When sending plastic spool photographs to Changhui, an isolated close-up may not identify the product it belongs to. Start with an overall view that shows the structure, then add detail photographs for the areas under discussion. Use the same product or sample reference throughout so the recipient can follow an explicit connection instead of guessing from colour or appearance.
Mark the viewing direction and area of interest on the overview, and use matching area references on the detail images. Number similar-looking samples individually. Do not combine an overview of one sample with a close-up of another. If flanges, barrels or accessories are photographed separately, explain whether they belong together; leave uncertain relationships open for clarification.
For a bore, flange edge or connection, state the question the photograph is intended to address. Identify the specific location rather than simply asking for dimensions to be confirmed. Images do not replace dimensional records with units, measurement locations and sources. Perspective, camera angle and apparent scale do not establish unmeasured dimensions or equipment compatibility.
Retain original photographs and put arrows, references and explanatory text on separate working copies. Place annotations near the relevant area without hiding the detail. Identify the original behind any crop or enlargement. Record known wear, alterations and photographic conditions honestly; do not retouch a problem away and present the edited image as evidence of the original condition.
Before sending, check that filenames, the attachment list and image references agree. Distinguish reference-only photographs from documents used for the current review. List missing views for follow-up instead of inventing hidden structures. Record replies against the relevant image and revision, without extending a comment on one area into a performance conclusion for the whole spool.
Clear photo relationships support structural discussions with Changhui but do not establish model suitability, testing or purchase approval. The illustration here is a product reference, not a customer sample or an on-site incident record. Final dimensions, materials and operating conditions should return to the drawings, sample notes and other reliable information explicitly agreed by both parties.
