Basic photo watermarking on an iPhone

If you happen to take images of ‘stuff happening’ that might be newsworthy and that you want to share but not have mis-used there are apps that let you add a watermarks. I presume these watermarks can also be removed later, presumably by you (but perhaps by newspapers) so I might suggest screenshotting the image first and sharing that instead. Screenshotting also means minimal EXIF data. But you can do it without apps too and just draw your initials on the picture and only remove them when you send (by DM) a copy of the image to media sites you want to [though this won’t stop someone from passing it on I suppose…].

For iPhone users you can draw on any picture in the Camera roll –

  1. Make a duplicate copy of the photo first (to keep the original safe)
  2. Draw your watermark on the copy
  3. Screenshot the watermarked copy and share that (watermark possibly harder to remove because it’s no longer layered on top of the image, and EXIF data is hidden)
  4. Resizing the image if necessary

1. Duplicate the original

Have the photo open, click the upload icon (the one on the left in the all-blue icons picture below), then choose Duplicate which is the middle grey icon in the second image below. Note that you may have to scroll right to find this option.

Pic 2. Duplicate icon is a grey rectangle with a white + & a single grey rectangle behind.

Once you’ve created your duplicate open that one (you can slide back and forth between the two copies).

2. Draw your watermark

Click on the Edit option (on the right in the pic below), then choose the three overflow dots in a circle (•••), then click Markup.

You’ll have the option of various pen thicknesses, and colours to choose from. To select the colours click on the (()) symbol…

…or you can add text by clicking on the (+) at the end (in pic above).

Once you’ve added whatever watermark format you’ve chosen and clicked DONE twice (once in blue at the top right of the photo, and once in yellow at the bottom right) you’ve completed the ‘add watermark’ to your duplicate image bit of the process.

3. Screenshot it

Click on the image to remove the white borders (the bits saying the current date / time, battery info or whatever’s currently on your phone) and to see the image just on its own – usually with a black border at top and bottom. The two images in 3A below are identical, the only difference is the white or black border – this is a toggle-click, where clicking once hides the phone info and clicking again brings it back, and so on.

3A

Press the ON/OFF button and HOME button simultaneously (iPhone) to make a screenshot which is saved to your cameraroll. (You can do the white-border one too of course but may need to do an extra step of pruning out the additional info)

This is the image that you should share.

4. Resizing / removing the white or black borders

If you want to prune out the borders outside the relevant image, or only want to share a particular portion of the image then use the cropping tool to do this.

Click the image again to bring up the white borders which shows the options. Click Edit (see 2A), then the white square tool from 2B which will go white as shown at the bottom of the three images in the panel below.

Left: the square button brings up the resizing boundary – you can use the corners or sides to shrink the picture. Middle – I’ve taken most of the top black border off and the resulting image now takes up more space on the screen. Right – I’ve pruned out all of the unnecessary bits. The next thing I click on is Done (in yellow, bottom right of each pic).

 

How to tweak (digitise) drawings in Inkscape

I’ve been playing with Inkscape, a free open-source image processing tool. For a project I need to draw some cartoonish images and clean them up and I’m learning how to do that thanks to YouTube and Inkscape’s own tutorials.

Note: If you’re using Inkscape on a Mac you may also need to download XQuartz; note that you use the Ctrl key not the Command key in Inkscape. Similar software is Gimp (free) and Adobe Photoshop (not free). I’m also teaching myself to use Scribus, a layout tool, but I mostly use PowerPoint for that at the moment.

Here’s a drawing of a house (biro on white paper) photographed by my iPhone and emailed to myself. Scanning it in would give a much better starting image to work with and drawing it more neatly etc etc but I’m just playing for now.

Imported into Inkscape by File > Import and OK-ing whatever suggestion it gives

Once imported ensure it’s selected (click on it if not) and that the arrows are double-headed, then choose Path > Trace Bitmap

Fiddling about with the settings … (use Update to see how it’s going before using OK to apply)…

…produces a layer which can be moved away from the main image, resulting in a separate clean black and white image.

 

The resulting image…

Further tweaking can be done by using the node tool (looks a bit like an archer’s bow between the pointer icon and wave (?) icon in the panel on the left below) and moving the lines about but I’ve not bothered with that for now.

OK I had a bit of a play around with it. Stretched the E.  (Eeeeee !)

Things I’ve learned after a few hours’ play

I have not been saving images as .svg files (which is, I think, what I am supposed to do) and am. just cheating, copying a screenshot and pasting into my .pptx presentation. I’ve noticed that enlarging the image once in the PowerPoint neans that it looks a bit grainy so I recommend enlarging it in Inkscape by zooming in, taking a screenshot of that and then it will look better.

I’ve also had some fun with the ‘bucket’ tool which fills an area with colour. Also the resizing tool (hold the Ctrl key [Mac users you too, not Command] to enlarge or shrink while keeping the same aspect ratio.
