PS "Loading" problems are caused by resource access or processing problems: hard disk reading speed is slow or bad: Use CrystalDiskInfo to check the hard disk health and replace the problematic hard disk. Insufficient memory: Upgrade memory to meet PS's needs for high-resolution images and complex layer processing. Graphics card drivers are outdated or corrupted: Update the drivers to optimize communication between the PS and the graphics card. File paths are too long or file names have special characters: use short paths and avoid special characters. PS's own problem: Reinstall or repair the PS installer.

A PS stuck on "Loading" when booting can be caused by various reasons: Disable corrupt or conflicting plugins. Delete or rename a corrupted configuration file. Close unnecessary programs or upgrade memory to avoid insufficient memory. Upgrade to a solid-state drive to speed up hard drive reading. Reinstalling PS to repair corrupt system files or installation package issues. View error information during the startup process of error log analysis.

Solving the problem of slow Photoshop startup requires a multi-pronged approach, including: upgrading hardware (memory, solid-state drive, CPU); uninstalling outdated or incompatible plug-ins; cleaning up system garbage and excessive background programs regularly; closing irrelevant programs with caution; avoiding opening a large number of files during startup.

"Loading" stuttering occurs when opening a file on PS. The reasons may include: too large or corrupted file, insufficient memory, slow hard disk speed, graphics card driver problems, PS version or plug-in conflicts. The solutions are: check file size and integrity, increase memory, upgrade hard disk, update graphics card driver, uninstall or disable suspicious plug-ins, and reinstall PS. This problem can be effectively solved by gradually checking and making good use of PS performance settings and developing good file management habits.

The reason for slow PS loading is the combined impact of hardware (CPU, memory, hard disk, graphics card) and software (system, background program). Solutions include: upgrading hardware (especially replacing solid-state drives), optimizing software (cleaning up system garbage, updating drivers, checking PS settings), and processing PS files. Regular computer maintenance can also help improve PS running speed.

PS card is "Loading"? Solutions include: checking the computer configuration (memory, hard disk, processor), cleaning hard disk fragmentation, updating the graphics card driver, adjusting PS settings, reinstalling PS, and developing good programming habits.

There are three ways to export PDFs in batches on PS: use PS action functions: record and open files and export PDF actions, and execute actions in a loop. With the help of third-party software: use file management software or automation tools to specify the input and output folders and set the file name format. Use scripts: Write scripts to customize batch export logic, but programming knowledge is required.

The key to feather control is to understand its gradual nature. PS itself does not provide the option to directly control the gradient curve, but you can flexibly adjust the radius and gradient softness by multiple feathering, matching masks, and fine selections to achieve a natural transition effect.
