Save the Antique Camera Bag - Paull Shoulder Camera Bag

The original Canon camera bag that came with my unit was still in good condition after over a decade of use, but for better organization and comfort, I decided to upgrade and purchased a single-shoulder camera bag. It's designed to carry a DSLR, a mirrorless camera, a flash, and is compact yet sturdy, making it both convenient and durable. Reasons to Buy: I've tried several brands for camera bags over the years, and I'm still using the travel shoulder and top compartment of the Sai Fu Tu F7. The Tianba shoulder bag is the most comfortable, though it looks more stylish than practical. I once bought the Shooting Treasure D400AW, but later found out it wasn't worth the price. Some domestic manufacturers now offer great photography kits. A year ago, my father bought a Paull bag, which was very affordable and easy to use. So I gave it a try myself — it started at around 200 yuan. After checking the dimensions, the bag can easily fit a 5D3, 24-70mm lens, and a 600RT. It’s perfect for my needs. Appearance Gallery Purchased directly from Tmall, the outer packaging was intact. Inside, it was wrapped in plastic. Front view shows a clean design. From the side, the tag design feels a bit basic. Looking from the back, it still looks decent. Opening the waterproof cover reveals a nice feature. The logo on the waterproof cover is clearly visible. The buckles are solid and feel good to the touch. Zippers are smooth and custom-made. Inside, there are multiple compartments and zippers, making it very organized. The bag is well-designed with thoughtful storage options. It can comfortably hold one camera body and one flash. The front pocket offers extra space for accessories. Memory cards are securely placed inside. Side pockets are spacious and flexible, adding to the convenience. One side even has a drainage hole. The drawstring design keeps everything secure. Inside the zipper, the pull tab is well-placed and easy to access. The front pocket is perfect for batteries and a card reader. A side pocket is ideal for a charger. The handle is thick and comfortable. There’s also a waist strap for added support. At the bottom, there's a rain cover for protection. A lanyard is included, along with anti-slip features. The shoulder straps are fixed with rubber bands — a small but functional detail. The hanging buckle is strong and reliable. Overall, the bag is well-built and practical. Experience Feelings This bag completely replaced my old antique-sized camera bag and is now my go-to for daily outings. It’s very convenient and functional. Summary Paull’s materials are solid, and the design meets the needs of everyday use. What could be improved is the overall aesthetic, such as the packaging and logo design. It still has that classic, homemade feel, reminiscent of older county-level factories. This kind of character should be highlighted. I would recommend this bag to photographers who don’t need high-end features but value practicality and durability.

High resolution
In order to realize a large-area high-resolution Liquid Crystal Display, it is usually necessary to use low-impedance metal materials, high-performance switching elements, and high-precision processing techniques. Aluminum is the most researched and used material for making TFT buses with low-impedance metals. By solving the problems of easy formation of hillocks, chemical corrosion and oxidation of aluminum, alloy methods (such as Al-Cu, Al-Si, Al-Nd and Al-Ti, etc.) and interlayer methods (such as Mo/Al/Mo) have been reported successively. , Cr/Al/Cr and Ti/Al/Ti, etc.), the alloy method is relatively simple in process, but the material has a higher resistivity. In May 1998, IBM developed a 16.3-inch ultra-high resolution (200ppi) a-Si TFT Display using Al-Nd alloy as the gate electrode, and mass production has been achieved. In April 1999, Toshiba introduced the 20.8-inch 16-SVGA (3, 200 × 2, 400) a-Si TFT-LCD, which can be said to represent the highest level of a-Si TFT-LCD in terms of high resolution and high capacity. .
According to Display Search in the third quarter of 2011, the global flat panel display research report "QuarterlyWorldw ide Flat Pane l Dis play Fore cas t Re port" pointed out that the average pixels per inch (ppi) in large-size LCD panels (>9.1 inches) ) Will grow from 88ppi in 2010 to 98ppi in 2015. The ppi of small and medium-sized LCD panels (<9.0 inches) will grow from 180ppi to 300ppi in the same period. With the rise of smart phones, mobile phones will be the most obvious application product for ppi's growth.
Another important way to realize high-resolution liquid crystal display is to develop LT p-Si TFT technology. The resolution of published p-SiTFT-LCD products is generally around 200ppi. Compared with a-Si TFT-LCD, LT p-Si TFT-LCD has a smaller volume of thin film transistors and storage capacitors. Therefore, it has a larger penetration area per inch, resulting in a brighter display. , And save more power. When the market demands higher ppi, low-temperature polysilicon (LTPS) technology becomes the best choice for manufacturing high-resolution thin-film transistor liquid crystal displays.

Contrast
The control ICs, filters and oriented films used in LCD manufacturing are related to the contrast of the panel. For general users, a contrast ratio of 350:1 is sufficient, but such contrast in the professional field does not satisfy users. Demand. Compared with CRT monitors easily reaching 500:1 or even higher contrast, only high-end LCD monitors can achieve this level. The first-tier LCD monitors on the market, such as Samsung, Asus, LG, etc., can reach a contrast ratio of 1000:1. However, because the contrast is difficult to accurately measure with instruments, you have to go and see it yourself when you pick it.
Tip: Contrast is very important. It can be said that the selection of LCD is a more important indicator than bright spots. When you understand that your customers buy LCDs for entertainment and watching DVDs, you can emphasize that contrast is more important than no dead pixels. We When watching streaming media, the brightness of the source is generally not large, but to see the contrast of light and dark in the scene of the character, the texture change from gray to black hair must be shown by the level of contrast. The 256-level grayscale in the test software In the test, more small gray grids can be seen clearly when looking up, which means that the contrast is better!a
