We delved deeper into Photoshop today. I showed Simon an image I took in the underground station (pic1) and he explained to us the dos and don'ts when taking a nice photo for texturing. I could get better results if I stood back and zoomed into the image which results in a less distorted image. There are tools in Photoshop that can be used to edit the image and to straighten out the distortions. I was introduced to the lens correction tool which allows me to state the lens of the camera used and remove the lens distortion, or alternatively use the custom options it provides to manually re-adjust it to my liking. The second image was the end result of this, I managed to remove the slight perspective and flattened it out so I could use this as a tiling texture.
Next we looked into ways to edit an image. One thing to avoid when creating a tiling texture is any bold areas which won't look good when repeated, this can be crevices, stains and objects. -These can later be added on as an overlay/decal. Using an image, we used different tools to edit it and make it into a tiling texture. Simon showed us the healing brushes, patch tools and content aware to 'magically' remove aspects of the image. It was great to see its effects and really shows how much flexibility I have when editing an image.
