Hi,

Im doing a photo shoot of various bottles my company makes, we are getting
great results for solid colored bottles inside our light tent. but the
minute we try shooting clear bottles we are getting very poor results (poor
focus, faded bg). can you give me some tips on how to shoot clear bottles?

thanks

Light the background, not the bottle.

After focusing on a solid colored bottle, lock the focus point and
replace the bottle with a clear one. Depending on the camera, you
may have to switch from AF to Manual focus mode to allow multiple
shots without having to refocus. I'm not sure what you mean by
"faded bg", but if you're talking about the background's lightness
or darkness, check the shutter speeds and apertures used for the
solid colored and clear bottles. Different exposure values may have
caused different apertures to be used, and then the mix of ambient
light and light from the flash may have caused the problem. For
instance, if a mode is used that sets a fixed shutter speed such as
1/250 due to the flash being used, if a clear bottle appeared
"brighter", the metering system would cause the camera to use a
smaller aperture. This would make the background darker (faded?),
since the illumination contributed by the more distant flash might
be minimal. But the flash would fill in whatever was needed for a
proper exposure of the bottle.

Use a polarizing filter. Linear or Circular, both will works for what
you want. Focus on the bottle then switch the button to manual focus and
adjust the polarizing filter for the desired effect.
tip: when auto focusing, use the central point, partial metering and
focus on a ligth reflexion on first surface of the bottle.

Are you using flash???? If yes, forget this sugestion.... this is for
non flash shot.

Change the white balance from 5500k to (for example) 3300k and when you
do the RAW development, change it back to 5500. This way you will obtain
a "coloured" bottle which you can turn back to it's original colour and
the background -which you used 5500k lights to produce, will disappear.

Hi.

I remember this subject came up during a lecture being given by a Pro.
Photographer.

He was able to put up some slides of Glassware which looked very good. He
then explained that he had needed to use a number of "Shaped Gobos" in
order to produce shadows on the bottles, which demonstrated their roundness.
Cutting out and placing these Gobos took the major part of the time
allocated to the shoot.

The general conclusion seemed to be that to produce a picture which made a
clear glass bottle look clean and the glass flawless, yet showed up its
shape, was one of the hardest things to do in a studio.

I have to say that this guy specialised in "Product" shots, which included
Motor Cars, and had a custom built studio the size of a small warehouse.

It depends on what you want to accomplish. You can sidelight
the bottles against a dark background (shape defined by highlights) or
backlit (shape defined by lowlights) or any number of other means.
Take a decent photography class and you'll be shown various methods.

Similar comments also apply to photographing silverware, etc.
where keeping camera reflections out of the shot is an additional
consideration.

I took a product shot lighting seminar year ago. (My project included
a wine bottle and a wine glass, filled. Three separate exposures to
make one photo on one film in a 4x5 camera.)

The idea for clear glass is to shoot in a darkened room or use 'flags'
to create areas of black (absence of reflections) seen in the glass,
and to also use panels (or softboxes with a suitable mask over the
front panel) to provide white shapes reflected in the glass to provide
form. Then hit the backdrop with light separately. The lit backdrop
provides the basic 'canvas', the black areas seen in the glass provide
the basic 2D form with definition and contrast against the backlit
'canvas', the reflections of white panels or softbox provide the 3D
form. Think of this...you see THROUGH glass, you see REFLECTIONS in
the glass to give your brain clues about the shape.

Even for colored glass, the reflections provide more 3D form to any
shape you light.

Set up the shot, then put a spot light at the camera position. move
around looking at the bottle until you get a `nice' outline effect
from the light. remembering that it is not quite an exact copy of the
final effect. Now put the light at your view point and check from the
camera position. Fine adjust and shoot. You can also use coloured
lights for more effect.
