Hello professionals

I am a manufacturer of ice cream machines, i hired a photographer who has shot my 8 different type of machines...i am not getting the pictures right..as these metallic bodies in shape of 3 dimensional squares and rectangles...are not coming really straight...it seems that some kind of ballooning/distortion/skewness has come...

i discovered it when i open the tif file in photoshop and place guides along the machine lines... i see that the machines are compressed from below...and not coming has square/rectangle...

The photographer says that this must be corrected in photoshop as it is BOUND to happen..whereas i know that we see a lot of TV/Refrigerator car advertisements.. and these products are as perfect as thier real dimensions ...

where is the problem??
is the photographer not having the proper lenses?
or do all the products need to be corrected dimensionally in photoshop?

The only way you used to get a building on a picture without having to make any corrections was with a Tilt & Shift lens, because you're looking up and therefore the lines won't be straight (vertical) and that's called perspective.

So when you take a picture from some machine with straight edges the same will happen, and luckily Photoshop can replace the Tilt & Shift lens because they are pretty expensive.

A good photographer will have those lenses, but then a good photographer will also be an expensive photographer :lol:

When the film is at a different plane than the subject, you'll get perspective control if your lens does not compensate for this. (The aforemention PC lens for 35mm cameras.)

Use of a 4 x 5 camera can also be used. Some studio photographers use this as the camera is much more versatile, and the image quality exceeds other smaller formats. It is likely that some magazine ads were produced using this camera.

While distortion can be fixed by editing, but the image may not look natural after the fix.

If you're not happy with the images, perhaps the photographer can keep the camera level with the image plane (not looking up or down at the item), or can use a 4 x 5 camera, or a PC lens.

Good luck on getting the image that suits your machines.

Since the pictures are in TIF format, I'm assuming that the photographer used digital.

Others are right - the plane of the film or sensor must be the same as the plane of the surface of the subject or a perspective distortion will result. For example, if he's looking downward at the machine when the picture is taken, the bottom will appear narrower than the top.

Two things that can help - one is to get the camera situated so that the front of the camera is parallel with the vertical surfaces of the machine. Another is to use a longer lens - something in the short-telephoto range - and stand farther away. This will tend to minimize the perspective distortion.

A tilt-shift lens is a great solution as well, but if he doesn't have one, then it isn't a solution in this case.

hello

the camera used was mamiya medium format...i heard the photographer's assistant talking about moving back and using 150mm or 200mm camera...which the photographer denied saying the picture will become "flat" as it happens more when we move away from the subject....

what is this "flat" story???

thanks for precious reply, this helps me to talk to my photographer and force him to take the right measures to get the pics right...


...some people really sucks..this guy calls himself a professioanla photographer..although i signed him seeing his job on food,pens,and other small objects....i think he hasted my shoot on these large industrial products...

anyway, assistance from friends across the golbe has proven very very helpful and encouraging..

i wanna send the file to all the member.
please give ur emails or private message me..
thanks a lot

I don't think it's smart to e-mail photos to all the members. Read this about how to post images to this forum: http://photography-on-the.net/forum/faq.php#24

"Flat" means lack of depth. When you use a telelens a picture looses depth, while with a wideangle it gains dept. But that's also a matter of changing the perspective in your picture.

Try it yourself with your digicam. Take 2 pictures of the same subject from the same distance`and aperture, one wideangle and one in the telesetting and see what happens.

Unless you have purchased the rights to these images from the photographer, be careful about posting them without permission. You may have rights that allow you to use them within a very narrow scope of purposes. The photographer may take exception to your posting them for critique or modification. If you purchased all useage rights...post away.

I think his assistant was thinking more along the lines of what you wanted.

Suppose someone is holding their hand towards the camera and you can see just a little bit of the arm. Shooting close to the subject would give them a huge hand and you can easily see the hand is much closer to the camera then the face. But being back a distance, the hand is not much larger, and you don't know if the arm is just short or what, as the image is 'flat' with no perceived 'depth.' A long lens is an easy way to be far enough back to 'flatten' an image, and still get a good image size.

You really want to preserve the geometic dimensions of the ice cream makers with as little distortion as he can get.

Quick test: Use your faces reflection in a door knob. If you get really really close your face is extremely distorted, but if you back off a few inches, it gets less distorted... The round surface will always distort the image, but you can see the property working as distortion decreases as distance increases.
