I'O Studio is a premium photography studio with three locations in Seoul (Sinsa, Gangnam, Hongdae), offering ID photos, semi-profile, and full profile sessions. Instead of exaggerated staging, we work with restrained light and composition to create records you will keep returning to.
High sensory Archive studio — what I'O pursues is not just one good-looking photo, but an accurate archive of who you are right now. From shooting to retouching, a dedicated photographer works around your tone and mood.

What's the difference between semi-profile and the profile packages?+
Semi-profile is a quick session (about 25 minutes including selection) where you receive one retouched photo on the same day. The profile packages (1–3 concepts) include a longer session, your own photo selection, 2–9 retouched photos, and all original files — the 2-concept package takes about 2 hours in total including preparation and the concept meeting. Framed prints are included with the 2- and 3-concept packages. See the booking page for current prices.
Is hair and makeup included?+
Hair and makeup is not included by default. You can add it as an option while booking, or use one of our partner salons at a discounted rate. See the hair & makeup page for details.
When do I receive my retouched photos?+
For semi-profile and ID photo sessions, you receive the retouched photo on the same day. For profile packages, after you select your photos and submit the retouch request form via the Google Drive link we send, retouched photos are delivered within 3 business days.
Do I get the original files?+
Profile packages (1–3 concepts) include all original files, delivered by email between the shoot day and the next day. For semi-profile and ID photo sessions, originals are available as a paid add-on. Originals are kept for up to 6 months from the shoot date.
How do I check availability for a specific date?+
Choose a studio and date on the booking page at iostudio.kr — the open time slots you see are live availability.
Can two or more people shoot together?+
We offer a 2-person semi-profile package (both of you in one frame). If each person wants their own session, book separate time slots — Gangnam runs two separate shooting spaces (up to two parties per slot), while Sinsa and Hongdae serve one party per slot. For groups of three or more, contact us via chat for a quote.
Can I rent outfits?+
Basic outfits are available to borrow for free at every studio (chosen on site, mostly size 55/M). There is no online catalog, so if you have a specific look in mind we recommend bringing your own.
Do you take ID and passport photos?+
ID photos are available at our Gangnam and Hongdae studios, with a passport-format option using the same shot. You leave with the retouched file and printed copies the same day.
How are the three studios different?+
Hongdae works with all-day natural light in a 7-meter-high space for a soft, dreamy tone; Gangnam builds precise studio lighting around each face. Sinsa is dedicated to the 1-concept profile package. ID and semi-profile sessions run at Gangnam and Hongdae.
Can I order extra prints or frames?+
Prints for semi-profile and ID photo sessions are handed to you on site the same day. For profile packages, the included prints ship once your retouching is finalized (free domestic shipping); extra items are available — A4 frame 40,000 KRW, acrylic frame 15,000 KRW, paper frame 7,000 KRW (shipping extra), additional prints 10,000 KRW each.
How do I change or cancel a booking?+
Look up your booking at iostudio.kr/lookup to change or cancel it yourself. Date changes are possible up to 10 days before your session; refunds follow the schedule on our refund policy page.
Is parking available?+
Gangnam has building parking (public lots nearby when full) and Hongdae has paid building parking. Sinsa has no dedicated parking — please use nearby public lots. All studios are a short walk from the subway, so public transit is recommended.
Can foreign visitors book and pay?+
Yes. iostudio.kr is available in English, Chinese, and Japanese, and accepts overseas cards, PayPal, and WeChat Pay (on the Chinese page). No Korean phone number is required.
