Inktober already

In case you hadn’t noticed I haven’t been posting much here, Mainly because I had eye troubles (again) and couldn’t see. So any computer work was a total strain. I also hadn’t done anything on social media for a couple of months, which was a good thing really. Instagram is really the only thing I check occasionally these days. However my eye is getting better and I have previously enjoyed doing the Inktober challenges. So I’m going to try draw something every day this month. Following their official prompt list.

The first topic is pretty simple. It’s Apple. First of all I thought of trying to draw a laptop with an Apple logo. I’m not an Apple fanboy and I don’t have any apple gear so forget that. Instead, I just got a nice green apple put it on the table after breakfast got out a new sketch book and my new favorite Tombow pens. Keep it simple, no need to go overboard on the first picture.

Now to keep going every day for the rest of the month.

Yet Another Microsoft Copy Disaster

 I'm still cleaning up old computer files, and I've been moving non-photo and non-video stuff into a miscellaneous folder on a USB backup drive. Eventually that drive got full, so I decided to move everything to my studio external hard drive, which still had space.

 A few nights ago, I plugged in the USB drive and started copying a large directory with multiple subdirectories over to the external drive. I didn't use TeraCopy (hadn't installed it yet) and just did a standard cut and paste operation. I didn't really check how long it would take, but based on the speed, I figured it would run for hours.

 I’ve got an eye infection that needs my attention, so I left the copy process for a couple of days. When I finally checked back on it, something had clearly gone wrong. There was a fresh login screen The computer had obviously rebooted. Only a handful of files had actually made it to the external drive, nothing like the multitudes I was expecting.

 What happened? My computer had upgraded itself without my permission. I'd specifically asked to delay updates for five weeks, but Windows did it anyway and apparently killed the entire copy operation without giving me any error messages or warnings that something went wrong.

This is exactly the kind of frustration that's been building with Windows 11 over the past six months. Yes, I could have done better by installing TeraCopy first and actually monitoring the process. But the real issue is that Microsoft's system silently failed without telling me anything was wrong.

I've totally lost faith, I cannot honestly rely on Microsoft anymore.

Teracopy is available on the Microsoft Store, but to find it you must spell it exactly without the double r and it should be the first item on the list and have an page that looks like the one on the righr. It is free. It’s simple to use and works fine

Can We Trust Them?

I got one of those promotional emails from Google Workspace recently, pushing "Ask Gemini in Drive." Their pitch: get synthesized answers pulled from multiple files, no need to actually find and read them yourself.

Sounds convenient. But here's the thing I believe strongly in this age of AI slop and post truth internet you must always check your sources.

If there's a conspiracy or cartel among tech giants, it works in two parts.

First, they're slowly weaning us off our own capabilities. Our own PCs, our own software, our own data, our own creative work. Everything gets pushed toward a thin client model where it all lives in the cloud. Their cloud. Their software. Your data, despite endless assurances it stays private (except for training purposes, except for testing, and so on, have you actually read the updated terms of service lately). That means they control everything. Sound familiar? Too much like Orwell's Big Brother?

Second, while some features stay free for now, it quickly becomes clear you'll need to subscribe, and not just to one service either. The real hidden cost will be cloud storage, and eventually being locked out of what's actually yours. I'm not exaggerating. OneDrive has already started doing this, and not just to me.

So we'll be handed answers without needing to think, but we could pay dearly for the privilege.

Is this nirvana, or is it dystopia?

Frustration Central

I lost some of my working computer files earlier in the year and confidence in Microsoft.. My office computer died right after a Windows update, and it caught me between backup cycles. About a month of photos was only partially saved. Not great!

Firstly I stepped back and looked at what I need to do to make sure it doesn't happen again. This lead to going back through all my backups and archives. It wasn't a happy task many of the archive sets were missing a significant number of files and several were of zero length. It took a while to track what was happening.

The problem turned out to be a short-coming of the copy function in Microsoft windows when copy multiple nested directories in an unsupervised way. The copy function can hit a file it can't copy and it then moves onto the next directory leaving the rest of the directory or directories not copied. Occasionally it sems it just created an empty file header and moved onto the next file. These missing files only showed up with detailed review. The number of files in the affect directories would become less in subsequent copies or the amount of disk pace required would become slightly lass. Empty files where easy enough to find once I knew What I was looking for. My adoption of creating at list of the MD5 checksums a few years ago really helped zero in on problems in recent year. 

