The ISO 800 rolled over the 3DX 6000 airport scanner 5 times, and it was basically scrapped. **From the web. Films with a sensitivity of ISO 400 or less are basically fine after one or two times, but rolls with an ISO of 400 or higher are suspended, and the higher the sensitivity, the greater the impact.

Not only high-sensitivity films, but also reversal films and motion picture films, try not to go through airport security. In particular, it should be noted that the X-ray power of different security screening machines is different, and if you are safe and sound at this airport, it does not mean that you can go to another airport to get the film out.

It refers to the X dose issued by the carry-on baggage screening machine (unchecked baggage screening) that does not cause visible damage to the film at a specific irradiation time (usually a few seconds). If you throw the film in the security machine for a few hours, then the film will also be scrapped.

In this case, it is generally said that the safety bolt or the like. For example, gun insurance is also called safe, and safe here does not mean safe.

It's just talking, and it will be ** if you take more photos.

In fact, I think the best scenery is to present the world through the lens of "me", the best portrait is that there is "me" understanding of "ta" in this work, and the best still life is the one that can express everything "I" want to express. Although photography is not among the eight major arts, it does not mean that photography is not art, it turns out that many good photographic works are good works of art, and in reality, photography majors also belong to the Academy of Fine Arts, so photography as an artistic career, its purpose is to express.

The purpose of my photography is to capture the beautiful moments of life.

Record images (i.e., history), including graduation photos, enrollment photos, weddings, news, travel, etc.

Artistic creation (commonly known as works).

Business services (advertising).

Keep the good times alive and remember the past.

Professional photographers are for life, and there are people who choose this job for the love of photography; I am a photography enthusiast, I use the camera in my hand to record the bits and pieces of life, freeze every beautiful moment; You can keep your youth, keep the beautiful scenery, and keep the past; When I'm old in the future, I can turn the ** out and see, and lo and behold, that's the young me back then, so meaningful!

If it's me, of course, it's to make money.
