Explanation of the Reflector card with lens hole:

The glass and bottle are both mirror surfaces that sharply reflect whatever is around them.

If you use reflector card(s) to the side of the lens, the center of the label will be dark.
The lens-hole leaves a small round dark spot reflection that is much easier to hide or retouch.

For a setup like this, I would use a full sheet of mat board (32"x40") curved into a horizontal arc, and place it off-center enough to provide some asymmetry to the reflection, then cut a hole just large enough for your lens hood.

Try it again, and let us see the results. A nice thing about this type of work, is that redo's are easy, and every time you reshoot, the results improve.

The wine and the bottle both look totally opaque, because there is no light coming from behind.
Remove the background card, replace it with a large softlight a couple of feet farther back. Then cut a piece of that background to a size just large enough to fill the frame. the light coming from around the sides and top of the background will put some light through the wine and bottle. A large white reflector card with a hole for the lens will light the front. Front light can be increased by pointing another light at the reflector card, making sure to not let it reflect in the subject.

I think the arrangement of the objects is rather static. Three rows of two items each, lined up perpendicular to the camera - boring.
Try moving the glass forward and and slightly to the right, so that it covers part of the bottle, without obscuring the label. Opener and cork together on the right, grapes & cheese on the left, all items diagonally arranged, slightly overlapping each other.
I would light the scene with a large soft light from above and behind the subject, and reflect light with a large white card in front with a hole for the camera lens. The reflector should be wide enough to light the important part of the label, narrower on the right side of the lens to lend a little asymmetry to the lighting. Retouch the lens reflection in PP.

For top quality, you will probably need to print your own. Epson photo printers have the ability to accept 16 bit data. And you can use ProPhoto color space for the largest possible range of color. BTW, inkjets don't print CMYK anymore, they have lots more colors than that.

Feel stupid asking this . Is there any formula that can be applied to determine an optimum focal length for a lens when the size of the object and distance to the object are known and the intention is to fill the frame on say a full frame sensor.

Lay in, I can take it.


Here's a handy online calculator info & link:

Dimensional Field of View Calculator
This calculator computes the field of view, measured in feet or meters, for a lens of a specified focal length on a 35mm camera. For most modern consumer level digital SLR cameras, a focal length multiplier of greater than 1 is appropriate because these cameras have a smaller sensor than a 35mm negative. For these cameras a focal length multiplier of approximately 1.5-1.6 is appropriate. Note: This calculator assumes a standard width/height image ratio of 3:2.
Distance Units:

Lens focal length (mm): FOV (horizontal) (feet/meters):
Focal length multiplier: FOV (vertical) (feet/meters):
Distance to Subject: FOV (diagonal) (feet/meters):

What am I missing in the "follow the bird in flight?" Doesn't the red dot need a nearby background to reflect off of to adjust the aim onto the flying bird? If one could put the red dot directly on the bird instantly, why would you need it?

No it does not project a dot onto the subject like a laser does. It's a large window, optical viewfinder, with a moderately wide field of view. The dot is projected onto the viewfinder lens. I'm sure there are U Tube videos showing it in use.

Try one, and you will buy it. It's only $140 or so. The Olympus Dot Sight weighs near nothing compared to the camera and lens, and eliminates losing the bird in the viewfinder.

Almost 100% keep rate for BIF? What do the ten frames on either side of that shot look like, keeper rate wise.

It is a gadget that folks who like gadgets buy. It is not necessary for bird photography.


Says the guy who has not tried one on a long lens camera, shooting birds in flight!

Thanks Dik, looks like it might be an inexpensive option to try and if it doesn't work for me, at least I'll have new reflex sight...


Here's my Conowingo setup. Counterbalanced boom with gimbal head mounted on tripod chair.

Olympus dot sight on 5DIV, 100-400 + 1.4. Works so good that last time I went to Conowingo and discovered I’d left it home, I gave up shooting without it, and returned home.

nicely done too, fascinating stuff, been around for millennia, a lovely gift mother nature provided for old and creaky humans, my pop at 90 who was a opponent for most of his life is now enjoying the results provided, he has seen the light............


Thanks.

How about a wide gamut?
