Lamp panel
The lamp panel is divided into ordinary infrared lamps (Dingyuan and Guanglei) and array lamps. The array camera is also divided into 1W, 2W and 3W. Therefore, when choosing infrared lamps, if it is an ordinary infrared lamp, try to choose Dingyuan and 3W array lamps. Since the appearance of infrared lamps is generally invisible, some cottage cameras are filled with Guanglei and 1W array cameras are filled with 3W array cameras. Therefore, try to choose a large brand when choosing cameras.
Maximum Aperture
The real value of the maximum aperture is to improve the light intake under low light conditions, so as to achieve the best exposure combination. In general, the ability to visualize the lens is not required for shooting landscapes. In addition, the lens caliber is not required for shooting landscapes except in particularly dark places. However, when the 70-200mm zoom lens is equipped with a 2-fold zoom lens to make the telephoto section become 400mm and AF is used for automatic focusing, it is better to choose a lens with the largest aperture of F2.8. Large aperture is conducive to accurate focusing in dark conditions. When shooting people with a large aperture lens, even in places where the light is weak, the handset can also use natural light to shoot. In addition, the lens with the largest aperture can bring fast shutter speed, so sports photography also needs a large aperture lens.
Another reason for requiring the lens aperture to be large is to be able to visualize the background freely and ensure the quality of visualization. When the aperture of the lens with the maximum aperture of F1.4 is reduced to F2, both the imaging quality and the blurring quality of the background are better than those of the lens with the maximum aperture of F2. Therefore, it is of great value to reduce the aperture of a large aperture lens by one stop. Any photographer should be good at using the lens.
focal length
The first thing to pay attention to when selecting a lens is the focal length of the lens. In fact, focal length is a matter of perspective. Different focal lengths and perspectives are different. In addition, users should be clear about what is the main purpose of buying lenses? Is it for scenery or people. As we all know, it is better to use a wide-angle lens when shooting landscapes, and a telescopic lens when shooting people. Therefore, you should first decide the focal length of the lens you want to buy according to the purpose of photography.
The best focal sections for shooting scenery are 24 mm wide angle focal section and 200 mm telescopic focal section (both are based on 35 mm specifications, the same below). When the wide-angle focus segment of the standard zoom lens evolves from 28mm to 24mm, the viewing angle becomes larger, and the range of scenery that can be stored is greatly expanded. Generally speaking, the maximum aperture of the lens is not required for shooting landscapes. If you are mainly shooting landscapes, a wide angle focal length of 24mm is basically enough when you select a zoom lens. As for the telephoto section, it must be at least 200mm. If the telephoto section is 300mm or 400mm, it is more ideal, and the degree of freedom will be greatly improved. The telephoto focus segment of traditional zoom lens is 300 mm, which is 450 mm for digital SLR. The focal length has been expanded by 1.5 times, which makes it more enjoyable to use. This is the value of digital SLR. The wide-angle focal section of the digital special ultra wide-angle lens produced is generally 12mm, equivalent to 18mm of 35mm, which is nearly 1.5 times larger than the 28mm focal section of 35mm, thus greatly widening the left and right range of the scenic scene.
The best focal length for shooting people is 85mm. In terms of 35mm standard, 85mm focal length is basically used as the standard for shooting characters. The portrait taken by the 85mm focal section is basically close to the picture effect taken by the medium frame camera. It is not only suitable for the distance, but also the face of the person looks very natural. The distance between the camera and the person being photographed can basically be kept at the normal speaking distance. The 85mm focal length can also effectively blur the background and prominent characters. In order to obtain good visualization effect, the lens with the largest aperture should be selected. The 85mm focal length is about 135mm on the digital SLR. Although the sense of distance of the shot is a little weak, it is basically OK, so the focal length of the person lens should be at least about 85mm.
A 100mm macro lens is enough for traditional SLR to shoot flowers. The 100mm macro lens can be used for equal magnification photography, which can make the flowers very large. However, when taking equal magnification photography or near equal magnification photography, due to the depth of the long focus scene, it is easy to shake, so anti shake measures should be considered when taking photos. From this point of view, 50mm macro lens is easier to use on digital SLR.
