A focus-stacked photograph is a different kind of project record from a single exposure. The OM SYSTEM TG-7 manual says its stacking function records the first frame and a composite image. That distinction is useful when photographing details of an ordinary hobby object: the resulting diary should say which kind of image is being shown. This guide reads the English owner PDF checked on 3 October 2026, with no hands-on capture or image-quality test.

Decide what the caption must explain

If a picture is used to document a small model or a decorative feature, write a caption that identifies the subject and the way the image was made. A composite should not be described as a single unmodified exposure. This does not make it less useful as a hobby image; it makes the record more understandable to someone who was not present.

The TG-7 manual distinguishes focus stacking from focus bracketing. In stacking, selected images are combined and the first frame is recorded separately. The first shot is not included in the combined set described by the stacking settings. Bracketing instead produces a series with focus shifted between images. Keep those documented roles separate when planning the output.

Do not count the final files as the whole capture process

The two recorded pictures mentioned for stacking should not be treated as proof that only two shots were taken. A processing workflow and its delivered files can have different counts. For a project diary, record the chosen mode and the intended output rather than deriving the capture sequence from a folder containing a first frame and a composite.

When you eventually have actual files, preserve their identities before making copies for a blog or print. A cropped or resized copy can be clearly labelled as a presentation version. The source manual does not establish what a particular file in your collection contains, so confirm that connection from the actual session rather than from a similar filename.

Leave room for a failed or unsuitable result

The manual warns that camera shaking can sometimes prevent creation of a composite. That boundary belongs in the expectation for the task. Do not promise a successful stacked photograph of every subject simply because the function is documented. Hobbies Mate has not measured success rates or evaluated a particular setup.

Even a successful composite does not authenticate a collectible, identify an unknown material or prove the original object had every visible detail in one plane. The image is a representation made for your project. Questions about an important or vulnerable object’s handling require separate competent advice before photography takes place.

A clearer hobby workflow

Write the TG-7 identity, intended mode, object reference and planned caption in the project note. Consult the complete manufacturer instructions for operation; this article does not prescribe physical setup, hazardous outdoor use or an exposure recipe. After a real session, add what was actually produced and which file you chose to present.

The result is a diary that distinguishes a first frame, a sequence and a composite without claiming they are interchangeable. Keep the PDF revision and checked date with the equipment note. No performance score, guaranteed sharpness or field experience is implied. Transparent labelling lets the creative use of processing coexist with an honest collection record.
