Turn your iPhone or iPad into a tether for your camera. CloudTether connects over a USB cable or Wi-Fi, catches every shot the moment you take it, and sends the full-resolution file where it needs to go in seconds — your cloud services, or just this phone. No laptop, no card reader, no desktop tethering software. CHOOSE WHERE SHOTS GO When a camera connects, choose where its shots go: to your services (Dropbox, Drive, ShootProof and more) or to this phone only. Each camera remembers its destinations, so next time it's one tap. Shoot first, decide later: anything taken before you choose waits in Not sent yet, ready to send anytime. SEND ONLY YOUR PICKS Rate shots on the camera and only the ones with enough stars are sent: choose 1 to 5 stars for each shoot. Unrated shots stay on the card. Available for Canon and Nikon cameras. EVERY SHOOT, ACCOUNTED FOR • History lists each shoot as a receipt: when, how many photos, where they went, and thumbnails you can tap for a sharp, zoomable preview. • Not sent yet shows exactly which shots have no copy outside the app. • Shoots sync to every device and the web dashboard. • CloudTether relays each shot to your services; it isn't long-term storage. Originals are kept for 14 days after delivery, and History keeps previews. DELIVER ANYWHERE Dropbox, Google Drive, Google Photos, OneDrive, Box, ShootProof, SmugMug, Photohawk, Flickr, Adobe Lightroom, Frame.io, Slack, Amazon S3, WebDAV, FTP/SFTP and more. Never locked to a proprietary cloud. YOUR OWN SERVER Send shots straight to your FTP or SFTP server, into a new subfolder for each shoot or the exact folder you choose. Once a shot reaches CloudTether, our servers send it on, so your phone doesn't have to stay online for that. MULTIPLE CAMERAS AT ONCE Tether several cameras over USB, Wi-Fi or a mix — each sending to its own destinations. Home shows a live shoot panel, and every camera gets its own Live Activity on the Lock Screen showing where its shots are going and how many are captured, sending and delivered. CONNECT ALMOST ANY CAMERA Canon, Nikon, Sony, Fujifilm, GoPro and many more, over USB or Wi-Fi. Pick your brand, choose your model, and follow the guided setup. BUILT FOR REAL SHOOTS • Full-resolution RAW + JPEG, exactly as the camera recorded them. • Works over Wi-Fi or mobile data; missed uploads catch up automatically when you're back online. • Keep copies of on-phone shots in your Photos library or a folder (including a USB drive or SD reader) as they arrive. • Geotag each photo with your phone's location, matched to the moment you pressed the shutter. KNOW WHERE EVERY PHOTO IS Every shot shows whether it's sending or delivered, and to which service. Anything that needs attention is grouped with a one-tap fix. Open the delivered folder in Dropbox, Drive, OneDrive or Box, or browse your FTP/SFTP folder in the app. ONE SIMPLE PLAN CloudTether is a single subscription — everything included — and starts with a free trial. — CloudTether is an auto-renewing subscription. • Free trial: 7 days, then $7.99/month (prices may vary by region and are shown in the app before you subscribe). • Payment is charged to your Apple ID at confirmation of purchase. • The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. • Manage or cancel anytime in your App Store account settings.

About

SharpStop Depth of Field Calc

Features
Read full description

See what will be sharp before you press the shutter. SharpStop draws the sharp zone on the scene, plans a focus stack shot by shot, and tells you when tonight's Milky Way core is up. Every tool answers in a sentence, not only in numbers: "Sharp from 1.8 m to infinity: you're at hyperfocal", or "4 shots: focus at 0.47, 0.70, 1.4, 2.5 m". DEPTH OF FIELD, DRAWN Camera, subject and horizon in one side view, with the sharp zone shaded from near limit to far limit. Change the focal length, aperture or distance and the band moves with it. The real front-to-back split is spelled out, because the old one-third rule only holds near the hyperfocal distance. One tap focuses at hyperfocal. FOCUS STACKING PLAN Enter the nearest and farthest things that must be sharp. SharpStop works out the fewest shots that cover the range with a small overlap, gives the focus distance for each one and draws the stacked zones on the scene. In the field, tick each frame off on a checklist with big targets, then share the plan as text. MILKY WAY AND STAR TRAILS For a dark-sky site or your own coordinates, you see when the galactic core is up in full darkness, how much of the moon is lit and which way to face, plus the three best nights in the next 30 days. The NPF rule gives the longest exposure before stars trail for your aperture and pixel pitch, with the 500 rule beside it for comparison. Nights you shoot go into a night log. ND FILTERS AND FIELD OF VIEW Your shutter speed with the filter on, in stops, optical density and ND factor at once, with a warning past 30 minutes. Field of view shows what fits in the frame at your subject distance, with a person drawn to scale. YOUR KIT, SAVED Save bodies and lenses and load them with a tap. Six sensor formats from 1 inch to medium format, each with its own circle of confusion. Print a hyperfocal card for any lens as a PDF. A glossary explains every term in plain words. Meters or feet. BUILT FOR THE DARK Amber on black, so a glance at 4 a.m. does not undo your night vision. Everything is calculated on the phone and works offline. The only part that goes online is the feedback form, when you choose to send a message. No account, no ads. WHAT IT IS NOT Depth of field is a standard for acceptable sharpness in a normal-sized print, not a physical edge: at 100% on screen the limits will look soft, and SharpStop says so. The core position is approximate (about half a degree), and weather and light pollution are not included. It does not meter light, model lens breathing or connect to your camera.