For a short time I was side-tracked by the unnoticed update in windows 11 that copied my working directories of photo into a subdirectory under OneDrive and then started uploading them to the cloud, and worst still starting to remove older files from my computer (all unknow to me).

Turning off the link to OneDrive, was the simple solution. But microsoft seems to be able to turn on the "private" OneDrive after it updates (now manditory in window 11 home. Arrggghh!

This is unacceptable behaviour microsoft

I searched through every backup or archive I had and saw the pattern where files disappeared during times where I bulk copied many directories. Looking in forum and targeted web searches I found I was not the only one who noticed this and found most highlighted the bulk copies of directories although there was a variety of reasons suggested as to why.  Not checking the copy I had left myself open to both such problems,  The other likely cause was "data rot", from earlier backup sets that used DVD and CDs as the backup media. I also have been using old hard disk from computers that died from update in my air-gapped backups/archives, and t was possible that these might suffer from  a process known as magnetic decay or "bit rot", but I could not find any evidence of this even in disks tat had not been fred up in 3 years. Solving both these issues lead me to Teracopy because it does have the  option to verify files after copy to ensure they are identical.. It is nice and simple and works,

It was complex figuring out how best to compare a range of "incomplete" backup set I already had and just find one good copy of each photo. The crux of the problem is; I had no simple way to know what was missing and/or what might be corrupted. I realized that my "air gapped" copies on old harddrives would be a nice starting point. It was

So in the end I returned to the 3-2-1 with 1-0 extension as the best method of backup and keeping an archive of my photos. I've modified the process a little, I don't keep my off-site backup in the cloud and I use Teracopy, XNview MP to look at photos as images and the MD5 checksums to ensure that my photo collection is free of errors.

DIY Calibration Chart

 A DIY Calibration Chart for Photographing Your Art (No Expensive Gear Needed)

Ever taken a photo of your artwork only to have it look completely different once it's online? You're not alone. Professional calibration tools from companies like X-Rite or Datacolor Spyder can help fix this, but they're expensive and actually only work on devices you control. The real problem is you have no control over how someone else's screen displays your image.

So, I created a simple chart to tackle the biggest issues that come up when photographing art for the web. It’s a low cost printable calibration chart you can use any time you photograph your art to be shared on-line.

Getting Started

Download the chart (as a .jpg file) and print it at 4 by 6" (10 by15cm) on photo paper. Choose matte or semigloss over glossy to avoid reflections. Any inkjet printer works, or take it to a photo print service like Ted’s, Officeworks or Harvey Norman.

You can use the chart before you shoot, or after, when editing. Fixing lighting issues before you shoot saves time and gives better results overall. Just place the chart on or next to your artwork, under the same lighting conditions.

Why Dynamic Range Matters

Dynamic range describes how much detail a camera captures from shadow to highlight. Your eyes handle huge contrasts easily, from sunlight to starlight, but cameras struggle. That's why bright skies blow out to white or shadows go pitch black in photos.

The chart has grayscale steps down each side, each representing a 2 percent shift in light intensity, plus small target circles for finer detail. The more steps you can distinguish in your photo, the better your lighting is working. If steps disappear into the background, especially on the darker side, add more light, but don't overdo it or you'll blow out the highlights.

With practice, you'll learn to spot overexposure (dark steps look too light) and underexposure (light steps look too dark) just by reviewing the upper or lower greyscale on the chart.

This trick works after the shoot too. Use your photo editing software's exposure, contrast, and shadow/highlight sliders can make changes on your photo containing the chart, then copy those settings to the rest of your batch. Thus you only need the chart in one reference photo per series where all the photos are taken umber the same conditions

Colour is trickier than tone. Our eyes adapt to lighting variations automatically; cameras don't. The chart includes seven reference dots, six colours plus black, representing the core building blocks of the sRGB colour space used in jpeg files. The table below show how each of the tiny coloured lights (red,green,blue) on your TV screen of computer monitor are lit up to get the given colour. Zero indicated the light is off and 255 that the tiny light is fully on. These lights then make up a single pixel within the photo image.

