I'm having some ideas for macro/product photography shots that have to do with my day job (dentist) and I was wondering how I managed best the isolation.
I would like these shots to be accepted at SS as well.

I know how to work the PS Pen-Tool but I can also manage a decent white background using a white underground from vinyl that was not really cheap and that I can still return.

Using the background I can manage a relatively white background around RGB 230, and I can save myself the PS troubles, but I cannot guarantee 255 in all places.

I have seen some shots on SS with a perfectly white BG in all places, but others do have a little greyish tint here and there just like mine.

So my question is, do I use that pricey background, or will I have to cut out everything anyway with the consequence that it doesn't really matter what background I use?

Thanks for your input!

Best Regards

you can cutout and isolate object from background in any condition, on white black background its more easy that way you don't have diffrent color or light reflect on the item edges

for example you have a bottle in a resturant u have reflection on the bottle from the space, on white background you eliminate most of the reflection and color cast on the item

That thread is related to my question, does not however answer it.


Do you advise, for best sales and acceptance rate, to cut out any and every picture you'd place on a white background, or do you prefer the natural look of the small remaining greyish tints, not just in the shadow areas but also in the corners etc. (Nothing dramatic, but never as white as completely RGB 255, cut out)

If you  leave any  grayish on the white you fail the inspection! Especially the corners.

Ah thats what I was wondering, because I saw a lot of pictures that do not meet that criteria 100% either and wondered how they got accepted.

Can I manage 100% white with a better light setup or will I always have to do some photoshopping?

the background helps, but it need not be expensive. You can use anything white.

and...
the clean isolations are done in photoshop more than in the camera.

I find that using a mixture of both helps. I use Photoshop to make the background whiter by masking the subject and pushing up the exposure of the background. Having a good clean white background to begin with helps the workflow a lot. By feathering the mask it is a lot easier to do than cutting out a subject on an unsuitable background.
