Mostly by reducing the number of colours in the pallet. Default pallets of have a lot of colours that are not actually in the photo, and removing those has absolutely no effect on quality. Some colours appear in a single pixel and will not be missed if blended with their neighbours. After that there is gradual degradation but many colours can be removed without the degradation being noticeable. Color depth - Wikipedia Online Image Сompressor

Most approaches will not hinder a screenshots, etc. There is no harm in mixing approaches, but watermarking is probably going to be the protection that works.

There is nothing worse than stumbling across the perfect crepuscular rays, setting the tripod up, changing the lens, switching filters, and then finding the clouds have moved :mad:

I ordered the Hoya because its currently on sale at Amazon. It's probably not be the best, and I don't have an ideal lens or an ideal location either. Here is a detailed article that explains the effects of UHC and CLS filters with some great shots of nebulas. How to Choose a Light Pollution Filter for Astrophotography

I would not buy mirrorless with the current technology. I rather viewed DSLR as the upgrade from mirrorless, but I am a male with large hands and an appetite for weather sealed bodies. If I were smaller or weaker then I might prefer mirrorless - think of the young people hiking with heavy DSLRs on their back! My view is that Pentax (or any brand) would do best to capture a person's loyalty with the first lens collection. Every new joiners to the K-mount world benefits me because more customers means lower prices, broader after-market support (e.g. Sigma), more DIY camera repair tips, and so on. Your point about the technology race is a valid problem, and that is why low-volume niche is a dangerous place to go. The worst place is trying to sell the "straggler" technology that can be cheaply replicated.

I have difficulty seeing distance haze. I have trawled through tutorials that show with & without haze, and apparently the difference is obvious, but to me they look alike. I do see that the UV filter tones down the powerful turquoise-blue in sunny skies, making the photo appear not-so-sunny after all, but I'm not sure that is adding realism. It bugs me that I cannot see what the experts claim is obvious. Is it just me?

I can learn from others how to see things differently, and that learning might change what I instinctively see. However, if I want to capture what I am seeing right now then over-thinking and choreographing is not going to produce the right result. Put another way, there is probably a best practice for walking, but using my own walk has always felt more natural to me.

The pandemic may have decimated sales of use-once family holiday cameras. I speculate that pandemic deaths may impact short-term used camera sales as many of the best camera collections are long-life collections. These factors may help explain why Nikon is now flooding the market and strengthening the foundations of its future. The pandemic creates a situation where many of us have a fresh chance to walk in isolation and take pictures of undisturbed wildlife - this is why I dusted off my old Samsung/Pentax DSLR. There is no immediate sale for Pentax, but focussing on "now" is a short-sighted view. The truth is that I am currently wedded to K-mount lenses and I may soon have a reason to pair those lenses with a new body, but only if there is an upgrade path. If it appears to me that a new Pentax body will be unsupported by third-party lens makers then I am going to recalculate the long-term value of keeping my existing collection.

The ability to experiment with legacy lenses was the K-01's unique product offering. The K-01 was a product failure because of unrelated oversights such as its unprofessional body. History of Apple shows what happens when the body is wrong - Apple had its brush with bankruptcy between Steve Jobs leaving and Steve Jobs returning. The lesson from Steve Jobs was that the "body", across all products, is the packaging and therefore the marketing. The K-01 had possibly the worst packaging, and hence the worst marketing, of any recent camera - the body was not ergonomic, and it was not familiar. The K-01's market failure is a reflection of flawed implementation, not a flawed idea.

I understand what Shinobu Takahashi is saying, but before critiquing I would like to consider a very quick whistle-stop tour of success and failure. Brand loyalty burns into the human psyche quickly and is then very difficult to dislodge. This is why SONY targets young people. It is why BMW can sell a 7-series to a retiring executive who fondly remembers his first company 3-series. It is why Microsoft sold every one of its original X-BOX consoles at a loss, and why SEGA is now defunct. The strategy used by winners is to always have a product that wins the heart of young customers, immediately burns brand loyalty into them, and sets up repeat purchases over a lifetime. These CEO games play out over decades and speculating success is hard, but discovering the formula for failure is really very quick. History shows that focussing all efforts on a group of loyalists is the beginning of the end, for any company, in any industry. The "cling to a niche" case study crops up in every business school syllabus. KODAK, after inventing the digital camera, refused to compete against its own 35mm film business - filed bankrupt in 2012. NOKIA, after inventing the touchscreen phone, instead focussed on its established niche - they are now defunct. There are many more examples, and my point is only that the recipe for failure is very well known. The observation is that the winner in this camera industry will be the company that places an affordable quality camera in the hands of first-time photographers, and maintains an upgrade path, thereby reaping the rewards of life-long repeat customers. I agree with Shinobu Takahashi that PENTAX should not compete in the pre-photography market space. The world of throw-away low quality snaps created with built-in miniature hidden devices is not a place where any company can build life-long customer loyalty. I also strongly disagree with Shinobu Takahashi that DSLR is the way forward because mirrorless has the customer first, and the upgrade path starts there. My view is that the PENTAX K-01 mirrorless camera with K mount was a near miss. The K-01 had some design weaknesses, and it was too expensive for beginner photographers, but it was a good weight for youngsters and it had a clear upgrade path. An improved K-01 could take photographers on a journey from humble beginnings to a flagship PENTAX K-1 II. PENTAX needs to try again and try to avoid repeating KODAK's mistake.

I hesitated because an entirely different list of unfamiliar (and much more expensive) products is being called out by astronomy blogs. Do they know something we do not? Best Light Pollution Filters for 2021 – Astronomy Online

Hi all, I live near a major city and I am looking for a bargain light pollution filter to hopefully capture night sky. Most of my lenses have a 52mm thread for filters. Can you please share tips on which brands/models to look out for?
