The following tips are mostly related to architectural visualisation.
Once satisfied, simply press “Enter” to Crop extend the document/canvas.
In addition, create a new layer( Ctrl+Shift+Alt+N), fill the selection with the Paint Bucket tool(G) and save the document as a PSD file.
This action is necessary to ennsure Photoshop "hides" the the extended area after Cropping it. Otherwise it will assume that, the extended area is empty without pixels/layers and subsequently delete/crop it...as opposed to hide it.
In such cases, the scale discrepancy is usually by a factor of 1.0.
Erasing/masking out pixels behind tree leaves/branches for Photomontages
Until recently, undertaking the laborious task of erasing pixels behind tree leaves and branches could be considered to be any visualiser's nightmare.
For those who still do it the old fashion/tedious way, the following technique will definitely help speed up your workflow dramatically:
Without further ado, let's start by first duplicating the layer you'll be working on(Ctrl+J)
To help highlight the effect of this excellent Photoshop tool, we are going to use a red layer underneath the working document (i.e. underneath Layer 1).
To do so, create a new layer below the duplicated layer, and fill it out with the Paint Bucket tool.
To begin erasing the pixels behind the tree, simply go to the side tools and pick the Background Eraser Tool.
Also, choose the Sampling Once method and set the tolerance value to about 52%.
This value is a good starting point to target specific areas accurately. However, feel free to experiment with different values, if desired.
To customize the brush size and its softness/hardness, simply click on the Brush button, from the main toolbar and slide the relevant slider to either direction.
Prior to begin erasing pixels, first select the working document (i.e. Layer 1).
Next, target the pixel colour with a left click, and hold it down thereafter.
While holding down the left click, begin brushing away.
To re-target new pixel areas, simply release holding down the left click, and left click on new pixel area, as previously done.
I hope you have found the tips somehow useful!