(255,0,0)         R            0 Red
(0,255,0)         G            Green
(0,0,255)         B             Blue
(0,255,255)     C            Cyan
(255,255,0)     Y             Yellow
(255,255,255) M            Magenta

After taking the photo, you could use a colour picker to compare your photo's dots against these values. This won't give you pixel perfect correction, but it'll reveal a colour cast. The main thing to watch for. Do the dots still look clean and bright, or dull and grey?

Dealing with A Colour Cast

Colour cast is sneaky because your brain corrects for it automatically without you noticing. Old incandescent bulbs throw a yellow-orange tint; overcast daylight can add a blue tint. Reflections from walls and furniture are often the biggest culprits, since your brain filters these out but your camera doesn't.

To check for colour cast, look at the white background behind the chart's colour temperature panel. If the white looks yellowish or bluish instead of neutral, you likely have a bias. The nine squares can help confirm this.The three colour squares of the same colour as the bias will appear brighter and/or stronger, while colour on the opposite side will appered duller or darker.

The fix is usually simple, find better light. If using artificial light, Daylight LED bulbs (around 5000k) are cheap and reliable. If using natural light, shoot in soft shade rather than direct sun, like near a window indoors, under a veranda, or in an open garage. A white board opposite your light source can bounce light back and soften harsh shadows.

When editing, use white balance, warm/cool sliders, HSL adjustments, or LUTs, always test these changes on your reference photo first before applying to the batch.

One Final Tip

Avoid the saturation slider orfilters when photographing art. They can make your image look garish, especially on screens where the viewer has already boosted their own contrast and saturation. If colors look flat, use the vibrance slider instead, and go easy with using it.

With this one printable chart, you can catch lighting and colour problems before they ruin your photos, and fix them quickly if they slip through. No expensive gear required.

Introducing a DIY Calibration Chart

Why You Should Calibrate Your Screens (And How This Little Chart Helps)

Ever wondered why a photo looks perfect on your phone but flat and washed out on your TV or a print? It is not you. It is your screens. Even the best cameras, monitors and printers cannot capture or display the full range of light and colour that your eyes can see. That is where a simple calibration card comes in, and once you understand how to keep your equipment acceptably accurate.

Photographers talk about dynamic range, the span of light a device can capture, measured in stops. Each stop doubles the amount of light involved. Your eyes can handle around 15 stops. A good modern camera manages 9 to 11. Most TVs and monitors only reach 7 to 9, and even quality printers top out around 6.5.

That gap matters. When a device cannot handle the full range, it clips the extremes. Dark tones near black collapse into pure black. Bright highlights blow out into pure white. Detail and colour simply disappear at both ends.

Colour is its own puzzle, it doesn’t really exist as something physical, and there are two divergent interpretations of what creates it. How a device captures and reproduces colour is pure physics and maths of energy and light. How your brain perceives colour is much more personal, shaped by cognitive psychology and the lighting around you. Neither view is more "correct" than the other. The calibration chart will not give you laboratory precision, but it will nudge your average colour rendering and tonal contrast in the right direction.

Step One: Calibrate the Input (Your Camera or Phone)

Tonal calibration, getting the brightness and darkness levels right, is the single most useful adjustment you can make for realistic photos.

Look at the calibration chart and you will see a grey scale gradient running from black to white, with small grey rectangles down each side. On the right, the rectangles start light grey and get progressively lighter toward an almost white target. On the left, they start darker and step down toward a very dark target. Each little step represents a 2 percent shift in light intensity.

Here is the trick: point your camera or phone at the chart and check how many of those rectangles you can actually distinguish. You will probably lose a few, especially near the very dark or very light end. That is completely normal. Digital sensors simply cannot match your eyes' range, and cameras are designed to expose for an average middle grey tone anyway, so they will usually “clip” the extreme tones.

Start with your camera on an automatic exposure mode (A, P, or the green auto setting on a DSLR or mirrorless camera, or the default mode on your phone). Manual exposure is not necessary here.

Check the result somewhere you can actually see the screen properly. Camera and phone screens are notoriously hard to read in bright daylight, so review indoors or in shade.

If you can only spot a few rectangles on the dark side, the chart probably needs more light. If you cannot add light, try adjusting the exposure value (EV) on your camera or phone instead.

Advanced camera calibration (colour accuracy, white balance, lens distortion, sharpness) varies wildly between brands and models, so this card will not replace a proper colour profiling system. What it can do is flag obvious problems, like a consistent colour cast, or tonal issues worth investigating further.

