When sorting through this set of Fate/Grand Order Eresh and Ishtar Swimsuit cosplay photos, four years had already passed since I first conceived this project. Although shot last year, post-processing dragged on until this year to finish the Eresh set, but the moment it was completed, the wait felt entirely worthwhile. The workload for this seaside shoot was actually massive. Take the shot on the white lounge chair: the shooting angle was tilted slightly downward. To showcase the sheer, skin-revealing texture of the red Stockings along with sleek leg lines in that posture, it relied entirely on core strength. The thighs had to stay tightly engaged, which, paired with slightly closed eyes and sunglasses, truly captured a cool, aloof, and languid aura. The lower half of the set featuring the frontal standing pose mainly tested keeping the chest lifted and core tucked while managing the hair in hand; the facial expression also needed to strike a just-right backward glance, placing high demands on expression control. In the second series holding the floating mat by the sea, the waves were crashing in rapidly. The photographer lowered the camera angle extremely close to the ground, using a tilted composition to capture dynamic energy. While it looks like a candid snapshot, we actually rehearsed nearly ten times to freeze that exact instant and wave position. The overall retouching logic for this set was unified: the most common issue under the blazing seaside sun is blown-out highlights, especially water reflections turning into stark, dead white patches. Therefore, we focused on bringing out the tonal layers of the blue sea and the shadow details of the red clothing, utilizing local masks to suppress highlights while preserving healthy skin tones and lip luster. Regarding color grading, Eresh's outfit is dominated by pink and orange, edited to lean toward a warm summer sunshine texture, whereas Ishtar's set is white and blue, preserved to maintain a crisp, cool transparency—creating a striking color contrast between the two. The swimsuit, cage prop, and floating mat used in this shoot all served their purposes wonderfully; incorporating props into poses added great three-dimensionality to the visuals. Although a long time has elapsed, sometimes setting the raw photos aside before retouching allows for a more mature understanding of light, shadow, and color, commemorating those seaside moments through a more composed and seasoned lens.
