when you buy it. However, it is not recommended to use both when applying makeup. When removing makeup, you need to remove makeup like makeup.

Insurance, medical insurance, IC card, temporary residence permit, wedding photos.
What's the difference between a photo and a ct photo? Essentially, it is obtained by detecting the X-ray signal transmitted by the human body, directly forming a digital image, and the digital image data is transmitted to a computer to form an image.
In essence, CT film scans a certain thickness layer of human body with X-ray beam. X-rays passing through this layer are received by the detector, converted into visible light, converted into electrical signals through photoelectric conversion, and then converted into numbers through an analog-to-digital converter (*** og/digital converter), and input into the images formed by computer processing.
Simply put, X-rays are formed by projecting every "point" of an object, such as a person, onto a plane.
Ct: Actually, the human body is divided into many layers, that is to say, suppose that the human body is divided into several layers, with a layer of 3 mm, and then the projection of each layer is collected into a CT image.
In terms of effect, ct is actually an evolutionary form of X-ray film, which is due to the development of X-ray tomography technology. To put it bluntly, CT is a more complicated "X-ray"
I wonder if you can understand this. If you are a patient, I will tell you two simple differences. First, CT is more expensive. Secondly, CT is more accurate than X-ray in seeing most diseases. It's that simple.
What's the difference between 2-inch photos and 2-inch photos? The differences are as follows:
A 2-inch one is clearer than a 2-inch one.
Two inches or two inches requires more storage space than two inches.
Three sizes are different
Four. The ID photo usually needs a 2-inch photo, which is not the right size and cannot be used.
What is the difference between the use of cement 325 and cement 425? The bigger the label, the better the compressive and tensile strength. Generally, 325# can be used to stick bricks. If the label is too high, it is easy to crack the brick. Generally, cement labels are 325, 425 and 525, and the higher the label, the more expensive it is. The validity period of cement is generally 30 days.
The label of cement is the index of cement "strength".
At present, cement produced in China generally has several labels, such as 225 #, 325 #, 425 # and 525 #. Different grades of cement are produced to meet the needs of preparing different grades of concrete.
Cement, powdery hydraulic inorganic cementing material. Mud can be hardened in air after being mixed with water, and the hardening effect is better in water, and materials such as sand and stone can be firmly bonded together.
The word "cement" is developed from the Latin caementum, which means crushed stone and flaky. The history of cement can be traced back to Dadiwan people in Qin 'an, China, 5000 years ago. They paved the ground similar to modern cement. Later, the ancient Romans used a mixture of lime and pozzolan in their buildings, which was very similar to modern lime-pozzolan cement.
After hardening, the concrete made of crushed stone cemented with it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it has been widely used in civil engineering, water conservancy, national defense and other projects.
