Photo editing apps - recommendations?

Yo, I've been down this road too – trying to find photo editing software that actually handles the specific requirements we deal with here. A lot of generic apps just don't cut it. The common issues I ran into? Honestly, images looking washed out after printing, weird color shifts, or the final result not matching the template dimensions. Or sometimes the file would export at the wrong DPI and the barcode or microprint would come out blurry. Really frustrating when you think you've nailed it and then it fails on a scanner test, tbh.

For troubleshooting, first check what's causing the problem. If your edited image looks fine on screen but prints poorly, it's usually a color profile mismatch or resolution drop. If you're losing fine details like holograms or guilloche patterns, your app might be compressing or resampling the image without telling you. Free apps I've found that actually work include GIMP and Photopea – both handle layers, custom brushes, and most importantly let you set the exact DPI and color space (CMYK or RGB depending on the final use). Paint.NET is another lightweight option, though you'll need plugins for layer masks and advanced color adjustments.

The fix, at least for me, was switching to GIMP and learning to use its color management tools. I set the canvas at 300 DPI from the start, work in Adobe RGB (1998) for better color gamut, and always export as PNG or TIFF to avoid JPEG artifacts. Photopea works great for quick edits directly in the browser but I've had issues with some templates losing opacity layers during download. Experiment with a few and see which one gels with your workflow – free doesn't mean limited if you know which features to prioritize.

As for prevention, always keep a master copy of your template as a layered XCF or PSD before flattening. Verify your exported file's properties – DPI, dimensions, color mode – using a tool like IrfanView or even just Windows Properties. And test print on plain paper before committing to the final card stock. That alone saved me from wasting blanks on color calibration errors, tbh. Hope this helps narrow it down!
