fixed : quickly create a printable grayscale picture from a color photo using Preview.app

Question :

I often have color pictures (like photos) that I would like to print in grayscale, but I don’t have a grayscale printer.

What is the simplest way to do so ?

 

Answer :

Having a color printer is great, and the easiest way to print grayscale pictures is to just select the grayscale-option before printing :

  • open the picture (ussually a .jpg) in Preview.app
  • in the top-bar, go to File and select Print from the pulldown list ; or press the [CMD]+[P] key-combo on your keyboard
  • in the pulldown window that opens, click on Preview and select Graphics from the pulldown menu
  • then, at Color Mode, select “Grayscale” (instead of “Color”)
  • then click the Print-button and see what comes out of your printer
  • Note that if you would make a PDF now, that it’s not going to be a grayscale picture…

Sometimes this will do just fine, but often that isn’t enough, and you will need to do a few extra steps to get an acceptable result out of your printer :

  • open the picture (usually a .jpg) in Preview.app
  • click on the “Show Markup toolbar”-button (the circle with the pen-point in it, just left of the Search-bar top-right)
  • first, crop the image if needed :
    • then, click on the DashedSquare-icon (top-left) and select the “Rectangular Selection” option
    • on the picture, select the area you want to use (click the top-left of the envisioned area, than botom-right) and the selection area will be displayed
    • if you need to, adjust the selection area by dragging it’s edges
    • then, in the top-bar, go to Tools and select Crop from the pulldown list ; or type the [CMD]+[K] key-combo on your keyboard
    • now the picture will be croped to the smaller ‘selection only’ size
  • then, in the top-bar, go to Tools and select Adjust Color from the pulldown list ; or type the [CMD]+[ALT]+[C] key combo on your keyboard
  • in the AdjusColor-window that opens there is a ‘histogram’ (a picture with red/green/blue (a.k.a. RGB) graphs) with an AutoLevels-button, a list of 9 sliders and a ResetAll-button below it
  • attached to the base of the histogram, there are 3 slider-pointers (a.k.a. histogram-sliders)
  • set the middle histogram-slider lower (a little to the left)
  • then set the right histogram-slider lower (a little to the left)
  • then set the Exposure-slider higher (a little to the right)
  • set the Contrast-slider higher (a little to the right)
  • set the Sepia-slider in the middle
  • set the Sharpness-slider higher (a little to the right)
  • see if the (color) picture’s look is now clearer …if not go back and adjust the sliders until it is a brighter picture with more detail
  • then, in the top-bar, go to File and select Print from the pulldown list ; or press the [CMD]+[P] key-combo on your keyboard
  • in the pulldown window that opens, click on Preview and select Graphics from the pulldown menu
  • then, at Color Mode, select “Grayscale” (instead of “Color”)
  • then click the Print-button

that’s it !

Note : if you would make a PDF now, that it’s going to be a color-picture, not a grayscale picture… if you need a grayscale picture digitally, you will need to use Photoshop  or something similar…

Important extra note : once the picture is a PDF, you can no longer adjust the colors

enjoy 😉

fixed : need to close Google Doc to prevent further adjustments

Question :

We have been working on an online Google Doc with several people and since we have reached the final version, I want to prevent anyone from making adjustments to the final version.

How do I do that ?

 

Answer :

If you want to close a Google Doc (or Google Sheet or Google Slide) to prevent additional editing, you should change the sharing setting of the Google Doc (or Google Sheet or Google Slide). Here’s how to :

  • go to http://docs.google.com and login
  • find the Google Doc (or Google Sheet or Google Slide) that you want to close ; select it from the list of documents
  • open the document
  • click the SHARE-button (the blue button, top-right)
  • then adjust the sharing from “anyone with the link can edit” to “anyone with the link can view” (or “anyone with a link can comment” if you still want people to be able to comment without actually editing the document)
  • Note : if you click the white Advanced-button, you will also get the options to “Prevent editors from changing access and adding new people” or “Disable options to download, print, and copy for commenters and viewers”
  • then, click the blue Done-button to fix your new sharing-setting
  • to check if your document’s sharing-setting is correct, hover your mouse-pointer over the blue SHARE-button and you will see the current sharing-setting

…that’s it !

fixed : feeling of writing on paper for iPad Pro

Question :

I recently overheard a designer talking enthusiastically about a screen protector or something he had on is iPad Pro, which gave him the feeling as if he was writing on traditional paper when he was actually using his Apple Pencil on his iPad Pro.

Can you tell me what he was talking about ?

 

Answer :

He was probably talking about one of these two :

Paper Feel (by Geevon) get it at Amazon.com

PaperLike (by Sapper) get it at Amazon.co.uk or Amazon.de

Paper-Like (by ClearView) get it at Amazon.com

…and don’t forget to select the right size for your iPad Pro ; they’re available in 9.7″, 10.5″ and 12.9″

fixed : export eMail message as EML file

Question :

I had a complaint about the amount of spam I was getting from one particular sender, so our system administrator asked me to send him samples of the eMails in EML-format so he can have a look into the eMail-headers and adjust the spam-filter.

But how do I export eMail messages as EML-files ?

 

Answer :

EML is short for eMail ; an .eml-file is the typical way for macOS (and MacOSX) to store individual eMails that are not in your mailboxes.

The easiest way to export an eMail message from Mail.app to an EML-file is to Drag&Drop :

  • in Mail.app, select the one eMail that you would like to export
  • click on the eMail and drag it out of your Mail.app onto your Desktop (simply put : “Drag&Drop”)
  • now, on your Desktop, the eMail will be automatically be saved as an EML-file
  • you can double check this by right-clicking on the eMail-file on the Desktop and choosing Get Info ; at ‘Kind:’ it will be listed as ‘Email message’, and at ‘Name & Extension:’ it will be listed with the ‘.eml’-file extension if you uncheck “Hide Extension”

Then you can share the eMail as an attachment in another eMail or put it on a USB-stick or upload it to your system administrator or whatever you like.

That’s it 😉

fixed : weeks not starting on Mondays in iOS 11 Calendar

Question :

I just upgraded to iOS 11 and I’m very happy with this new version of iOS, but when I opened the Calendar app and went into Month-view I noticed that all weeks now start on Sundays, which I find very confusing.

I can remember that I was able to choose on what weekday my weeks should start, but I have set that long ago in some previous version of iOS to never be bothered with it again.

But now it’s been reset to the (American ?) weeks starting ons Sundays, which is very annoying as we (Europeans) tend to start new weeks on Mondays…

…where has the option to customize this gone ?

 

Answer :

This is very simple to fix, you just need to know where to find it :

  • open the Settings app on your iOS 11 iPhone or iPad
  • then goto Calendar
  • then on the next page you can adjust the settings of your Calendar, and adjust it according to your preference
  • then click on “Start Week On” and choose “Monday” from the list

That’s it 😉

enjoy !
