By E J Spode – We need to talk about trust and its place in the fabric of our lives. Trust seems to be in short supply these days, although we have no choice but to rely on it.
We trust schools and babysitters to look after our children. We trust banks to hold our money and to transfer it safely for us. We trust insurance companies to pay us should we meet with some disaster. When we make a large purchase – such as a house – we trust our solicitors or an escrow company to hold the funds until the transaction is complete. We trust regulators and governments to make sure these institutions are doing what they are supposed to be doing.
A good way to wrap our minds around ‘blockchain’ concept is to think of its most famous application: Bitcoin. And the best way to think about Bitcoin is not in terms of coins at all but rather as a giant ledger.
Bitcoin is just one version of the blockchain. The fundamental technology has the potential to replace a much wider range of human institutions in which we use trust to reach a consensus about a state of affairs. It could provide a definitive record for property transfers, from diamonds to Porsches to original Picassos. It could be used to record contracts, to certify the authenticity of valuable goods, or to securely store your health records (and keep track of anyone who’s ever accessed them).
But there’s a catch: what about the faithful ‘execution’ of a contract? Doesn’t that require trust as well?
What good is an agr’ement, after all, if the text is there but people don’t respect it, and don’t follow through on their obligations? more> https://goo.gl/rW7huO

How to Create a Surreal Photo Collage
By Terri Stone – When you composite photos, you usually don’t want the result to look like a composite. Even if the final scene is fantastical, your aim is to transport viewers into another world. Filip Hodas, a 24-year-old freelance artist from Prague, has been creating convincing digital realities for years. Now he’’ agreed to share his process.
To make the otherworldly landscape featured here, Hodas relied heavily on Adobe Photoshop CC layer masks. He placed each source image on its own layer and then used layer masks to hide and reveal parts of each. He also used layer masks to adjust color and add highlights and shadows.
Next came a Color Balance adjustment layer, which he added to the background images so their colors would be a better match. Trees on the right side of the horizon image were distracting, so he removed them with the Clone Stamp tool.
Hodas knows that small details can have a big impact on a composite’s overall look, so his next step was to refine the foreground image’s mask. That softened jagged edges a little and removed a slight yellow outline. more> https://goo.gl/7jat2c
