Ricehigh has a good method. Sadly Photobucket have messed up the photos in the article, but the text is there....

Be careful focussing at 45deg the spot focus can move about a bit. Something like this that can be folded vertical is better.

I just fold a triangular target out of A4 paper (looks like a roof) and place it on the A4 test paper then move it out of the way after I've focussed then take a shot.

The main requirement is that the target is parallel to the sensor. 45deg is also a bit too much the camera can slip so a bit flatter 35-40deg is better. I use a small adjustable angle finder (spirit level) to check they are parallel.

This is the setup with the target pushed out of the way. Squiggly pen marks help in the checking. The metal disks are magnets to hold the test paper in place on a metal table.




The Ready Brek characters card is great for manual focus because the coarse screen printing used causes moire in the viewfinder/screen.

The lens was a DA 35mm f/2.4 so big depth of field. It was also f/8 I was checking for focus shift.

Looks interesting. Pity they had to use chains.

System Mechanic Pro may do a similar job. I only ever used it on an old XP machine not on my 64bit Windows 7 machine, because it's got loads of memory. It did used to clear up a lot of memory.

The description (because it's free software) doesn't look like it's been updated, but the top details give ... Supported OS: Windows XP (SP 3), Vista, 7, 8, 8.1, 10

There's a portable version which can be tried and deleted if of no use.

Looks exactly like smell control to me!
Probably just a firmware upgrade.

I was just wondering how MS cope with Windows installs. I can buy a DVD which makes the install very simple or if I want a digital download I have to ......

"To use the media creation tool, visit the Microsoft Software Download Windows 10 page from a Windows 7, Windows 8.1 or Windows 10 device. "

So I just need another PC download and then create the install media
I should be ready to install in an hour or two

I'll ring MS and see if they can lend me another PC

Thank God for DVD Drives

Back to the Pentax software. I was going to put a mountable image of the K-1 CD on my PC so it was readily available, but it's an older version than the latest download so anyone who has just bought a K-1 needs to update

I'll have to inject the update into the CD image or just make an image using the download files. Saves messing with an SD Card.

For pixel-shift Raw Therapee is supposed to be the best at present.

There is a lighter version of Silkypix available online for £52 but if you have a Pentax you are eligible for a discount of NOTHING

Would it not be easier to just learn how to use Google

Canon used to be the same as Pentax and a hack was needed if you had an incomplete PC. Instructions 19th Oct. 2017 from Northlight not supplied by Canon
http://www.northlight-images.co.uk/install-canon-camera-software-without-cd/

They have recently started to suppy a download version and you need to enter the camera serial to get it (or know how to use Google )

Pentax might not be able to do this because of theirs being a cut-down Silkypix. The workaround is so simple it really doesn't matter

The full version of Nikon software costs £213 I don't know how it's maintained because it was written by NIK
