Lens Hoods Also Provide Some Physical Protection While lens hoods are mostly for blocking light, they also provide a small amount of physical protection. If you’re shooting on a rainy day or near a waterfall, for example, a lens hood can shelter the front of the lens from some of the droplets. It’s not a replacement for an umbrella, but it can give you a few moments to get a shot before your lens is covered in water and unusable. … [Read more...] about What Does a Lens Hood Do, and When Should You Use One?

Oppo has been steadily building a portfolio in the budget smartphone segment under its A series. The Chinese smartphone maker had launched the A52 smartphone in the Indian market at Rs 19,990.

Among the other improvements enabled by the latest version of Google and Apple's API is the removal of so-called "ghost notifications", which previously occurred when the app's algorithm was working to calculate a user's risk threshold. This led to notifications of "possible exposure", which many users reported receiving, leading to confusion even in the case of a low-risk contact. … [Read more...] about NHS contact-tracing app upgrade is more likely to warn users to self-isolate
Alternatively, you could include a white card in a few of your early shots during that session and then use the white card as a reference point in post-processing to provide a white balance value for the remaining photos shot under the same conditions. This method is quite effective when done correctly, but it’s both time consuming and expensive (as basic photo editing software doesn’t include the kind of functionality you need to apply a custom white balance value across a whole set of photos). Another issue with this workflow is that just changing the angle the white card is photographed at can significantly change the values it produces in the photo. Using a white card appears quite simple but it actually a tricky skill to get just right. … [Read more...] about How to Achieve Perfect Photo Color with a White Balance Cap
One odd thing about the Surface Duo is that it kind of feels like you could pick it apart with your fingernail. The plastic sides don't wrap around the inner or outer glass at all, leaving the sides of the glass panels exposed. There's actually a gap between both panes of glass and the plastic edges, and you can easily stick a piece of paper in there, or even a fingernail. It's an odd way to make a phone, where normally the glass would be recessed into whatever material the sides were made out of, and any gaps would be impenetrable. If Microsoft had wrapped the plastic edges up around the glass, like normal, the area around the easily-broken USB-C port would be about twice as thick, while the overall phone wouldn't have been any thicker, which seems like a good idea! Obviously, after this description, the phone is in no way water-resistant. … [Read more...] about Surface Duo review—Orphaned Windows hardware makes a poor Android device