The Great British Bake Off/Baking Show – Week 6 – Autumn 2024
It feels like we’re halfway through this season of *The Great British Bake Off* already! This week’s theme was all about “autumn,†and the bakers were challenged to bring their A-game to capture the essence of the season.
---
The **signature challenge** asked the contestants to create a sweet autumnal pie with pastry and seasonal produce, all within 2 hours and 45 minutes. Nelly, who has quickly become a fan favorite, wore an autumn-inspired headpiece that looked absolutely stunning. I laughed when she mentioned her connection to owls—“Owls live in the night just like me.†That resonated with me because I’ve always been drawn to the quiet beauty of nighttime, whether it’s cooking, reading, or enjoying a cozy movie night.
Nelly crafted a traditional Slovakian pie called *Jabikové Pité*, which is a classic that features poppyseeds—a staple in Slovakian cuisine. As someone who loves poppyseed desserts, I appreciated her choice. In fact, I even dug up a similar recipe from my own archives—Slovakian apple and poppyseed pie from *Relaxed Recipes*. Nelly admitted her pastry included baking powder, which made it tricky to manage the thickness. Interestingly, the photo accompanying the recipe resembled her pie closely.
While researching the use of baking powder in pie dough, I came across an insightful article from *The Kitchn*. Jessie Sheehan highlights how baking powder contributes to a tender and flaky crust, referencing Rose Levy Beranbaum’s *The Pie and Pastry Bible*. It’s fascinating how a small ingredient can make such a big difference!
Other bakers experimented with diverse styles. Gill went for a margarine and lard crust, reminiscent of her mom’s recipe for a blackberry and apple pie. Dylan ventured into the world of laminated rough puff pastry for his apple and cider pie. Illiyin created a blueberry, ginger, and pear pie, while Christiaan opted for a pumpkin and quince pie. Sumayah took a bold step by adding dried beetroot and spinach powder to her crust for a beetroot custard pie. Though some bakers struggled with overbaked or undercooked crusts, others excelled in their presentations.

In the **technical challenge**, the bakers were tasked with making sticky vegan parkin cut into 16 squares in just 1 hour and 30 minutes. Prue Leith set the stage, and Gill correctly anticipated the challenge during her interview—but then she forgot to add the baking powder! Ouch. The judges ranked the results as follows: Gill in last place, Sumayah in third, Georgie in second, and Illiyin in first. Darcie wisely noted how challenging these blind challenges can be, especially since even seasoned bakers sometimes struggle when they don’t know what the final product should look like.

For the **showstopper challenge**, the bakers were asked to create an autumnal festival cake featuring vegetables, with only 4 hours to complete their masterpiece. Dylan faced a major setback when he accidentally dropped a freshly baked layer onto the floor en route to the freezer. Fortunately, he had leftover batter in the fridge, so he managed to recover without losing too much time.
Sumayah wowed everyone with her autumn leaves cake, which combined beetroot, ginger, walnut, and parsnip layers topped with flaked almonds. Both flavor and presentation earned her high praise. Paul declared it the best cake he’d ever tasted, and Prue couldn’t stop raving about her talent. Christiaan, Gill, and Illiyin also received commendations for their creations, though Georgie’s cake was deemed overly dense despite its good flavor.
Dylan’s monochromatic cake, featuring beetroot, orange, and cardamom flavors with cream cheese frosting, impressed visually with its white chocolate peacock centerpiece. However, the judges felt the overall design was a bit messy. Still, I personally thought it was breathtaking.
Nelly, unfortunately, overcompensated in her effort to impress, resulting in too many competing flavors in her showstopper. While her design was praised, the complexity of her approach didn’t resonate with the judges.
---
The **results** brought mixed emotions. Sumayah earned the title of Star Baker for her exceptional showstopper, proving she’s a force to be reckoned with. My heart sank when Nelly was sent home, though her graceful exit and inspiring words left a lasting impression. She emphasized teaching her kids to savor the joy of baking rather than focusing solely on winning, and she promised to leave a piece of herself behind. Truly remarkable.
As much as I hate to see her go, Nelly’s spirit shines brightly, and I’m confident she’ll continue to inspire others through her passion for baking. She deserves her own cookbook—trust me, it would sell like hotcakes! Until next week, happy baking!
