DOUBLE EXPOSURE GHOSTTHE ANALOG GHOST LABORATORYA quiet place to experiment with light.
Blend two photographs. Find the image in between.
Turn on the silhouette mask. Move the trees. Keep one branch away from the eye.
A double exposure is more than a transparent photograph. On film, light from both moments reaches the same light-sensitive surface. Our two modes help you see the difference.
Screen brightens overlapping tones; Multiply darkens them. Lighten keeps the brighter channel value. Normal mixes the second frame over the first using opacity. Try the same pair with each operation before choosing a mood.
For two equally weighted exposures of overlapping subjects, −1 EV each is a useful starting point: half plus half equals one reference exposure. It is not a rule for every scene. Dark backgrounds, subject placement and film latitude change the practical decision.
Red hatching marks two bright sources overlapping. Sage dots mark two dark sources. Brass marks mixed tones. These are source-luminance categories, not an aesthetic score or a guarantee of film detail. The overlay never enters your exported image. The silhouette mask is available in Compose mode; it limits the second layer using the darkness of frame A.
Model note: Expose mode converts display RGB to linear light, adds EV-weighted channels, clips at the reference white, then converts back to display RGB. It does not model a measured film characteristic curve, reciprocity failure, development chemistry, scanner response or a particular stock.
Place vertical trees inside a dark silhouette. Keep the surrounding sky bright and move a trunk away from the eyes.
Overlap two architectural studies. Rotate the second frame, then align its horizon to create an impossible skyline.
Bring a moon into a dark landscape. Compare Screen with linear exposure and watch what happens to the sky.
Demo images are original procedural illustrations, designed to make tonal relationships easy to read. Replace them with your photographs for a photographic result. Loading a study replaces the current sources.
Keep up to six experiments in this tab, compare their settings, and download a contact sheet. Proofs are temporary and disappear when the page reloads.
Start with the supplied silhouette and forest. Select Screen and move frame B until a tree follows the profile. Compare Normal at 50% opacity. Next switch to Expose and set both EV values to −1. Turn on Ghost Map to see where bright sources overlap, then adjust one EV at a time. Export the image when the relationship feels right.
Two bright skies often compete for the same area. Lower one exposure in Expose mode, reposition the subject against a darker region, or choose a high-contrast first image. In Compose mode, reduce opacity or try Multiply. A darker result is not automatically better: preserve the subject that carries the story.
No. This editor reads files you select into browser memory and processes them with Canvas. There is no photo-upload endpoint in the editor. Blogger and Google advertising services may still process normal visit and advertising data.
No. It demonstrates linear light addition with EV weighting. Real film, development, scene contrast and scanning change the result. Use this tool to plan composition, then test on your own camera and stock.
Choose 1800 × 1200 or 900 × 600 pixels in the Finish panel. The live preview uses 900 × 600. Images are center-cropped to a 3:2 frame; moving, scaling and rotating frame B changes its placement. This is not an original-resolution archival editor.
Yes. Use the X/Y number fields or focus the canvas and press arrow keys. Shift plus an arrow moves further. Sliders support keyboard input. Undo and redo store control changes; replacing source files starts a fresh history.
The English and Korean versions have separate page URLs. Switching languages reloads the editor, so export your work first. No photos or proof sheets are saved across reloads.
