I would like to share with non pros, people like me, who don't own a photographic studio neither expensive lights and spotlights and just have their home lights (like me ^^)
Well, I always try to shoot in natural daylight, I often go to the balcony, I put a white background and set my mini homemade studio, specially on a bright day, without direct sun light
I try to shoot at a non very fast speed. And always in RAW mode
Once the pictures taked, here come the hard work!
I open the raws with PS 4 and adjust the exposition and brightness, then save to TIFF.
Open the TIFF files and check the background, if it isn't pure white still, I need to adjust the levels by moving the center item to the right, try not to loss details of the image
One tool I use to ckeck the white of the background (My monitor isn't very well callibrated and while I see pure white other can see artifacts left or only a whittish gray) is the next:
In photoshop, on the panel where you have all your layers, create a new layer trhough layers/new adjustment layer/Levels and on that layer put the slider completely to the right
You can see the dark areas on your image and make the pure white.
Another tool I use is the pen tool, but you need a bit of knowledge about bezier curves. I trace the silhouette of the object with the pen and then I save it as a clipping path. I select the path and delete the background
Don't use the magic wand, it created an irregular awful borders
I hope being useful for newbies and non-pros :) this is all I have learned during this 3 years in microstock
Some of my old files have an awful background I would like to resubmit in pure white, like these:
--> level 2 wuith 5 dl, wow, I don't want to disable it!! I wish I could just replace the file itself without changing the level!
--> grey BG, I would change it by now
--> tried once to re upload in white but it was refused :(