Step Two: Calibrate the Output (Your Screens)

Now views a photo of the ca on your monitor, TV, phone or projector. This is where brightness and contrast come in, usually tucked inside a picture or display settings menu, accessed through a settings button or remote.

Start with brightness. Push it up and the screen gets lighter, revealing more rectangles on the dark side. Pull it down and you will see more detail in the light rectangles instead. The goal is a balance where you can see a good number of steps on both sides.

Next comes contrast. This stretches or compresses the range of visible tones. Getting it right is a bit of a balancing act between contrast and brightness. If you can see plenty of rectangles on one side but hardly any on the other, nudge the contrast up slightly, then pull brightness back to rebalance.

A quiet warning here: if you regularly use your screen in a bright room with strong light behind you, chances are your contrast is already cranked to maximum, which clips both ends of the tonal range. If that sounds like you, reset contrast to the middle, adjust brightness first, then slowly bring contrast back up while rebalancing.

Screen technology has changed a lot over the decades, from old cathode ray tubes to today's LED and LCD panels, and every manufacturer implements these settings a little differently. Materials also degrade over time, which is worth remembering if your screen seems duller than it used to be. When in doubt, the factory reset option is usually a safe, well calibrated starting point.

Step Three: Get Your Colours Right

Once tone is sorted, it is time for colour. Look for settings labelled colour, tint, colour temperature, hue, saturation or intensity, though the exact wording  and what bit changes depends on your device.

Saturation is often cranked up by default to compensate for ambient light, so check the row of coloured dots on the card. They should look natural sitting against the mid grey background, not artificially intense.

Many screens also offer picture modes such as vivid, natural, cinema, standard or eco. These bundle together saturation, brightness and contrast settings, so cycling through them is often the fastest way to find something that suits your eyes, though be aware they can override the careful brightness and contrast work you just did.

The chart itself has a colour temperature section running from warm reds, oranges and yellows through to cool blues and violets, sitting on a clean white background. If that background does not look properly white, you likely have a colour cast issue.

Small reference squares next to this section are arranged in 5 percent increments of colour strength. The top row handles colour temperature, from yellow through to blue purple. The bottom row handles “tint”, from magenta through to green. The middle row, goes from a red to a cyan .

To use them, simply check which square looks whitest against the background. If the background leans slightly green, for instance, a square on the magenta side will probably look closer to true white. That tells you which direction to nudge your tint control.

One last thing worth remembering: your room's ambient lighting will influence how you judge all of this. Do not calibrate for magenta while sitting in a room bathed in green light. Match your adjustments to the conditions you will normally be viewing in, and you will end up with a screen that shows your photos the way they are meant to be seen.

You should now have better screens to judge your images, that may be photographing your art, a portrait or to judge your results as you edit or modify your photographs with filters and app.

Another Microsoft favourite bites the dust

I thought I had put off any Microsoft updates for 5 weeks, but the updates happened last night. Maybe it was 5 weeks

It proudly announced that it updated itself and had five things to show me I don't think any of them were particularly new and/or exciting. They just wanted me to let them access my settings which I decided wasn't a good idea. The one thing I did immediately notice was that my phone link had a big message at the top and it wanted me to read the QR code on the screen. I had gotten used to using Phone Link and liked it.

Not unexpected, I had also updated my Android phone (I had trouble recharging my 7-year-old phone battery) and perhaps thought it was to do with a setting on the new Android phone. I did use Android Switch which worked quite well, and transferred most things. There were a few inputs required, I had to re-establish some connections with passwords etc. However the transfer was very smooth.

I aimed my camera at the QR code and clicked on the link, which took me to the site aka.ms (which is where you download the phone link segment for your phone), BUT, and it's a big but, it was a blank screen, so I tried again, investigated what response I could get, waited a while, then tried again and again. I could see from the display on my laptop it was still pointing to my old phone so I went and found it and made sure it was turned off. I went back to my phone and just typed in the address aka.ms to get to that URL. The phone seemed to think for a little while and then came up with a big red warning that my phone was not suitable because it wasn't connected to a VPN, which it isn't. The message also conveniently suggested that I could use Microsoft Azure as my VPN, and again no thank you. I don't really want Microsoft snooping on my phone as well.

If you're listening, Microsoft my trust in you is diminishing everyday
