Hey Everyone

Hope you're all rosey, i don't know if anyone can help me but i have a rather frustrating issue in Photoshop 7

i have used lighting effects (omni and spotlight), across varies layers on an image and everythings fine and smooth. However when i send this image via an application (email, site uplaod), the render lines suddenly appear really visable and messy. However the exact same image that i sent out when opened in photoshop looks fine. The image is an RGB jpeg saved at 10 compresion, in a 8bit channel.

I'm tearing my hair out with this if anyone can help i'll shower you in sherbert

I've attached the image so i imagine the problem will resurface here

thanks for any help

reported smooth lighting effects inside Photoshop 7 but saw pronounced render "lines" after sending the file. This is almost always posterization/banding made worse by lossy export or downstream recompression: subtle, low-contrast gradients from lighting get reduced to visible steps when tonal precision or file fidelity is lost.

Causes in plain terms: an 8‑bit/channel image only stores 256 tonal steps per channel, and JPEG compression (plus server or mail-client recompression and any resizing) further quantizes and introduces blocking or chroma subsampling. That combo turns a smooth ramp into stripes. Color‑profile or preview scaling differences can also change how those steps appear outside Photoshop.

Suggested workflow and fixes:

  • Keep a high‑precision master. Wherever possible work and render in 16 bits/channel (Image > Mode > 16 Bits/Channel) and do final flattening only when ready to export.
  • Break up banding with controlled noise. Duplicate the finished layer, apply Filter > Noise > Add Noise (1–3%, Gaussian, Monochromatic), set the duplicate to Overlay or Soft Light and lower opacity until the banding disappears. Optionally apply a very small Gaussian Blur to the noise.
  • Export for delivery with minimal recompression. Use a lossless or high‑quality export and convert to sRGB for web display. If a hosting site or mailer resizes/recompresses uploads, supply a larger, well‑compressed source or use an export format the pipeline won’t reencode.
  • If direct 16‑bit filters aren’t available in PS7, render at larger resolution or add subtle dither/noise before converting to 8‑bit.

As noted, avoiding lossy recompression helps — combining that with higher bit depth or subtle dither/noise is the usual practical cure for visible lighting banding.

save the image in png format, anything greater than the 8 bit format will solve the problem
