FOCUS STACKING – the maximization of depth of field in a digital way.

Sometimes getting the depth of field on the WHOLE object that interested me is impossible – it worth remembering that laws of physics are infallible. Setting a high aperture, e.g. 32, enhance the depth, but the diffraction effect spoils the quality of the whole image (read about diffraction). However, you have to do it…

Have you ever heard about the focus stacking? In a nutshell: I make some pictures by setting focus on different areas of the object. Then I link them in the graphics program in order to make the final photograph with a perfect sharpness in all parts of the frame.

Picture in MODE Composer; step by step:

-> Connect the camera to the computer and launch the application MODEVid

-> Choose the best resolution and image quality (crucial step in the digital processing)

-> Set the proper illumination, frame and exposure. Keep in mind – the lower is the aperture; the better is the quality of the image (in this case 8-11 is good enough)

-> Turn off the AF.

->Choose the icon of Super stacking in MODEVID

-> Adjust focus manually on the nearest point of your product and press „point A“ (become green). Then localize the furthest part of product and press Icon till it will be as sharp as possible. Click „point B“.

-> Choose how many images You want to take for fully focused product

(more advance tips and tricks about deep of field and right amount of shots? – available soon)

-> Make sure that the camera is stably mounted on the Composer rails. Remember enlarge the image to adjust the value of focus more precisely. In the end use your mouse to activate fully automatic process of takeing pictures (play), do not move it during the shooting and making series. The larger zoom/macro in you use, the more reps in series you must do.

-> Final photos are collected on the hard disk drive. The focus area appeared in another area on each photo.
Let’s see on the sample – a ring:

Now, having this source material MODEVID allows working based on the mechanism of layers and automatically merge the sharpest parts of images. The final image has a perfect sharpness on the whole parts of jewellery notwithstanding the angle at what the picture was taken without any postproduction.

Hard to belive that before I made it manually!
